Startup errors when DNS/[primary-dc].[domain] on [primary-dc]$ spn exists

[Michael Croes]

Hi all,

Friday I updated my Samba 4 DC to Samba 4.0.4. I also went from Bind DLZ to
internal DNS at the same time. Now whenever I start Samba I will get the
following log entries and a useless (bunch of) samba process(es):

[2013/03/25 12:38:52,  0] ../source4/smbd/server.c:475(binary_smbd_main)
  samba: using 'standard' process model
[2013/03/25 12:38:52,  0]
../source4/smbd/service_task.c:35(task_server_terminate)
  task_server_terminate: [Failed to obtain server credentials for DNS,
despite finding it in the samdb! NT_STATUS_CANT_ACCESS_DOMAIN_INFO
  ]
[2013/03/25 12:38:52,  0] ../source4/smbd/server.c:210(samba_terminate)
  samba_terminate: Failed to obtain server credentials for DNS, despite
finding it in the samdb! NT_STATUS_CANT_ACCESS_DOMAIN_INFO

Now if I do samba-tool spn delete DNS/[primary-dc].[domain] [primary-dc]$
it will start up, and immediately the spn entry is there again as well. At
this point, a restart will result in a non-working state again, until I
delete the spn and restart again.

I did a ldap-search for DNS/*, and the only one that shows up is the SPN
for the primary DC (which is my only DC as well right now).

Also, I don't have any dns-[host] accounts anymore, but I guess they're not
used in conjunction with the internal DNS server, but I couldn't find any
details on this.

Please let me know if I should provide more information or if I should
apply any patches in order to get help.
Regards,

Michael
