Multi Domain Setup Kolab 3.1

[User, Kolab]

Hi folks,

I tried to setup multi domain feature with kolab 3.1 on centOS - and 
failed.
I uploaded 
https://github.com/tpokorra/kolab3_tbits_scripts/blob/master/kolab3.1/initMultiDomain.sh 
to my server, changed the file rights to make it executable but I can 
not add new users to a new domain after running the script?!

Can somebody give a hand? Is there a multi domain tutorial 
(step-by-step)?

thanks for your reply. in deed.
