SLAPD-PERL(5)                          File Formats Manual                          SLAPD-PERL(5)



NAME
       slapd-perl - Perl backend to slapd

SYNOPSIS
       /etc/ldap/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 particular 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     # module-specific config directives,
         * 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 dereferencing 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 once for each perlModuleConfig line in the slapd.conf(5) con‐
              figuration file.  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 subsequent "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.

       perlModuleConfig <arguments>
              Invoke the module's config method with the given arguments.

EXAMPLE
       There  is  an  example  Perl  module `SampleLDAP' in the slapd/back-perl/ directory in the
       OpenLDAP source tree.

ACCESS CONTROL
       The perl backend does  not  honor  any  of  the  access  control  semantics  described  in
       slapd.access(5);  all  access control is delegated to the underlying PERL scripting.  Only
       read (=r) access to the entry pseudo-attribute and to the other attribute  values  of  the
       entries returned by the search operation is honored, which is performed by the frontend.

WARNING
       The  interface  of  this  backend  to  the  perl module MAY change.  Any suggestions would
       greatly be appreciated.

       Note: in previous versions, any unrecognized lines in the slapd.conf file were  passed  to
       the  perl module's config method. This behavior is deprecated (but still allowed for back‐
       ward compatibility), and the perlModuleConfig directive should instead be used  to  invoke
       the  module's  config  method.  This  compatibility feature will be removed at some future
       date.
