Login from Workstation not possible anymore

[Frank Weißer <linux@weisser-ol.de>]

Hi all,
after doing apt upgrade I restarted my tjener to get changes on 
linux-image* running

frank@tjener:~$ cat /etc/debian-edu/config
# Generated by debian-edu-profile-udeb
VERSION="9+edu0"
PROFILE="Main-Server, Workstation, LTSP-Server"
LANGCODE="de"
LOCALE="de_DE.UTF-8"
frank@tjener:~$ cat /etc/debian_version
9.11

Now I no longer can login from my workstation. Starting the same PC as 
ThinClient or Diskless Workstation login works,

Workstation seems to not mount /skole/tjener/home0 but it mounts /skole.

I also tried a new pxe-install with same results.

Any hints are appreciated
