groups from users for display purposes

=cut

sub LimitToUsers {
    my $self = shift;

    my $principals = $self->NewAlias('Principals');
    $self->Join( ALIAS1 => 'main', FIELD1 => 'MemberId',
                 ALIAS2 => $principals, FIELD2 =>'id');

    $self->Limit(       ALIAS => $principals,
                         FIELD => 'PrincipalType',
                         VALUE => 'User',
                         ENTRYAGGREGATOR => 'OR',
                         );
}




=head2 LimitToGroups

Limits this search object to Groups who are members of this group.
This is really useful when you want to have your UI separate out
groups from users for display purposes

    $self->Join( ALIAS1 => 'main', FIELD1 => 'MemberId',
                 ALIAS2 => $principals, FIELD2 =>'id');

    $self->Limit(       ALIAS => $principals,
                         FIELD => 'PrincipalType',
                         VALUE => 'Group',

of the group which has PRINCIPAL_ID as its principal id.

=cut

sub LimitToMembersOfGroup {
    my $self = shift;
    my $group = shift;

    return ($self->Limit( 
                         VALUE => $group,
                         FIELD => 'GroupId',
                         ENTRYAGGREGATOR => 'OR',
