Ok, thx. Nothing for us with Win AD servers.

The Doamin Users Group does have a seperate gid and thats the primary
group for all users, which all users do have set as gid.

Yeah, thats the strange part.It did work with the AD config until we did
clean up (remove accounts), disable SMBv1 and chanbge KrbTGTKLey.
So we did not change any UID oder GID.
And even if, as I did read the above thread correct, a UID and GID in
range for any user should be enough to work, but it does not for any
user, except the admins.
And thats strange.
testparm -s shows like smbconf. correct network, smbv2 protocol, idmap
ranges as expected.
Do we need seperate user/group ranges in samba config?
