package Fripost::Schema::Local;
=head1 NAME
Local.pm -
=head1 DESCRIPTION
Local.pm abstracts the LDAP schema definition and provides methods to
search for virtual users, aliases or lists alltogether.
=cut
use 5.010_000;
use strict;
use warnings;
use utf8;
use parent 'Fripost::Schema';
use Fripost::Schema::Util qw/concat split_addr canonical_dn/;

use Net::LDAP::Util 'escape_filter_value';
=head1 METHODS
=over 4
=item B<get> (I<local>, I<OPTIONS>)
Returns a hash with all the (visible) attributes for the given entry. An
additional 'type' attribute gives the type of *the* found entry
(possible values are 'user', 'alias', and 'list').

Returns 1 if the given I<local>@I<domain> exists, and 0 otherwise.
The authenticated user needs to have search access to the 'entry'
attribute.

=head1 GLOBAL OPTIONS
If the B<-concat> option is present, it will intersperse multi-valued
attributes. Otherwise, an array reference containing every values will
be returned for these attributes.
The B<-die> option, if present, overides LDAP croaks and errors.
