I will try with a Win 10 machine, but, 'local user SID' ? A local user
on a Samba Unix domain member will either be a Windows user with a
uidNumber (in which case it will be the domain SID) or it will be a
local Unix user and there will not be a SID.
I wonder if the 'unresolved SID' could be one of the Well Known SIDs ?

Good to know.

The thing is, without knowing what the 'specific circumstances' are, it
is hard to fix the problem, is it any file/folder or just a specific
type e.g. .xls
