It seems I just did not restart the winbindd after some crucial change. 
After restarting the service, wbinfo runs as expected.

The rest is supplied as an information for others troubleshooting 
similar issues.

The join failed with the same error on the other system, which is 
running correctly. I investigated that situation and found that the 
error is probably unrelated to the AD DC. I dropped that matter since 
3.6.6 phases out and everything else was running nicely.

It queries the correct DNS and another machine works nicely with this 
DNS. Any other DNS would not resolve the AD DC FQDN in the first place.

As said, Kerberos runs fine. The DNS items of the winbind checklist have 
been verified. BTW: Using the FQDN for didn't work for the 
other system.

root at nfs4:~# net ads join -UAdministrator
Enter Administrator's password:
Using short domain name -- AD
Joined 'NFS4' to realm 'ad.microsult.de'
DNS Update for nfs4.ad.microsult.de failed: ERROR_DNS_INVALID_MESSAGE
DNS update failed!
root at nfs4:~#

So the join is reported as successful, the DNS update failed. But I 
added the machine record manually on the DC. And during the last 
discussion it was claimed that this wasn't even necessary for a client 

So I did not setup nss and PAM so far, which to me makes little sense 
before winbind tools work as expected.

At this point wbinfo must work already!
