This isn't it.  The things after the failure are not the issue, they
are happening in the unwind.  

You can see the real failure in the backtrace, where it fails to find
the records using our DNS client library for LDAP (yes, a very strange
thing). 

As Garming said, the issue is that Samba can't find the DNS records on
your AD DC over LDAP, having just added them via RPC.

This code is a bit tricky, and I thought I had it right, but clearly
that isn't the case.  Garming asked you to see if you could locate
where the records got put the records by hand.  

Thanks,

Andrew Bartlett
