[Samba] Samba 3.5.0 and getent group output

[Veiko Kukk]

Hello,

I recently upgraded my testserver Centos 5.4 from sernet samba 
3.3.11-40.el5 to sernet samba 3.5.0-41.el5. Did no configuration 
changes. Samba is configured to get users and groups from NT4 PDC 
through winbind.

Before upgrade to 3.5, 'getent group' returned something like that: 
groupname:x:16777268:user1,user2,user3 etc.
Now it only returns: groupname:x:16777268: without listing members of 
any group.

What might be the problem and how should I fix it?
