[Samba] Problem with user groups

[Gregor Ibic]

I have problem with samba PDC install. I use simple tdb storage.
The problem is in expanding group membership. For example if I log like 
administrator, that is a member of Domain Admins (I checked) on samba, I 
do not get permissions for this role.

I see this in log file

[2005/10/29 15:53:16, 0] 
rpc_server/srv_samr.c:api_samr_query_usergroups(520)
   api_samr_query_usergroups: unable to marshall SAMR_R_QUERY_USERGROUPS.
[2005/10/29 15:53:16, 0] rpc_server/srv_pipe.c:api_rpcTNP(2187)
   api_rpcTNP: samr: SAMR_QUERY_USERGROUPS failed.


I use samba 3.0.20b, but I also tried with other versions, but its the 
same. I also deleted mappings file and recreated mappings several times.
It seems like that when I check on server its ok
(net rpc group members "Domain Admins" -Uroot%pass), but from the client 
fails.
