H1: Database Creation and Maintenance Tools
-This section tells you how to create a slapd database from
-scratch, and how to do trouble shooting if you run into
-problems. There are two ways to create a database. First,
-you can create the database on-line using LDAP. With this
-method, you simply start up slapd and add entries using the
-LDAP client of your choice. This method is fine for relatively
-small databases (a few hundred or thousand entries,
-depending on your requirements).
-
-The second method of database creation is to do it off-line,
-using the index generation tools. This method is best if you
-have many thousands of entries to create, which would take
-an unacceptably long time using the LDAP method, or if you
-want to ensure the database is not accessed while it is
-being created.

+have many thousands of entries to create, which would take an
+unacceptably long time using the LDAP method, or if you want to
+ensure the database is not accessed while it is being created. Note
+that not all database types support these utilitites.
H2: Creating a database over LDAP
-With this method, you use the LDAP client of your choice
-(e.g., the ldapadd(1) tool) to add entries, just like you would
-once the database is created. You should be sure to set the
-following configuration options before starting slapd:
+With this method, you use the LDAP client of your choice (e.g.,
+the {{ldapadd}}(1)) to add entries, just like you would once the
+database is created. You should be sure to set the following
+options in the configuration file before starting {{slapd}}(8).
-E: suffix <dn>
+> suffix <dn>
-As described in the preceding section, this option says what
-entries are to be held by this database. You should set this
-to the DN of the root of the subtree you are trying to create.
-For example
+As described in the {{SECT:General Database Directives}} section,
+this option defines which entries are to be held by this database.
+You should set this to the DN of the root of the subtree you are
+trying to create. For example:
-E: suffix "dc=OpenLDAP, dc=org"
+> suffix "dc=example,dc=com"
-You should be sure to specify a directory where the index
-files should be created:
+You should be sure to specify a directory where the index files
+should be created:
-E: directory <directory>
+> directory <directory>
For example:
-E: directory /usr/local/openldap/slapd
+> directory /usr/local/var/openldap-data
-You need to make it so you can connect to slapd as
-somebody with permission to add entries. This is done
-through the following two options in the database definition:
+You need to create this directory with appropriate permissions such
+that slapd can write to it.
-E: rootdn <dn>
-E: rootpw <passwd>
+You need to configure slapd so that you can connect to it as a
+directory user with permission to add entries. You can configure
+the directory to support a special {{super-user}} or {{root}} user
+just for this purpose. This is done through the following two
+options in the database definition:
-These options specify a DN and password that can be used
-to authenticate as the "superuser" entry of the database (i.e.,
-the entry allowed to do anything). The DN and password
-specified here will always work, regardless of whether the
-entry named actually exists or has the password given. This
-solves the chicken-and-egg problem of how to authenticate
-and add entries before any entries yet exist.
+> rootdn <dn>
+> rootpw <passwd>
-Finally, you should make sure that the database definition
-contains the index definitions you want:
-
-E: index {<attrlist> | default} [pres,eq,approx,sub,none]
-
-For example, to index the cn, sn, uid and objectclass
-attributes the following index configuration lines could be
-used.
+For example:
-E: index cn,sn,uid
-E: index objectclass pres,eq
-E: index default none
+> rootdn "cn=Manager,dc=example,dc=com"
+> rootpw secret
-See Section 4 on the configuration file for more details on
-this option. Once you have configured things to your liking,
-start up slapd, connect with your LDAP client, and start
-adding entries. For example, to add a the organizational entry
-followed by a Postmaster entry using the {{I:ldapadd}} tool, you
-could create a file called {{EX:/tmp/newentry}} with the contents:
+These options specify a DN and password that can be used to
+authenticate as the {{super-user}} entry of the database (i.e.,
+the entry allowed to do anything). The DN and password specified
+here will always work, regardless of whether the entry named actually
+exists or has the password given. This solves the chicken-and-egg
+problem of how to authenticate and add entries before any entries
+yet exist.
+Finally, you should make sure that the database definition contains
+the index definitions you want:
-E: dc=OpenLDAP, dc=org
-E: objectClass=dcObject
-E: objectClass=organization
-E: dc=OpenLDAP
-E: o=OpenLDAP
-E: o=OpenLDAP Project
-E: o=OpenLDAP Foundation
-E: description=The OpenLDAP Foundation
-E: description=The OpenLDAP Project
-E:
-E: cn=Postmaster, dc=OpenLDAP, dc=org
-E: objectClass=organizationalRole
-E: cn=Postmaster
-E: description=OpenLDAP Postmaster <Postmaster@OpenLDAP.org>
+> index {<attrlist> | default} [pres,eq,approx,sub,none]
-and then use a command like this to actually create the
-entry:
+For example, to index the {{EX:cn}}, {{EX:sn}}, {{EX:uid}} and
+{{EX:objectclass}} attributes, the following {{EX:index}} directives
+could be used:
-E: ldapadd -f /tmp/newentry -D "cn=Manager, dc=OpenLDAP, dc=org" -w secret
+> index cn,sn,uid
+> index objectClass pres,eq
-The above command assumes that you have set {{EX: rootdn}} to
-"cn=Manager, dc=OpenLDAP, dc=org" and {{EX: rootpw}}
-to "secret".
+Note that not all index types are available with all attribute types.
+See {{SECT:The slapd Configuration File}} section for more details on
+this option. Once you have configured things to your liking, start up
+slapd, connect with your LDAP client, and start adding entries. For
+example, to add an organization entry and an organizational role entry
+using the {{I:ldapadd}} tool, you could create an {{TERM:LDIF}} file
+called {{EX:entries.ldif}} with the contents:
+> # Organization for Example Corporation
+> dn: dc=example,dc=com
+> objectClass: dcObject
+> objectClass: organization
+> dc: example
+> o: Example Corporation
+> description: The Example Corporation
+>
+> # Organizational Role for Directory Manager
+> dn: cn=Manager,dc=example,dc=com
+> objectClass: organizationalRole
+> cn: Manager
+> description: Directory Manager
-H2: Creating a database off-line
+and then use a command like this to actually create the entry:
-The second method of database creation is to do it off-line,
-using the index generation tools described below. This
-method is best if you have many thousands of entries to
-create, which would take an unacceptably long time using
-the LDAP method described above. These tools read the
-slapd configuration file and an input file containing a text
-representation of the entries to add. They produce the LDBM
-index files directly. There are several important configuration
-options you will want to be sure and set in the config file
-database definition first:
+> ldapadd -f entries.ldif -x -D "cn=Manager,dc=example,dc=com" -w secret
-E: suffix <dn>
+The above command assumes settings provided in the above examples.
-As described in the preceding section, this option says what
-entries are to be held by this database. You should set this
-to the DN of the root of the subtree you are trying to create.
-For example
-E: suffix "dc=OpenLDAP, dc=org"
+H2: Creating a database off-line
-You should be sure to specify a directory where the index
-files should be created:

+the slapd database tools described below. This method is best if
+you have many thousands of entries to create, which would take an
+unacceptably long time to add using the LDAP method described above.
+These tools read the slapd configuration file and an input file
+containing a text representation of the entries to add. For database
+types which support the tools, they produce the database files
+directly (otherwise you must use the on-line method above). There
+are several important configuration options you will want to be
+sure and set in the config file database definition first:
-E: directory <directory>
+> suffix <dn>
-For example:
+As described in the {{SECT:General Database Directives}} section,
+this option defines which entries are to be held by this database.
+You should set this to the DN of the root of the subtree you are
+trying to create. For example:
-E: directory /usr/local/var/openldap
+> suffix "dc=example,dc=com"
-Next, you probably want to increase the size of the in-core
-cache used by each open index file. For best performance
-during index creation, the entire index should fit in memory. If
-your data is too big for this, or your memory too small, you
-can still make it pretty big and let the paging system do the
-work. This size is set with the following option:
+You should be sure to specify a directory where the index files
+should be created:
-E: dbcachesize <integer>
+> directory <directory>
For example:
-E: dbcachesize 50000000
+> directory /usr/local/var/openldap-data
-This would create a cache 50 MB big, which is pretty big (at
-U-M, our database has about 125K entries, and our biggest
-index file is about 45 MB). Experiment with this number a bit,
-and the degree of parallelism (explained below), to see what
-works best for your system. Remember to turn this number
-back down once your index files are created and before you
-run slapd.
+Finally, you need to specify which indices you want to build. This
+is done by one or more index options.
-Finally, you need to specify which indexes you want to build.
-This is done by one or more index options.
-
-E: index {<attrlist> | default} [pres,eq,approx,sub,none]
+> index {<attrlist> | default} [pres,eq,approx,sub,none]
For example:
-E: index cn,sn,uid pres,eq,approx
-E: index default none
+> index cn,sn,uid pres,eq,sub
+> index objectClass eq
-This would create presence, equality and approximate
-indexes for the cn, sn, and uid attributes, and no indexes for
-any other attributes. See the configuration file section for
-more information on this option.
+This would create presence, equality and substring indices for
+the {{EX:cn}}, {{EX:sn}}, and {{EX:uid}} attributes and an equality
+index for the {{EX:objectClass}} attribute. See
+{{SECT:The slapd Configuration File}} section
+for more information on this option.
-H3: The {{EX: ldif2ldbm}} program
+H3: The {{EX:slapadd}} program
-Once you've configured things to your liking, you create the
-indexes by running the ldif2ldbm program:
+Once you've configured things to your liking, you create the primary
+database and associated indices by running the {{slapadd}}(8)
+program:
-E: ldif2ldbm -i <inputfile> -f <slapdconfigfile>
-E: [-d <debuglevel>] [-j <integer>]
-E: [-n <databasenumber>] [-e <etcdir>]
+> slapadd -l <inputfile> -f <slapdconfigfile>
+> [-d <debuglevel>] [-n <integer>|-b <suffix>]
The arguments have the following meanings:
-E: -i <inputfile>
-
-Specifies the LDIF input file containing the entries to add in
-text form (described below in Section 8.3).
-
-E: -f <slapdconfigfile>
-
-Specifies the slapd configuration file that tells where to
-create the indexes, what indexes to create, etc.
-
-E: -d <debuglevel>
-
-Turn on debugging, as specified by {{EX: <debuglevel>}}. The
-debug levels are the same as for slapd (see Section 6.1).
-
-E: -j <integer>
-
-An optional argument that specifies that at most {{EX: <integer>}}
-processes should be started in parallel when building the
-indexes. The default is 1. If set to a value greater than one,
-{{I: ldif2ldbm}} will create at most that many subprocesses at a
-time when building the indexes. A separate subprocess is
-created to build each attribute index. Running these
-processes in parallel can speed things up greatly, but
-beware of creating too many processes, all competing for
-memory and disk resources.
-
-E: -n <databasenumber>
-
-An optional argument that specifies the configuration file
-database for which to build indices. The first database listed
-is "1", the second "2", etc. By default, the first ldbm database
-in the configuration file is used.
-
-E: -e <etcdir>
-
-An optional argument that specifies the directory where
-{{EX: ldif2ldbm}} can find the other database conversion tools it
-needs to execute ({{EX: ldif2index}} and friends). The default is the
-installation {{EX: ETCDIR}}.
-
-The next sections describe the programs invoked by
-{{I: ldif2ldbm}} when it is building indexes. Normally, these
-programs are invoked for you, but occasionally you may
-want to invoke them yourself.
-
-
-
-H3: The {{EX: ldif2index}} program
-
-Sometimes it may be necessary to create a new attribute
-index file without disturbing the rest of the database. This is
-possible using the {{EX: ldif2index}} program. {{EX: ldif2index}} is invoked
-like this
-
-E: ldif2index -i <inputfile> -f <slapdconfigfile>
-E: [-d <debuglevel>] [-n <databasenumber>] <attr>
+> -l <inputfile>
-Where the -i, -f, -d, and -n options are the same as for the
-{{I: ldif2ldbm}} program. {{EX: <attr>}} is the attribute to build an index for.
-Which indexes are built (e.g., equality, substring, etc.) is
-controlled by the corresponding index line in the slapd
-configuration file.
+Specifies the LDIF input file containing the entries to add in text
+form (described below in the {{SECT:The LDIF text entry format}}
+section).
-You can use the ldbmcat program to create a suitable LDIF
-input file from an existing LDBM database.
+> -f <slapdconfigfile>
+Specifies the slapd configuration file that tells where to create
+the indices, what indices to create, etc.
+> -d <debuglevel>
-H3: The {{EX: ldif2id2entry}} program
+Turn on debugging, as specified by {{EX:<debuglevel>}}. The debug
+levels are the same as for slapd. See the {{SECT:Command-Line
+Options}} section in {{SECT:Running slapd}}.
-The {{EX: ldif2id2entry}} program is normally invoked from {{EX: ldif2ldbm}}.
-It is used to convert an LDIF text file into an {{EX: id2entry}} index.
-It is unlikely that you would need to invoke it yourself, but if
-you do it works like this
+> -n <databasenumber>
-E: ldif2id2entry -i <inputfile> -f <slapdconfigfile>
-E: [-d <debuglevel>] [-n <databasenumber>]
+An optional argument that specifies which database to modify. The
+first database listed in the configuration file is {{EX:1}}, the
+second {{EX:2}}, etc. By default, the first database in the
+configuration file is used. Should not be used in conjunction with
+{{EX:-b}}.
-The arguments are the same as for the {{EX: ldif2ldbm}} program.
+> -b <suffix>
+An optional argument that specifies which database to modify. The
+provided suffix is matched against a database {{EX:suffix}} directive
+to determine the database number. Should not be used in conjunction
+with {{EX:-n}}.
-H3: The {{EX: ldif2id2children}} program
+H3: The {{EX:slapindex}} program
-The {{EX: ldif2id2children}} program is normally invoked from
-{{EX: ldif2ldbm}}. It is used to convert an LDIF text file into
-{{EX: id2children}} and {{EX: dn2id}} indexes. Occasionally, it may be
-necessary to run this program yourself, for example if one of
-these indexes has become corrupted. {{EX: ldif2id2children}} is
-invoked like this
+Sometimes it may be necessary to regenerate indices (such as after
+modifying {{slapd.conf}}(5)). This is possible using the {{slapindex}}(8)
+program. {{slapindex}} is invoked like this
-E: ldif2id2children -i <inputfile> -f <slapdconfigfile>
-E: [-d <debuglevel>] [-n <databasenumber>]
+> slapindex -f <slapdconfigfile>
+> [-d <debuglevel>] [-n <databasenumber>|-b <suffix>]
-The arguments are the same as for the {{EX: ldif2ldbm}} program.
-You can use the ldbmcat program to create a suitable LDIF
-input file from an existing LDBM database.
+Where the {{EX:-f}}, {{EX:-d}}, {{EX:-n}} and {{EX:-b}} options
+are the same as for the {{slapadd}}(1) program. {{slapindex}}
+rebuilds all indices based upon the current database contents.
+H3: The {{EX:slapcat}} program
-H3: The {{EX: ldbmcat}} program
+The {{EX:slapcat}} program is used to dump the database to an
+{{TERM:LDIF}} file. This can be useful when you want to make a
+human-readable backup of your database or when you want to edit
+your database off-line. The program is invoked like this:
-The {{EX: ldbmcat}} program is used to convert an {{EX: id2entry}} index
-back into its LDIF text format. This can be useful when you
-want to make a human-readable backup of your database,
-or as an intermediate step in creating a new index using the
-{{EX: ldif2index}} program. The program is invoked like this:
+> slapcat -l <filename> -f <slapdconfigfile>
+> [-d <debuglevel>] [-n <databasenumber>|-b <suffix>]
-E: ldbmcat [-n] <filename>
+where {{EX:-n}} or {{EX:-b}} is used to select the database in the
+{{slapd.conf}}(5) specified using {{EX:-f}}. The corresponding
+LDIF output is written to standard output or to the file specified
+using the {{EX:-l}} option.
-where {{EX: <filename>}} is the name of the {{EX: id2entry}} index file. The
-corresponding LDIF output is written to standard output.
-The -n option can be used to prevent the printing of entry
-IDs in the LDIF format. If you are creating an LDIF format for
-use as input to {{EX: ldif2index}} or anything by {{EX: ldif2ldbm}}, you
-should not use the -n option (because the entry IDs must
-match those already in the id2entry file). If you are just
-making a backup of your data, you can use the -n option to
-save space.
+!if 0
+H3: The {{EX:ldif}} program
+The {{ldif}}(1) program is used to convert arbitrary data values
+to {{TERM:LDIF}} format. This can be useful when writing a program
+or script to create the LDIF file you will feed into the {{slapadd}}(8)
+or {{ldapadd}}(1) program, or when writing a SHELL backend.
+{{ldif}}(1) takes an attribute description as an argument and reads
+the attribute value(s) from standard input. It produces the LDIF
+formatted attribute line(s) on standard output. The usage is:
+> ldif [-b] <attrdesc>
-H3: The {{EX: ldif}} program
+where {{EX:<attrdesc>}} is an attribute description. Without the
+{{EX-b}} option, the {{ldif}} program will consider each line of
+standard input to be a separate value of the attribute.
-The ldif program is used to convert arbitrary data values to
-LDIF format. This can be useful when writing a program or
-script to create the LDIF file you will feed into the ldif2ldbm
-program, or when writing a SHELL backend. ldif takes an
-attribute name as an argument, and reads the attribute
-value(s) from standard input. It produces the LDIF formatted
-attribute line(s) on standard output. The usage is:
+> ldif description << EOF
+> leading space
+> # leading hash mark
+> EOF
-E: ldif [-b] <attrname>
+The {{EX:-b}} option can be used to force the {{ldif}} program to
+interpret its input as a single raw binary value. This option is
+useful when converting binary data such as a {{EX:jpegPhoto}} or
+{{EX:audio}} attribute. For example:
-where {{EX: <attrname>}} is the name of the attribute. Without the
--b option, ldif considers each line of standard input to be a
-separate value of the attribute.
-
-The -b option can be used to force ldif to interpret its input
-as a single raw binary value. This option is useful when
-converting binary data such as a {{EX: jpegPhoto}} or {{EX: audio}}
-attribute.
+> ldif -b jpegPhoto < photo.jpeg
+!endif
H2: The LDIF text entry format
-The LDAP Data Interchange Format (LDIF) is used to
-represent LDAP entries in a simple text format. The basic
-form of an entry is:
-
-E: [<id>]
-E: dn: <distinguished name>
-E: <attrtype>: <attrvalue>
-E: <attrtype>: <attrvalue>
-E:
-E: ...
-
-where {{EX: <id>}} is the optional entry ID (a positive decimal
-number). Normally, you would not supply the {{EX: <id>}}, allowing
-the database creation tools to do that for you. The ldbmcat
-program, however, produces an LDIF format that includes
-{{EX: <id>}} so that new indexes created will be consistent.
-
-A line may be continued by starting the next line with a
-single space or tab character. e.g.,
-
-E: dn: cn=Barbara J Jensen, dc=OpenLDAP, dc=org
-
-Multiple attribute values are specified on separate lines. e.g.,
-
-E: cn: Barbara J Jensen
-E: cn: Babs Jensen
-
-If an {{EX: <attrvalue>}} contains a non-printing character, or
-begins with a space or a colon `:', the {{EX: <attrtype>}} is followed
-by a double colon and the value is encoded in base 64
-notation. e.g., the value " begins with a space" would be
-encoded like this:
-
-E: cn:: IGJlZ2lucyB3aXRoIGEgc3BhY2U=
-
-Multiple entries within the same LDIF file are separated by
-blank lines. Here's an example of an LDIF file containing
-three entries.
-
-E: dn: cn=Barbara J Jensen, dc=OpenLDAP, dc=org
-E: cn: Barbara J Jensen
-E: cn: Babs Jensen
-E: objectclass: person
-E: sn: Jensen
-E:
-E:
-E: dn: cn=Bjorn J Jensen, dc=OpenLDAP, dc=org
-E: cn: Bjorn J Jensen
-E: cn: Bjorn Jensen
-E: objectclass: person
-E: sn: Jensen
-E:
-E: dn: cn=Jennifer J Jensen, dc=OpenLDAP, dc=org
-E: cn: Jennifer J Jensen
-E: cn: Jennifer Jensen
-E: objectclass: person
-E: sn: Jensen
-E: jpegPhoto:: /9j/4AAQSkZJRgABAAAAAQABAAD/2wBDABALD
-E: A4MChAODQ4SERATGCgaGBYWGDEjJR0oOjM9PDkzODdASFxOQ
-E: ERXRTc4UG1RV19iZ2hnPk1xeXBkeFxlZ2P/2wBDARESEhgVG
-E:
-E: ...
-
-Notice that the {{EX: jpegPhoto}} in Jennifer Jensen's entry is
-encoded using base 64. The {{EX: ldif}} program (described in
-Section 8.2.6) can be used to produce the LDIF format.
-
-Note: Trailing spaces are not trimmed from values in an
-LDIF file. Nor are multiple internal spaces compressed. If
-you don't want them in your data, don't put them there.
-
-
-H2: Converting from QUIPU EDB format to LDIF format
-
-If you have directory data that is or was held in a QUIPU
-DSA (available as part of the ISODE package), you will want
-to convert the EDB files used by QUIPU into an LDIF file.
-The edb2ldif program is provided to do most of the
-conversion for you. Once you have an LDIF file, you should
-follow the steps outlined in section 6.2 above to build an
-LDBM database for slapd.
-
-
-
-H3: The {{EX: edb2ldif}} program
-
-The edb2ldif program is invoked like this:
-
-E: edb2ldif [-d] [-v] [-r] [-o] [-b <basedn>]
-E: [-a <addvalsfile>] [-f <fileattrdir>]
-E: [-i <ignoreattr...>] [<edbfile...>]
-
-The LDIF data is written to standard output. The arguments
-have the following meanings:
+The {{TERM[expand]LDIF}} (LDIF) is used to represent LDAP entries
+in a simple text format. This section provides a brief description
+of the LDIF entry format which complements {{ldif}}(5) and the
+technical specification {{REF:RFC2849}}.
-E: -d
+The basic form of an entry is:
-This option enables some debugging output on standard
-error.
+> # comment
+> dn: <distinguished name>
+> <attrdesc>: <attrvalue>
+> <attrdesc>: <attrvalue>
+>
+> ...
-E: -v
+Lines starting with a '{{EX:#}}' character are comments. An
+attribute description may be a simple attribute type like {{EX:cn}}
+or {{EX:objectClass}} or {{EX:1.2.3}} (an {{TERM:OID}} associated
+with an attribute type) or may include options such as {{EX:cn;lang_en_US}}
+or {{EX:userCertificate;binary}}.
-Enable verbose mode that writes status information to
-standard error, such as which EDB file is being processed,
-how many entries have been converted so far, etc.
+A line may be continued by starting the next line with a {{single}}
+space or tab character. For example:
-E: -r
+> dn: cn=Barbara J Jensen,dc=example,dc=
+> com
+> cn: Barbara J
+> Jensen
-Recurse through child directories, processing all EDB files
-found.
+is equivalent to:
-E: -o
+> dn: cn=Barbara J Jensen,dc=example,dc=com
+> cn: Barbara J Jensen
-Cause local .add file definitions to override the global addfile
-(see -a below)
-
-E: -b <basedn>
-
-Specify the Distinguished Name that all EDB file entries
-appear below.
-
-E: -a <addvalsfile>
-
-The LDIF information contained in this file will be appended
-to each entry.
-
-E: -f <fileattrdir>
-
-Specify a single directory where all file-based attributes
-(typically sounds and images) can be found. If this option is
-not given, file attributes are assumed to be located in the
-same directory as the EDB file that refers to them.
-
-E: -i <ignoreattr>
-
-Specify an attribute that should not be converted. You can
-include as many -i flags as necessary.
-
-E: <edbfile>
-
-Specify a particular EDB file (or files) to read data from. By
-default, the EDB.root (if it exists) and EDB files in the current
-directory are used.
-
-When {{EX: edb2ldif}} is invoked, it will also look for files named
-.add in the directories where EDB files are found and append
-the contents of the .add file to each entry. Typically, this
-feature is used to include inherited attribute values (e.g.,
-{{EX: objectClass}}) that do not appear in the EDB files.
-

-
-H3: Step-by-step EDB to LDIF conversion
-
-The basic steps to follow when converting your EDB format
-data to an LDIF file are:
-
-^ Locate the directory at the top of the EDB file hierarchy
-that your QUIPU DSA masters. The EDB file located there
-should contain the entries for the first level of your
-organization or organizational unit. If you are using an
-indexed database with QUIPU, you may need to create EDB
-files from your index files (using the synctree or qb2edb
-tools).
-
-
-+ If you do not have a file named EDB.root in the same
-directory that contains your organizational or organizational
-unit entry, create it now by hand. Its contents should look
-something like this:
-
-.{{EX: MASTER}}
-.{{EX: 000001}}
-.{{EX: }}
-.{{EX: o=OpenLDAP}}
-.{{EX: objectClass= top & organization & domainRelatedObject &\}}
-.{{EX: quipuObject & quipuNonLeafObject}}
-.{{EX: l= Redwood City, California}}
-.{{EX: st= California}}
-.{{EX: o=OpenLDAP Project & OpenLDAP Foundation & OpenLDAP}}
-.{{EX: description=The OpenLDAP Project}}
-.{{EX: associatedDomain= openldap.org}}
-.{{EX: masterDSA= c=US@cn=Woolly Monkey}}
-.{{EX: }}
-
-+ (Optional) Create a global add file and/or local .add files to
-take care of adding any attribute values that do not appear in
-the EDB files. For example, if all entries in a particular EDB
-are person entries and you want to add the appropriate
-objectClass attribute value for them, create a file called .add
-in the same directory as the person EDB that contains the
-single line:
-
-.{{EX: objectClass: person }}
-
-
-+ Run the edb2ldif program to do the actual conversion.
-Make sure you are in the directory that contains the root of
-the EDB hierarchy (the one where the EDB.root file resides).
-Include a -b flag with a base DN one level above your
-organizational entry, and include -i flags to ignore any
-attributes that are not useful to slapd. E.g., the command:
-
-.{{EX: edb2ldif -v -r -b "c=US" -i iattr -i acl -i xacl -i sacl}}
-.{{EX: -i lacl -i masterDSA -i slaveDSA > ldif}}
-
-will convert the entire EDB hierarchy to LDIF format and
-write the result to a file named ldif. Some attributes that are
-not useful when running slapd are ignored. The EDB
-hierarchy is assumed to reside logically below the base DN
-"c=US".
-
-+ Follow the steps outlined in section 8.2 above to produce
-an LDBM database from your new LDIF file.
-
-
-
-H2: The ldbmtest program
-
-Occasionally you may find it useful to look at the LDBM
-database and index files directly (i.e., without going through
-slapd). The {{EX: ldbmtest}} program is provided for this purpose. It
-gives you raw access to the database itself. {{EX: ldbmtest}} should
-be run line this:
-
-E: ldbmtest [-d <debuglevel>] [-f <slapdconfigfile>]
-
-The default configuration file in the {{EX: ETCDIR}} is used if you
-don't supply one. By default, ldbmtest operates on the last
-database listed in the config file. You can specify an
-alternate database, or see the current database with the
-following commands.
-
-E: b specify an alternate backend database
-E: B print out the current backend database
-
-The {{EX: b}} command will prompt you for the suffix associated with
-the database you want. The database you select can be
-viewed and modified using a set of two-letter commands.
-The first letter selects the command function to perform.
-Possible commands and their meanings are as follows.
-
-E: l lookup (do not follow indirection)
-E: L lookup (follow indirection)
-E: t traverse and print keys and data
-E: T traverse and print keys only
-E: x delete an index item
-E: e edit an index item
-E: a add an index item
-E: c create an index file
-E: i insert an entry into an index item
-
-The second letter indicates which index the command
-applies to. The possible index selections are as follows.
-
-E: c id2children index
-E: d dn2id index
-E: e id2entry index
-E: f arbitrary file name
-E: i attribute index
-
-Each command may require additional arguments which
-ldbmtest will prompt you for.
-
-To exit {{EX: ldbmtest}}, type {{EX: control-D}} or {{EX: control-C}}.
-
-Note that this is a very raw interface originally developed
-when testing the database format. It is provided and
-minimally documented here for interested parties, but it is not
-meant to be used by the inexperienced. See the next section
-for a brief description of the LDBM database format.

-
-
-H2: The LDBM database format
-
-In normal operation, it is not necessary for you to know much
-about the LDBM database format. If you are going to use the
-ldbmtest program to look at or alter the database, or if you
-want a deeper understanding of how indexes are maintained,
-some knowledge of how it works could be useful. This
-section gives an overview of the database format and how
-slapd makes use of it.
-
-
-
-H3: Overview
-
-The LDBM database works by assigning a compact
-four-byte unique identifier to each entry in the database. It
-uses this identifier to refer to entries in indexes. The
-database consists of one main index file, called id2entry,
-which maps from an entry's unique identifier (EID) to a text
-representation of the entry itself. Other index files are
-maintained, for each indexed attribute for example, that map
-values people are likely to search on to lists of EIDs.
-
-Using this simple scheme, many LDAP queries can be
-answered efficiently. For example, to answer a search for
-entries with a surname of "Jensen", slapd would first consult
-the surname attribute index, look up the value "Jensen" and
-retrieve the corresponding list of EIDs. Next, slapd would
-look up each EID in the id2entry index, retrieve the
-corresponding entry, convert it from text to LDAP format, and
-return it to the client.
-
-The following sections give a very brief overview of each
-type of index and what it contains. For more detailed
-information see the paper "An X.500 and LDAP Database:
-Design and Implementation," available in postscript format
-from
-{{URL:ftp://terminator.rs.itd.umich.edu/ldap/papers/xldbm.ps}}
-
-
-H3: Attribute index format
-
-The LDBM backend will maintain one index file for each
-attribute it is asked to index. Several sets of keys must
-coexist in this file (e.g., keys for equality and approximate
-equality), so the keys are prefixed with a character to ensure
-uniqueness. The prefixes are given in the table below
-
-E: = equality keys
-E: ~ approximate equality keys
-E: * substring equality keys
-E: \ continuation keys
-
-Key values are also normalized (e.g., converted to upper
-case for case ignore attributes). So, for example, to look up
-the surname equality value in the example above using the
-ldbmtest program, you would look up the value "{{EX: =JENSEN}}".
-
-Substring indexes are maintained by generating all possible
-N-character substrings for a value (N is 3 by default). These
-substrings are then stored in the attribute index, prefixed by
-"*". Additional anchors of "^" and "$" are added at the
-beginning and end of words. So, for example the surname of
-Jensen would cause the following keys to be entered in the
-index: {{EX: ^JE, JEN, ENS, NSE, SEN, EN$}}.
-
-Approximate values are handled in a similar way, with
-phonetic codes being generated for each word in a value
-and then stored in the index, prefixed by "~".
-
-Large blocks in the index are split into smaller ones. The
-smaller blocks are accessed through a level of indirection
-provided by the original block. They are stored in the index
-using the continuation key prefix of "\".
-
-
-
-H3: Other indexes
-
-In addition to the {{EX: id2entry}} and attribute indexes, LDBM
-maintains a number of other indexes, including the {{EX: dn2id}}
-index and the {{EX: id2children}} index. These indexes provide the
-mapping between a DN and the corresponding EID, and the
-mapping between an EID and the EIDs of the corresponding
-entry's children, respectively.
-
-The {{EX: dn2id}} index stores normalized DNs as keys. The data
-stored is the corresponding EID.
-
-The {{EX: id2children}} index stores EIDs as keys. The data stored
-is a list of EIDs, just as for the attribute indexes.
+Multiple attribute values are specified on separate lines. e.g.,
+> cn: Barbara J Jensen
+> cn: Babs Jensen
+
+If an {{EX:<attrvalue>}} contains non-printing characters or begins
+with a space, a colon ('{{EX::}}'), or a less than ('{{EX:<}}'),
+the {{EX:<attrdesc>}} is followed by a double colon and the base64
+encoding of the value. For example, the value "{{EX: begins with
+a space}}" would be encoded like this:
+
+> cn:: IGJlZ2lucyB3aXRoIGEgc3BhY2U=
+
+You can also specify a {{TERM:URL}} containing the attribute value.
+For example, the following specifies the {{EX:jpegPhoto}} value
+should be obtained from the file {{F:/path/to/file.jpeg}}.
+
+> cn:< file:///path/to/file.jpeg
+
+Multiple entries within the same LDIF file are separated by blank
+lines. Here's an example of an LDIF file containing three entries.
+
+> # Barbara's Entry
+> dn: cn=Barbara J Jensen,dc=example,dc=com
+> cn: Barbara J Jensen
+> cn: Babs Jensen
+> objectClass: person
+> sn: Jensen
+>
+> # Bjorn's Entry
+> dn: cn=Bjorn J Jensen,dc=example,dc=com
+> cn: Bjorn J Jensen
+> cn: Bjorn Jensen
+> objectClass: person
+> sn: Jensen
+> # Base64 encoded JPEG photo
+> jpegPhoto:: /9j/4AAQSkZJRgABAAAAAQABAAD/2wBDABALD
+> A4MChAODQ4SERATGCgaGBYWGDEjJR0oOjM9PDkzODdASFxOQ
+> ERXRTc4UG1RV19iZ2hnPk1xeXBkeFxlZ2P/2wBDARESEhgVG
+>
+> # Jennifer's Entry
+> dn: cn=Jennifer J Jensen,dc=example,dc=com
+> cn: Jennifer J Jensen
+> cn: Jennifer Jensen
+> objectClass: person
+> sn: Jensen
+> # JPEG photo from file
+> jpegPhoto:< file:///path/to/file.jpeg
+
+Notice that the {{EX:jpegPhoto}} in Bjorn's entry is base 64 encoded
+and the {{EX:jpegPhoto}} in Jennifer's entry is obtained from the
+location indicated by the URL.
+
+Note: Trailing spaces are not trimmed from values in an LDIF file.
+Nor are multiple internal spaces compressed. If you don't want them
+in your data, don't put them there.
