Comment 1 Pedro Sampaio 2023-03-29 15:06:35 UTC

Created samba tracking bugs for this issue:

Affects: fedora-all [bug 2182773]

Comment 2 Sandipan Roy 2023-03-30 05:04:36 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.
