[Samba] New AD user cannot access file share from member server

I missed to mention it. But I actually did try changing the CN=users to
OU=ouname, and even leaving it out. I don't know why it didn't return
any
results before, it does now - see my reply to James.

[Samba] New AD user cannot access file share from member server

Not sure if it matters but here is the AD object of a user with no issues:

[root at GJSERVER ~]# ldbsearch -H /var/lib/samba/private/sam.ldb -b
'ou=office,dc=samdom,dc=example,dc=ch' -s sub

Except for the fact that the attributes are not in the same order, I can't
seem to find a relevant difference.

That might be the problem, who did you create first ?
John Doe or Jane Doe ?

I only ask this because they both seem to have this:

CN=John Doe,OU=OFFICE,DC=samdom,DC=example,DC=ch
homeDirectory: \\fileserver\users\jd

CN=Jane Doe,OU=OFFICE,DC=samdom,DC=example,DC=ch
homeDirectory: \\fileserver\users\jd

They both cannot own the users directory 'jd' or is this a sanitisation
error ?
