Description Marc Muehlfeld 2013-06-16 20:59:47 UTC
Created attachment 8975 [details]
Debug level 10 output of 'samba_dnsupdate'

- Two DC (both with BIND backend) in the domain
- DC1 (the one with all FSMO roles, etc.) is down
- DC2 uses it's own DNS in resolv.conf

When 'samba_dnsupdate' runs on DC2, in the logs the following appears:
Traceback (most recent call last):
  File "/usr/local/samba/sbin/samba_dnsupdate", line 507, in <module>
  File "/usr/local/samba/sbin/samba_dnsupdate", line 120, in get_credentials
    creds.get_named_ccache(lp, ccachename)
RuntimeError: kinit for DC2$@SAMDOM.EXAMPLE.COM failed (Cannot contact any KDC for requested realm)

I'm not sure, if this is a problem. But maybe the error message can be beautified with a small patch, when you have time. :-)

I re-checked this with 4.5.0rc2: The problem does not exist anymore in this version. I close this bug report.
