That did the trick...
* robb slaps himself not noticing the difference between ebox-usercorner and zentyal-usercorner
for the non techies:
- open a terminal console
- type: 'sudo nano /etc/passwd' (without quotes)
find the line 'ebox-usercorner:x:xxx:xxx::/var/lib/ebox-usercorner/:/bin/false'
change that line in: 'ebox-usercorner:x:xxx:xxx::/var/lib/zentyal-usercorner/:/bin/false'
to save the file: 'ctrl o' (hit control o at the same time)
to exit nano editor: 'ctrl w' (hit control and w at the same time)
restart zentyal usercorner module:
'sudo /etc/init.d/zentyal usercorner restart' and hit return (and Bob's your uncle...
)
after that you can enter the usercorner by going to https://<address of zentyal>:8888
port 8888 is the default port. If you have ever changed that use the changed port number.
