Domain users : no connection possible

[peterGO]

NoMachine version(s) 8.1.2  (free) both on client and server
Server: Ubuntu Desktop 22.04.1 LTS

Client MacOS 12.6.1

Server display manager : /usr/sbin/gdm3

Both server and client are on same network, and both in the same active directory domain
A domain user admin-xyz has already logged into the Linux system – so his home directory is loaded and he was able to access the system from the console.

However, when trying to connect using NoMachine with username: domain\admin-xyz  and domain password, Authentication fails each time.

In nxerror.log  file :

5631 5631 14:45:56 070 nxexecPAMCheckCredentials: ERROR! Account validation failed.

5631 5631 14:45:56 070 nxexecPAMCheckCredentials: Error code ‘6’, ‘Permission denied’.

Info: Connection from 10.21.0.101 port 56469 closed on Wed Oct 26 14:45:56 2022.

Info: Handler with pid 5247 terminated on Wed Oct 26 14:45:56 2022.

Info: Handling connection from 10.21.0.101 port 56473 on Wed Oct 26 14:45:56 2022.

Is there a detailed guide on how to enable AD users ?

I noticed others requesting similar question, but the suggestions there did not work for me and I even ended up with an unstable machine that required re-installing

Hi, please take a look at the article in our knowledge base:

Connecting with NX protocol to a NoMachine server on Linux in an Active Directory domain
https://kb.nomachine.com/AR12P01007

Does it help?

I’m not sure which topics you are referring to, perhaps this one https://forums.nomachine.com/topic/nx-linux-sssd-ad-issues-with-nfs4-kerberos-home-dir which is currently being investigated. At a glance yours looks to be different.

Hi Britgirl,
Many thanks for your fast reply!
Will check the link you provided – looks rather well explained at first sight. Currently I’m trying to finish plenty of other tasks before a long weekend. I’ll certainly look into this later (next week hopefully)  and get back with findings.
