.SH NAME
|
|
slapd\-perl \- Perl backend to slapd
|
|
.SH SYNOPSIS
|
|
/etc/openldap/slapd.conf
|
|
.SH DESCRIPTION
|
|
The Perl backend to
|
|
.BR slapd (8)
|
|
works by embedding a
|
|
.BR perl (1)
|
|
interpreter into
|
|
.BR slapd (8).
|
|
Any perl database section of the configuration file
|
|
.BR slapd.conf (5)
|
|
must then specify what Perl module to use.
|
|
.B Slapd
|
|
then creates a new Perl object that handles all the requests for that
|
|
particular instance of the backend.
|
|
.LP
|
|
You will need to create a method for each one of the
|
|
following actions:
|
|
.LP
|
|
.nf
|
|
* 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.
|
|
.fi
|
|
.LP
|
|
Unless otherwise specified, the methods return the result code
|
|
which will be returned to the client. Unimplemented actions
|
|
can just return unwillingToPerform (53).
|
|
.TP
|
|
.B new
|
|
This method is called when the configuration file encounters a
|
|
.B perlmod
|
|
line.
|
|
The module in that line is then effectively `use'd into the perl
|
|
interpreter, then the \fBnew\fR method is called to create a new
|
|
object.
|
|
Note that multiple instances of that object may be instantiated, as
|
|
with any perl object.
|
|
.\" .LP
|
|
The
|
|
.B new
|
|
method receives the class name as argument.
|
|

|
|
.SH CONFIGURATION
|
|
These
|
|
.B 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
|
|
.BR slapd.conf (5)
|
|
manual page.
|
|
.TP
|
|
.B perlModulePath /path/to/libs
|
|
Add the path to the @INC variable.
|
|
.TP
|
|
.B perlModule ModName
|
|
`Use' the module name ModName from ModName.pm
|
|
.TP
|
|
.B 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.
|
|
.SH EXAMPLE
|
|
There is an example Perl module `SampleLDAP' in the slapd/back\-perl/
|
|
directory in the OpenLDAP source tree.
|
|
.SH ACCESS CONTROL
|
|
The
|
|
.B passwd
|
|
backend does not honor any of the access control semantics described in
|
|
.BR slapd.access (5);
|
|
all access control is delegated to the underlying PERL scripting.
|
|
Only
|
|
.B read (=r)
|
|
access to the
|
|
.B entry
|
|
pseudo-attribute and to the other attribute values of the entries
|
|
returned by the
|
|
.B search
|
|
operation is honored, which is performed by the frontend.
|
|
.SH WARNING
|
|
The interface of this backend to the perl module MAY change.
|
|
Any suggestions would greatly be appreciated.
