[Samba] Samba 3.4.7 in Ubuntu 10.04 and WinBindd

[Michael Lueck]

Greetings-

I have sort of fallen out of the loop with major milestones in the Samba project... I was really up on Samba back in the 3.0.x days.

Used to be, a Samba PDC would only run smbd and nmbd tasks. Now I see winbindd tasks as well. I peeked in its log and it does not seem too happy.

Specifically:

failed tcon_X with NT_STATUS_END_OF_FILE
Could not receive trustdoms

Is this normal? Does this mean that by upgrading all the way from Samba 3.0.14a on Debian to 3.3.2 on Ubuntu 9.04, and now with the jump to 3.4.7 on Ubuntu 10.04, is there some setup steps that never 
got done?

Our environment is Samba PDC with a mix of Linux and Window workstations. No Windows servers, no AD, etc...

TIA!

Sincerely,
