slapd-perl - Perl backend to slapd
ETCDIR/slapd.conf
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) configuration 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.
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.
There is an example Perl module `SampleLDAP' in the slapd/back-perl/
directory in the OpenLDAP source tree.
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.
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 backward 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.
