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...

Here is the DC's smb.conf:

         bind interfaces only = Yes

         path = /var/lib/samba/sysvol/samdom.example.com/scripts

Nothing wrong there

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

Samba is running on (Arch) Linux with Kernel 4.11. Clients are
Windows 10 with all the latest updates, I'm running the RSAT from

In which case you will not have 'Unix Attributes' tab in ADUC.
