[otrs] Customer Groups with LDAP

Hello, I'm trying to use LDAP authentication for customer and agents. So far i've been able to map groups and roles of agents and to authenticate customers and agents. Now i'm trying to map customer groups from LDAP but that doesn't seem to be documented and using $Self->{'UserSyncLDAPGroupsDefination'} seems to just work for agent groups and not for customer groups. I've searched on the list archives and found this with no answer: http://lists.otrs.org/pipermail/otrs/2005-August/008811.html Is there any way to map customer groups from LDAP? If not, how can i create a scenario like the one described in the previous mail but with just one LDAP server? Thanks in advance. Regards.
