So you are running a very EOL version of Samba on a fairly recent 
version of Fedora, why ?

Ah we are getting to the crux of matter here, I would never recommend 
upgrading a self compiled version of Samba in this way. There have been 
instances of files being removed from the version of Samba that you are 
upgrading to, that still exist on disk.
I would recommend setting up a new computer (which may be a VM), 
installing Samba on that and join that to the existing domain, the old 
DC's can then be removed.

That is probably because your method of upgrading Samba has probably 
wiped your database.
