[Samba] DNS Update fails

[Viktor Trojanovic]

I just did some work on a member server and decided to leave and rejoin 
the AD. The rejoin worked out fine but I received an error message with 
regards to a failed DNS update.

Following the wiki, I ran  samba_dnsupdate --verbose --all-names on the 
DC, but I'm getting only errors. The last lines read:

; TSIG error with server: tsig indicates error
update failed: NOTAUTH(BADSIG)
Failed nsupdate: 2
Failed update of 29 entries

I'm generally having some problems on this AD so this might be part of a 
bigger story. However, those problems are still very minor, not 
disrupting day to day functionality.
