[Samba] Samba 4 dnsupdate errors

I have installed samba from source (I've tried both V4-0-stable and 
v4-1-stable) using BIND9_DLZ on Ubuntu server 13.04 and I'm unable to 
get samba_dnsupdate to function.

# samba_dnsupdate --all-names --fail-immediately

will return

dns_tkey_negotiategss: TKEY is unacceptable

If I then try nsupdate directly:

nsupdate -g /tmp/tmpEk4_WK

I also get:

dns_tkey_negotiategss: TKEY is unacceptable

The credential cache looks like:

# klist -c /tmp/tmpQoCe89

Ticket cache: FILE:/tmp/tmpQoCe89
Default principal: ADS1$@INTERNAL.DOMAIN.COM

DNS/ads1.internal.domain.com at INTERNAL.DOMAIN.COM

Dns appears to be functioning correctly with forward and reverse lookups 

Can anyone help with ideas to track down this problem?
