[Samba] Limit user groups

[Bruno Guerreiro]

Hello,
I'm trying to add a user to big list of Samba groups, 74 groups to be
precise.
The problem is that when the user reaches around 65 to 70 groups, it starts
giving errors in User Manager for Domains, and causes a panic in Samba.
Is there a limit for how many groups a user may belong?
I'm using Samba-3.0.10 with openldap.

This is what I get in the logs.
