I tried to setup exactly the same things a while ago using the 
radiusplugin for openvpn.
It just don't work! Looking at the code of the radiusplugin I could not 
find anything that handle Sessiontimeout attribute (I didn't tried with 
Acc-Session-Timeout but didn't see anything either).
Even if You try to ack the plugin (which look quite simple), I'm not 
sure openvpn have anymecanism that would allow it to termitate a 
connection after a specified duration (except monitoring connecting 
duration with the telent interface.... a real pain).
I asked on the mailing list of radiusplugin which is even lower traffic 
and gave up. Maybe asking about openvpn being able to disconnect based 
on time  could be a question for start a thread in openvpn general ML.


P.S: I'd be glad to hear about if you succeed in doing that! ;)
