One thing you forgot to perform before you turned off your Samba 4 DC
was to transfer the FSMO roles. Since you've powered off your existing
Windows AD DC, the only way to repair it is to seize the RID Master to
the samba 4 DC as the Samba 4 DC can't seem to figure out where the
appropriate RIDs are.

If you can't... well, sorry but you really hosed the domain entirely.
