[otrs] Active Directory integration charset

Hi list, I've setup Otrs 2.1.1 with active directory integration. Integration works fine, but in french, I've a problem with special caractères like this : Assistante Création / Transmission in place of Assistante Création / Transmission I've tried a solution in http://bugs.otrs.org/show_bug.cgi?id=1056, changing charset in Config.pm to utf-8 does'nt work. Any Ideas ? Is it a bug ? Thanks Olivier BATARD Service Informatique CMALA Tel : 02 51 13 83 74 TP : 06 79 66 17 29
