Re: [Samba] `getent passwd` not working with ad backend

I added uid/gid to the new users and groups. I dont have access to ADUC so can't check atm.

Here's how I added new group:

`samba-tool group add lag --gid-number 16000 --nis-domain SAMDOM`

Here's how I added new user:

`samba-tool user create user23 --unix-home=/home/%U --uid-number=14800 --login-shell=/bin/bash --gid-number=16000 --nis-domain SAMDOM`

On the DC, I checked the new user:

root@DC1 # getent passwd user23

SAMDOM\user23:*:14800:12000::/home/SAMDOM/user23:/bin/bash

But I noticed that although I set the gid of user23 to be 16000, the gid reported by `getent passwd user23` is 12000 (gid of Domain Users). A little digging in the sam.ldb file says that the primaryGroupID is still 513. Could this be causing any problem?

No output with this command too.

I set it only for testing. I'll disable it once I move it to production.
