Hi, Stefan,

I think you have something set up incorrectly, or you are connecting to a DC, or something changed after Samba 4.17.8

I can logon using ssh with kerberos to a Unix domain member running on bookworm (Samba 4.17.8)

rowland at devstation:~$ ssh rowland at TESTDM12.SAMDOM.EXAMPLE.COM
Creating directory '/home/rowland'.
Linux testdm12 6.1.0-9-amd64 #1 SMP PREEMPT_DYNAMIC Debian 6.1.27-1
(2023-05-08) x86_64

The programs included with the Debian GNU/Linux system are free software; the exact distribution terms for each program are described in the individual files in /usr/share/doc/*/copyright.

If I run 'id' I get this:

rowland at testdm12:~$ id rowland at samdom.example.com
uid=11104(rowland) gid=10513(domain users) groups=10513(domain users),11104(rowland),10512(domain admins),10572(denied rodc password replication

and running 'ls' against my home directory gets this:

rowland at testdm12:~$ ls -la /home/rowland total 32 drwxr-xr-x 3 rowland domain users 4096 Jun 17 12:12 .
drwxr-xr-x 4 root    root         4096 Jun 17 12:12 ..
-rw-r--r-- 1 rowland domain users  220 Jun 17 12:12 .bash_logout
-rw-r--r-- 1 rowland domain users 3526 Jun 17 12:12 .bashrc

-rw-r--r-- 1 rowland domain users  807 Jun 17 12:12 .profile

No 'DOMAIN' anywhere.
