[Samba] Samba 3.0.2 user group problem

[Chu, Dan]

It seems that Samba 3 has changed the user group behavior. We have users who belong to 15 different groups in Solaris and Samba 2.2.6 worked fine for those users. But after migrating to Samba 3.0.2, those users can no longer connect to Samba server unless we reduce the number of groups to about 11. Is this a known issue or expected behavior? If so, what's the solution without reducing the number of groups that users belong to? 

Thanks in advance.
