NAME

Net::LDAP::FilterMatch - LDAP entry matching

SYNOPSIS

  use Net::LDAP::Entry;
  use Net::LDAP::Filter;
  use Net::LDAP::FilterMatch;

  my $entry = new Net::LDAP::Entry;
  $entry->dn("cn=dummy entry");
  $entry->add (
   'cn' => 'dummy entry',
   'street' => [ '1 some road','nowhere' ] );

  my @filters = (qw/(cn=dummy*)
                 (ou=*)
                 (&(cn=dummy*)(street=*road))
                 (&(cn=dummy*)(!(street=nowhere)))/);


  for (@filters) {
    my $filter = Net::LDAP::Filter->new($_);
    print $_,' : ', $filter->match($entry) ? 'match' : 'no match' ,"\n";
  }

ABSTRACT

This extension of the class Net::LDAP::Filter provides entry matching functionality on the Perl side.

Given an entry it will tell whether the entry matches the filter object.

It can be used on its own or as part of a Net::LDAP::Server based LDAP server.

METHOD

match ( ENTRY [ ,SCHEMA ] ): Return whether ENTRY matches the filter object. If a schema object is provided, the selection of matching algorithms will be derived from schema.
In case of error undef is returned.

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:

  String::Approx
  Text::Metaphone
  Text::Soundex

If none of these modules is found it will fall back on a simple regexp algorithm.

If you want to specifically use one implementation only, simply do

  use Net::LDAP::FilterMatch qw(Text::Soundex);
