[otrs] LDAP --> Getting "customer User Multivalue attributes"

Hi all, i really have a Problem in configuring the LDAP - Fields in OTRS (2.1.6) So, i ask myself, why i cant get on a multivalue attribute in LDAP-queries have more than the first attribute? I think right, that the cahnges has to be done in Kernel::System::CustomerUser::LDAP? And there at #getCustomer User Info? even if i add a line like if (1==1) {,,,} then the programm wouldnt run anymore, without a change on anything else... could anybody tell me, why this happens??? I am not an perl-Profi, but at least i am very expirences in Programming and can read how to programm things in perl (its not so difficult, i think...) Thx a lot, Greetz Max
