.SH "ABSTRACT"
.IX Header "ABSTRACT"
This extension of the class Net::LDAP::Filter provides entry matching
functionality on the Perl side.
.PP
Given an entry it will tell whether the entry matches the filter object.
.PP
It can be used on its own or as part of a Net::LDAP::Server based \s-1LDAP\s0 server.
.SH "METHOD"
.IX Header "METHOD"
.IP "match ( \s-1ENTRY\s0 [ ,SCHEMA ] )" 4
.IX Item "match ( ENTRY [ ,SCHEMA ] )"
Return whether \s-1ENTRY\s0 matches the filter object. If a schema object is provided,
the selection of matching algorithms will be derived from schema.
.Sp
In case of error undef is returned.
.PP
For approximate matching like (cn~=Schmidt) there are several modules that can
be used. By default the following modules will be tried in this order:
.PP
.Vb 3
\&  String::Approx
\&  Text::Metaphone
\&  Text::Soundex
.Ve
.PP
If none of these modules is found it will fall back on a simple regexp algorithm.
.PP
If you want to specifically use one implementation only, simply do
.PP
.Vb 1
\&  use Net::LDAP::FilterMatch qw(Text::Soundex);
