[Samba] samba-tool domain schemaupgrade fails on DC member
garming at catalyst.net.nz

This is a known issue:
There are currently patches in master to fix this issue. We could
probably backport a patch to 4.10, but you'd have to rebuild Samba.
Alternatively, re-joining the domain controller (or joining a new DC and
demoting the old one) probably works because I believe there is code to
handle this case.
There's not really any rollback of this code besides keeping a backup.
Schema updates build on top of each other and once you're at a certain
level you can't undo them, neither on Windows.
