Fri Nov 24 22:32:31 UTC 2017

Hi Rowland!

I've uninstalled the samba packages and their dependencies, and now
the error is:

Nov 24 23:29:16 testdc1.mytestdom.testsamba.com named[9501]:
samba_dlz: Failed to connect to /usr/local/samba/private/dns/sam.ldb

Nov 24 23:29:16 testdc1.mytestdom.testsamba.com systemd[1]:

I have also messed up the permissions on /usr/local/samba. :-S
Would it make more sense to reprovision?
