[Samba] USRMGR.EXE administration: invalid syntax error message

[Karel Kulhavý]

I try to admin Samba 3.0.0 and 3.0.1pre3 (tried both versions) NT4.0
PDC with NT4.0 machine and NT4.0 USRMGR.EXE and get persistent error
message

1) The group name could not be found
2) The user name could not be found
3) The filename, directory name, or volume label syntax is incorrect.

Loggin into domain under name: root

I can see the user and group listing. When I click on a user to see
his details, I get message (2). When I click on a group to see it's details,
I get message (1). When I click on "Add New User" in the menu, I get message
(3).

I have read mailing list postings indicating this works for other people. Am I
doing something wrong? Is there any specification I should read describing
under what circumstances should USRMGR.EXE administration work?

Windows on client: NT4.0 (reinstalled from NT3.5 to NT4.0).
Tried also another NT4.0 box with the same result
Tried also XP box and running NT4.0 USRMGR.EXE -- the same result

Samba: 3.0.0 and 3.0.1pre3 (tried first 3.0.1pre3 and then reinstalled
to 3.0.0 by compiling 3.0.0 and make install 3.0.0 with leaving the same
environment)

Install path: default (./configure without parameters, path defaults
to /usr/local/samba/) Distribution: gentoo.
