Hi Denis, the problem is that it isn't really a Samba bug, but if it is
a bug, it has been fixed in 4.16.0 , so if you do open a bug report, it
will probably get closed very quickly.
I would imagine that backporting Heimdal 8.0pre was considered but
rejected because it isn't a maintenance or security problem and would
probably require multiple other changes, but I am guessing here.
As for upgrading Samba, I keep saying that users should try to keep up
with the latest samba, this is because Samba is rapidly evolving and
using old versions of Samba in a domain is not advised.
