Public bug reported:

Starting from a working samba (2:4.13.17~dfsg-0ubuntu1.20.04.2) AD on
Ubuntu focal with "server role = active directory domain controller" and
windows 10 computers joined to domain, users in samba can authenticate
on windows sessions.

1. Upgrade samba packages to 2:4.13.17~dfsg-0ubuntu1.20.04.4
2. Reboot windows computers
3. Create a new user in samba
4. Authentication fails on windows with created account

Note : if packages are downgraded to version
2:4.13.17~dfsg-0ubuntu1.20.04.2 and windows is reboot, authentication
works again. All the steps (upgrade and downgrade) have been reproduced
on several and separated Ubuntu focal servers with several Windows 10
computers (22H2 or 21H2) with same behavior.

** Affects: samba (Ubuntu)
