That's correct, I don't have "Unix Attributes" but through the
advanced view I have access to all attributes.

The ldbsearch command is not returning anything in my case, it
gives me 0 records - no matter which user I try, even the
Administrator. I checked the
command several times to make sure there are no typos. I even
changed the objectclass from "person" to "user" to see if it makes
any difference but it doesn't.

I tried borth /var/lib/samba/sam.ldb
and /var/lib/samba/private/sam.ldb) and the environment
environment has LDB_MODULES_PATH set.

I can easily look at the objects using the ADUC from the RSAT, not
sure why
this isn't working...

Nothing wrong there

I'm not sure what you mean by showing you the user's AD object,
you elaborate?

OK, install ldb-tools if not installed, then run this:

ldbsearch -H /usr/local/samba/private/sam.ldb -b
'cn=users,dc=samdom,dc=example,dc=com' -s sub

Just in case it has got split up over multiple lines, the above
should just one line.

/usr/local/samba/private/sam.ldb with the path to your sam.ldb

dc=samdom,dc=example,dc=com with your dns/realm names

rowland with your users name

You should get something like this back:

Please post that, though you can sanitise it if you like, but if
you do, use the same changes through out.

Windows 10 with all the latest updates, I'm running the RSAT from

Rowland was linking to the CN=users. Yours may not be located there.

I could swear I tried this before, too, but it didn't give me any

one entry and 3 referrals.

OK, glad we got that sorted out ;-)

Your user 'Jane Doe' does not have a 'gidNumber' attribute, does
'Domain Users have a 'gidNumber attribute' ?

It does, it's set to 10001.

And none of the users have gidNumber set.

Is the users Primary group name/GID set as 'Domain Users'?
