It seems, secure DNS update has broken in samba. I tried to use different 
versions of samba (3.2.4, 3.4.4, 3.5.4, etc), but always got an error during 
DNS update, in spite of "wbinfo -t" and "net ads info" commands output was OK.

Secure DNS update via nss-update script has sucssefully completed, but it 
requires a domain admin creditionals.
Guys from http://rc.quest.com/topics/ddns/old.php create a patch for nss-
update and GSSAPI library to use machine account instead admin one, but I 
don't try this.

So, I don't promise to disable the secure DNS update, because it decrease AD 

Perghaps, somebody tell us, what we doing wrong?
