Hello @all:


Calling DNS Update results in this failure:


root at samba01:/# samba_dnsupdate --all-names

Traceback (most recent call last):

  File "/usr/sbin/samba_dnsupdate", line 784, in <module>

    creds = get_credentials(lp)

  File "/usr/sbin/samba_dnsupdate", line 141, in get_credentials

    ans = check_one_dns_name(sub_vars['DNSDOMAIN'] + '.', 'NS')

  File "/usr/sbin/samba_dnsupdate", line 251, in check_one_dns_name

    ans = resolver.query(name, name_type)

  File "/usr/lib/python2.7/dist-packages/dns/resolver.py", line 912, in


  File "/usr/lib/python2.7/dist-packages/dns/resolver.py", line 143, in

    raise NoAnswer



I'm stuck at that point currently. Updates via samba-tool work, but not via
kerberos or samba it self:
