[Samba] Recognizing trusted domain users

[Karel Kulhavy]

Hello

I am having a Samba 3.0.2 PDC which trusts another domain (served
by NT4 PDC). I would like to make Samba recognize users from the
trusted domain up to the point that
* Permissions could be granted to them to access shares, directories,
  files
* The users from trusted domain can be added into groups on Samba PDC

How can I accomplish this?

I have brought up the trust (it works) but any attempt to assign a
privilege from usrmgr.exe silently fails and any attempt to add a user
from trusted domain into one of Samba's groups fails with "No Such
User".
