-.SH OPTIONS
+.SH SYNTAX
The configuration options are case-insensitive;
their value, on a case by case basis, may be case-sensitive.
.LP
-Blank lines and lines beginning with a hash mark (`#')
-are ignored up to their end.
+Blank lines are ignored.
+.br
+Lines beginning with a hash mark (`#') are comments, and ignored.
.LP
Valid lines are made of an option's name (a sequence of non-blanks,
conventionally written in uppercase, although not required),
may be incorrect, as the quotes would become part of the value.
For example,
- URI "ldap:// ldaps://"
+.nf
+ # Wrong - erroneous quotes:
+ URI "ldap:// ldaps://"
-is incorrect, while
+ # Right - space-separated list of URIs, without quotes:
+ URI ldap:// ldaps://
- URI ldap:// ldaps://
+ # Right - DN syntax needs quoting for Example, Inc:
+ BASE ou=IT staff,o="Example, Inc",c=US
+ # or:
+ BASE ou=IT staff,o=Example2C Inc,c=US
-is correct (note the absence of the double quotes).
+ # Wrong - comment on same line as option:
+ DEREF never # Never follow aliases
+.fi
.LP
A line cannot be longer than LINE_MAX, which should be more than 2000 bytes
on all platforms.
There is no mechanism to split a long line on multiple lines, either for
beautification or to overcome the above limit.

+.SH OPTIONS
The different configuration options are:
.TP
.B URI <ldap[si]://[name[:port]] ...>
.B BINDDN <dn>
Specifies the default bind DN to use when performing ldap operations.
The bind DN must be specified as a Distinguished Name in LDAP format.
-.B This is a user\-only option.
+.B This is a user-only option.
.TP
.B DEREF <when>
Specifies how alias dereferencing is done when performing a search. The
.\"Determines whether the library should implicitly restart connections (FIXME).
.TP
.B SIZELIMIT <integer>
-Specifies a size limit to use when performing searches. The
-number should be a non-negative integer. \fISIZELIMIT\fP of zero (0)
-specifies unlimited search size.
+Specifies a size limit (number of entries) to use when performing searches.
+The number should be a non-negative integer. \fISIZELIMIT\fP of zero (0)
+specifies a request for unlimited search size. Please note that the server
+may still apply any server-side limit on the amount of entries that can be
+returned by a search operation.
.TP
.B TIMELIMIT <integer>
-Specifies a time limit to use when performing searches. The
-number should be a non-negative integer. \fITIMELIMIT\fP of zero (0)
-specifies unlimited search time to be used.
+Specifies a time limit (in seconds) to use when performing searches.
+The number should be a non-negative integer. \fITIMELIMIT\fP of zero (0)
+specifies unlimited search time to be used. Please note that the server
+may still apply any server-side limit on the duration of a search operation.
.B VERSION {2|3}
Specifies what version of the LDAP protocol should be used.
.TP
.TP
.B SASL_MECH <mechanism>
Specifies the SASL mechanism to use.
-.B This is a user\-only option.
+.B This is a user-only option.
.TP
.B SASL_REALM <realm>
Specifies the SASL realm.
-.B This is a user\-only option.

.B SASL_AUTHCID <authcid>
Specifies the authentication identity.
-.B This is a user\-only option.
+.B This is a user-only option.
.TP
.B SASL_AUTHZID <authcid>
Specifies the proxy authorization identity.
-.B This is a user\-only option.
+.B This is a user-only option.
.TP
.B SASL_SECPROPS <properties>
Specifies Cyrus SASL security properties. The
.B TLS_CACERT
is always used before
.B TLS_CACERTDIR.
-This parameter is ignored with GNUtls.
+This parameter is ignored with GnuTLS.
+
+When using Mozilla NSS, <path> may contain a Mozilla NSS cert/key
+database. If <path> contains a Mozilla NSS cert/key database and
+CA cert files, OpenLDAP will use the cert/key database and will
+ignore the CA cert files.
.TP
.B TLS_CERT <filename>
Specifies the file that contains the client certificate.
-.B This is a user\-only option.
+.B This is a user-only option.
+
+When using Mozilla NSS, if using a cert/key database (specified with
+TLS_CACERTDIR), TLS_CERT specifies the name of the certificate to use:
+.nf
+ TLS_CERT Certificate for Sam Carter
+.fi
+If using a token other than the internal built in token, specify the
+token name first, followed by a colon:
+.nf
+ TLS_CERT my hardware device:Certificate for Sam Carter
+.fi
+Use certutil -L to list the certificates by name:
+.nf
+ certutil -d /path/to/certdbdir -L
+.fi
.TP
.B TLS_KEY <filename>
Specifies the file that contains the private key that matches the certificate
.B TLS_CERT
file. Currently, the private key must not be protected with a password, so
it is of critical importance that the key file is protected carefully.
-.B This is a user\-only option.
+.B This is a user-only option.
+
+When using Mozilla NSS, TLS_KEY specifies the name of a file that contains
+the password for the key for the certificate specified with TLS_CERT. The
+modutil command can be used to turn off password protection for the cert/key
+database. For example, if TLS_CACERTDIR specifes /home/scarter/.moznss as
+the location of the cert/key database, use modutil to change the password
+to the empty string:
+.nf
+ modutil -dbdir ~/.moznss -changepw 'NSS Certificate DB'
+.fi
+You must have the old password, if any. Ignore the WARNING about the running
+browser. Press 'Enter' for the new password.

.TP
.B TLS_CIPHER_SUITE <cipher-suite-spec>
Specifies acceptable cipher suite and preference order.
-<cipher-suite-spec> should be a cipher specification for OpenSSL,
-e.g., HIGH:MEDIUM:+SSLv2.
+<cipher-suite-spec> should be a cipher specification for
+the TLS library in use (OpenSSL, GnuTLS, or Mozilla NSS).
+Example:
+.RS

+.TP
+.I OpenSSL:
+TLS_CIPHER_SUITE HIGH:MEDIUM:+SSLv2

.B TLS_RANDFILE <filename>
Specifies the file to obtain random bits from when /dev/[u]random is
not available. Generally set to the name of the EGD/PRNGD socket.
The environment variable RANDFILE can also be used to specify the filename.
