Dear Samba-Team,

I have the following problem:
The smbd and winbindd start fine, everthing seems to be okay, all users can be
authenticated.
The getent passwd command for every user in the WIN Domain SUED looks good.
The users are granted in their shares very well.

But a few minutes later, the winbindd is suddenly unable to authenticate some
users against the Domain. You can see it in the snapshot. Messages like "Unable
to initgroups" or "make_server_info_info3: pdb_init_sam failed!" don't look fine.

I tried it with samba3.0.1.pre3 and samba3.0.1rc1

 Here a snapshot of the log.smbd

Now the getent passwd SUED+Ringer.Thomas cannot be resolved.

After a restart of the winbindd everything is okay again, but not very long,
other users cannot acces to their share.
