Description

What were you trying to do that didn't work?

After finishing Linux Virtual Delivery Agent setup, when we tried to launch a remote gnome desktop, the desktop couldn't work:

Then we found many service activation failures in /var/log/messages as following

Please provide the package NVR for which bug is seen:

samba-winbind-modules-4.18.6-101.el9_3.x86_64

How reproducible:

Steps to reproduce

Make sure SELinux is enabled or permissive(Only when SELinux is disabled, this issue won't occur)
Make sure machine has joined domain by winbind and samba
Make sure samba-winbind has been upgraded to 4.18.6(4.17.5 works fine)
launch a remote gnome desktop(Launching a local desktop won't cause this issue.)

Expected results

Remote gnome desktop works fine

Actual results

Remote gnome desktop cannot work
