1 .TH SLAPD-PERL 5 "RELEASEDATE" "OpenLDAP LDVERSION"
4 slapd\-perl \- Perl backend to slapd
14 Any perl database section of the configuration file
16 must then specify what Perl module to use.
18 then creates a new Perl object that handles all the requests for that
19 particular instance of the backend.
21 You will need to create a method for each one of the
25 * new # creates a new object,
26 * search # performs the ldap search,
27 * compare # does a compare,
28 * modify # modifies an entry,
29 * add # adds an entry to backend,
30 * modrdn # modifies an entry's rdn,
31 * delete # deletes an ldap entry,
32 * config # module-specific config directives,
33 * init # called after backend is initialized.
36 Unless otherwise specified, the methods return the result code
37 which will be returned to the client. Unimplemented actions
38 can just return unwillingToPerform (53).
41 This method is called when the configuration file encounters a
44 The module in that line is then effectively `use'd into the perl
45 interpreter, then the \fBnew\fR method is called to create a new
47 Note that multiple instances of that object may be instantiated, as
52 method receives the class name as argument.
55 This method is called when a search request comes from a client.
56 It arguments are as follows:
61 * alias dereferencing policy
65 * attributes only flag (1 for yes)
66 * list of attributes to return (may be empty)
69 Return value: (resultcode, ldif-entry, ldif-entry, ...)
72 This method is called when a compare request comes from a client.
73 Its arguments are as follows.
77 * attribute assertion string
82 This method is called when a modify request comes from a client.
83 Its arguments are as follows.
87 * a list formatted as follows
88 ({ "ADD" | "DELETE" | "REPLACE" },
89 attributetype, value...)...
94 This method is called when a add request comes from a client.
95 Its arguments are as follows.
98 * entry in string format
103 This method is called when a modrdn request comes from a client.
104 Its arguments are as follows.
109 * delete old dn flag (1 means yes)
114 This method is called when a delete request comes from a client.
115 Its arguments are as follows.
123 This method is called once for each perlModuleConfig line in the
126 Its arguments are as follows.
129 * array of arguments on line
132 Return value: nonzero if this is not a valid option.
135 This method is called after backend is initialized.
136 Its argument is as follows.
141 Return value: nonzero if initialization failed.
145 options apply to the PERL backend database.
146 That is, they must follow a "database perl" line and come before any
147 subsequent "backend" or "database" lines.
148 Other database options are described in the
152 .B perlModulePath /path/to/libs
153 Add the path to the @INC variable.
155 .B perlModule ModName
156 `Use' the module name ModName from ModName.pm
158 .B filterSearchResults
159 Search results are candidates that need to be filtered (with the
160 filter in the search request), rather than search results to be
161 returned directly to the client.
163 .B perlModuleConfig <arguments>
164 Invoke the module's config method with the given arguments.
166 There is an example Perl module `SampleLDAP' in the slapd/back\-perl/
167 directory in the OpenLDAP source tree.
171 backend does not honor any of the access control semantics described in
172 .BR slapd.access (5);
173 all access control is delegated to the underlying PERL scripting.
178 pseudo-attribute and to the other attribute values of the entries
181 operation is honored, which is performed by the frontend.
183 The interface of this backend to the perl module MAY change.
184 Any suggestions would greatly be appreciated.
186 Note: in previous versions, any unrecognized lines in the slapd.conf
187 file were passed to the perl module's config method. This behavior is
188 deprecated (but still allowed for backward compatibility), and the
189 perlModuleConfig directive should instead be used to invoke the
190 module's config method. This compatibility feature will be removed at
195 default slapd configuration file
