[Samba] Samba AD/DC crashed again, third time in as many months

[Sketch]

I'd remove the distro packages providing those libs in /usr/lib, as they 
could possibly cause problems.  One more I forgot, which might possibly be 
responsible for corrupting your ldb database if the wrong one is loaded 
by samba at runtime, is libldb.

>From the log, I'm guessing your database is corrupt if it can't read the 
schema, but someone else might have more insight.
