NAME
slapd-perl - Perl backend to slapd
SYNOPSIS
/etc/openldap/slapd.conf
DESCRIPTION
The Perl backend to slapd(8) works by embedding a perl(1) interpreter into slapd(8). Any perl database section of the configuration file
slapd.conf(5) must then specify what Perl module to use. Slapd then creates a new Perl object that handles all the requests for that par-
ticular instance of the backend.
You will need to create a method for each one of the following actions:
* new # creates a new object,
* search # performs the ldap search,
* compare # does a compare,
* modify # modifies an entry,
* add # adds an entry to backend,
* modrdn # modifies an entry's rdn,
* delete # deletes an ldap entry,
* config # process unknown config file lines,
* init # called after backend is initialized.
Unless otherwise specified, the methods return the result code which will be returned to the client. Unimplemented actions can just return
unwillingToPerform (53).
new This method is called when the configuration file encounters a perlmod line. The module in that line is then effectively `use'd
into the perl interpreter, then the new method is called to create a new object. Note that multiple instances of that object may be
instantiated, as with any perl object. The new method receives the class name as argument.
search This method is called when a search request comes from a client. It arguments are as follows:
* object reference
* base DN
* scope
* alias deferencing policy
* size limit
* time limit
* filter string
* attributes only flag (1 for yes)
* list of attributes to return (may be empty)
Return value: (resultcode, ldif-entry, ldif-entry, ...)
compare
This method is called when a compare request comes from a client. Its arguments are as follows.
* object reference
* dn
* attribute assertion string
modify This method is called when a modify request comes from a client. Its arguments are as follows.
* object reference
* dn
* a list formatted as follows
({ "ADD" | "DELETE" | "REPLACE" },
attributetype, value...)...
add This method is called when a add request comes from a client. Its arguments are as follows.
* object reference
* entry in string format
modrdn This method is called when a modrdn request comes from a client. Its arguments are as follows.
* object reference
* dn
* new rdn
* delete old dn flag (1 means yes)
delete This method is called when a delete request comes from a client. Its arguments are as follows.
* object reference
* dn
config This method is called with unknown slapd.conf(5) configuration file lines. Its arguments are as follows.
* object reference
* array of arguments on line
Return value: nonzero if this is not a valid option.
init This method is called after backend is initialized. Its argument is as follows.
* object reference
Return value: nonzero if initialization failed.
CONFIGURATION
These slapd.conf options apply to the PERL backend database. That is, they must follow a "database perl" line and come before any subse-
quent "backend" or "database" lines. Other database options are described in the slapd.conf(5) manual page.
perlModulePath /path/to/libs
Add the path to the @INC variable.
perlModule ModName
`Use' the module name ModName from ModName.pm
filterSearchResults
Search results are candidates that need to be filtered (with the filter in the search request), rather than search results to be
returned directly to the client.
EXAMPLE
There is an example Perl module `SampleLDAP' in the slapd/back-perl/ direcetory in the OpenLDAP source tree.
WARNING
The interface of this backend to the perl module MAY change. Any suggestions would greatly be appreciated.
