[X2go-User] Problem Using Cloned Accounts

Hi ted,

have you checked that the default bash for your new users is /bin/bash. 
In recent distribution, /bin/sh is a symlink to dash for performance 
reason (it is a striped down shell), and it is not compatible with x2go. 
I had this issue a few times already.

Hope this help,

Denis
