[Samba] DNS trouble - Join a domain as a DC

[Natália Vaz]

I've tried to join samba a domain as a DC. I've followed Join_a_domain_as_a_DC
How To<http://wiki.samba.org/index.php/Samba4/HOWTO/Join_a_domain_as_a_DC#Check_required_DNS_entries_of_the_new_host>
.
Join domain was successfull, but samba_dnsupdate doesn't work.

samba_dnsupdate --verbose --all-names say dns_tkey_negotiategss: TKEY is
unacceptable

I use bind9.8.
