[Samba] Samba 3.5 to 3.6

[manfred]

same problem here with a pc not in the same workgroup/domain

we had no problems to access the server with user/password from other workgroup
since update to 3.6.3 - now the user can't access and samba log's the error:

[2012/05/24 15:54:12.124757,  1] auth/server_info.c:391(samu_to_SamInfo3)
  The primary group domain sid(S-1-5-21-133745353-162177866-37141012-513) does
not match the domain sid(S-1-5-21-71619937-141952100-153857936) for
bgsystem(S-1-5-21-71619937-141951100-153857936-4306)

with the correct user/password access to the share should always be granted!
with two windows pc's this would work too.

is there a way to turn the consistency off or switch to the old behavior?
