I will try to wipe /var/cache/samba later today, maybe we pull allong
some old stuff in some old files (I see files from 2016 in there !?)

Additional qs:

as it seems to be one user only with this problem ->

is there a way to re-create an AD user and keep its SID/RID/whatever is
needed to make sure that the windows user profile doesn't have to be
re-created as well?
