[otrs] Problem with few CustomerUser storages

Hello ! We have three configured CustomerUser storages : $Self->{CustomerUser} = { Name => 'Database', Module => 'Kernel::System::CustomerUser::DB', Params => { ... $Self->{CustomerUser1} = { Name => 'LDAP', Module => 'Kernel::System::CustomerUser::LDAP', ... $Self->{CustomerUser2} = { Name => 'Database2', Module => 'Kernel::System::CustomerUser::DB', ... In Customer User search and edit form ( http://otrs.pk.ru/otrs/index.pl?Action=AdminCustomerUser&Nav=Agent ) we can perform complex search (sequentally in all three storages), but we can't separate results by any source storage. Any selections by popup list has no effect.
