[Samba] function level Raising 2012R2 still not working

[Daniel Müller]

Hello to all,

I have samba 4.17.10 running. When I try to raise funtion level to:
samba-tool domain level raise --domain-level=2012_R2
ERROR: Domain function level can't be higher than the lowest function level
of a DC!
There is still the error as years ago.
Are we still working on status function level 2008?
Or is there a way to raise the level meanwhile?

Greetings
Daniel
