[Samba] more cleanup: mis-named AD user

[Stefan G. Weichinger]

The saga around the misnamed DC seems over, so let's open a new thread ;-)

In the same AD I see this:

in smbstatus I see a smbd-PID for a Username "root", Group "root"

But the actual user logged in is another one. So I assume there has been
some wrong mapping/naming in the past.

I don't think that user actually runs with root-privileges or so ...
it's just ugly and wrong and I'd like to clean that up as well, if possible.

For sure I'd like to avoid deleting/recreating that user.

Any ideas how to approach this?
