Change MB session logout/timeout?

System

i dont see how to do this in the mediabin admin guides or the enterprise manager. is there a setting in one of the asp files? we would like to increase the period before a user gets booted out of mediabin due to inactivity

checked devnet/docs didnt see anything much besides this thread
