SSL VPN Up an down Scripts

I had 3 Linux boxes where i now have 3 astaros in use. About 30 Users had openVPN Access before. In the config directory they had up- und down Scripts where they logged in their Domain and mapped Network drives.
Now with astaro SSL VPN Client and the new config files, the up and down Scripts throws exit=1 error (according to the end user).
What is diffent to openvpn now. openvpn Version was 2.1beta
