Hi Dieter,
There are several things you need to set up on the samba server for AD 
user to have access to it.
* To be in the AD/domain
    - smb.conf with the proper security mode, password server and realm
    - net join the AD
    - make sure the samba machine shows up in the list of trusted 
computers and is properly accessible (DNS and that kind)
    - make sure smbd, nmbd and winbind run
       you can than check the list of users with the command
        $ getent passwd
* To let users access unix services
    - set up nsswitch.conf so passwd and group also use winbind
    - set up pam properly, ie let it use winbind too.
I think this should work. At least that's what the doc says.
I am not really familiar with the error you're getting but it might be 
because you're not using winbind.
Quote from the doc:
"If winbindd is not running, smbd (which calls winbindd) will fall back to
using purely local information from /etc/passwd and /etc/group and no
dynamic mapping will be used."
So make sure winbind is running, the HOWTO explains how to add it to you 
/etc/init.d/samba.
It might vary depending on where you got samba from (official package or 
distribution package).
Chapter 21 is on winbind.
I hope it works out for you.
