Comment 1 Pedro Sampaio 2023-03-29 15:11:36 UTC 
Created samba tracking bugs for this issue:

Affects: fedora-all [bug 2182777]
Comment 2 Sandipan Roy 2023-03-30 05:04:51 UTC 
The samba package as shipped with Red Hat Enterprise Linux 6, 7, 8 and 9 and Red Hat Gluster is not affected by this issue as Red Hat doesn't provide the AD domain controller capability with it.
