I've not seen an error like yours before. It suggests one of the key
objects that the KDC needs to start is not present in the DB.
This particular error is pretty damming:

That is, it can't find the base object for the whole domain.
What does 'samba-tool dbcheck' say? After a backup, does running it
with --fix resolve the issue or at least run clear?
If that is fixed (somehow), then what does 'samba-tool domain
exportkeytab' or 'pdbedit -L -v' say? Try turning up the debug level
to get a failure message if it fails.
But all said and done, it seems unlikely that that domain is in a
'good' enough state to continue.
