[Samba] Internal DNS strangeness in 4.1.16

[Greg Dickie]

Hi,

  I have just provisioned a new samba setup with 2 DCs running ISC DHCPd in failover and I’m trying to get it to play nice with samba internal DNS but I’m having some issues.

1) I’m using on commit, etc triggers in the dhcpd config to call a script that calls samba-tool to add, delete or update DNS. This script works fine when I call it from the command line as the dhcpd user but when called from the dhcpd daemon it throws a WERR_INTERNAL_DB_ERROR which is scary. That is coming from the client I guess. What is the best way to figure out what is going on server side. I increased the log level but I get crazy amounts of info that does not seem relevant.

2) I added a reverse zone 80.16.172.in-addr.arpa and when I add records to it all lookups fail with samba saying it’s not authoritative for the lookup.I figured maybe it was a class B vs Class C thing so I created a 16.172.in-addr.arpa zone and tried that. It’s better, now I just get a SERVFAIL like it can’t find it. If I do a samba-tool query ALL I see records in the AD.

I haven’t played with 4 since the early days, it’s come a long way. nice. 

Any ideas for the problems above?

Thanks,
Greg
