[otrs] LDAP and Multigroup

Hello, I'm currently in the process of deploying an otrs system, and I found that I could use our already set up ldap server for user and customer authentification, along with customer data. That's already quite nice. But is there a way to use the "ou" field of the ldap entries to affect users "automagically" to the correct group (each group would be a predefined department like IT, sales...), and make this work in a multi-group setup ? This way all employees would be "users", but only in their department, and customer of all others... If it needs a little programming, I'm ready to begin that, but I first need to know if it is feasible... Thanks in advance -- Xavier Scolard
