Probably a very silly question, but have you enabled OnConnect as master in the server manager?
The log you show suggests it is not..
Also after you changed settings in OnConnect, it sometimes suggests to restart the 'System auxiliary services'. You may try to do that as well once more.
Also make sure you are at a recent version, I would advise 6.6.2 as an absolute minimum, but better use 6.6.4 if possible. OnConnect is new in 6.6.0 and new features and some fixes came out in the patches.
If that does not resolve your problem, I would ask your Aruba partner, or if you are a partner contact Aruba TAC.
