[Samba] unable to manage users with uermgr

[Ivo Karabojkov]

Hi all!

I have problem adding new user with User manager for domains. When I
click "Add" I got the following message:
This security ID may not be assigned as the primary group of an object
Managing users (setting passwords, profile location, etc.) works fine,
as works adding new machines to the domain.
My OS is FreeBSD 7.1, Samba 3.2, passdb backend is tdbsam and the
configuration is very similar to "secure office network" chapter from
"Samba by Example".

Thanks in advance for your kind cooperation.
