Zimbra ldap auth

[saturn]

Hello,

Is there a way to authenticate any applications with zimbra openldap (like apache..) by groups ?
The problem is i can't affect more the one posix group to user
I use zimbra 5 RC2.
Thank's for your help.

Did you try the wiki? Specifically these articles:

UNIX and Windows Accounts in Zimbra LDAP and Zimbra Admin UI - Zimbra :: Wiki
Extending Admin UI - Zimbra :: Wiki

Yes i do, but i don't find how to add multiples posix groups to one user..

So i try to use distribution lists but visibly i can't query this on openldap.
