[otrs] Bug with AD and OTRS

Hi, I'am install and configure OTRS at my OpenSuSE 11.1 to use LDAP (Windows 2003 Active Directory). Authenticate work, but if i look for all users (Search "*") i get his names as "Кирилл". So OTRS don't understand russian text from AD. Help me please, how fix this? P. S. Sorry for bad English, i'am from Belarus.
