[Remmina-common] Connection being disconnected by Remmina

[Tim <ti...@xe...>]

I am using version 1.1.0 (the most recent available in the repository) 
on a Debian based system (64bit). I log on on to several server using 
RDP  (Win 2003 & 2008) and I am able to stay logged on indefinitely. We 
have a cluster of servers (all 2008R2 64bit) which act as out terminal 
server application servers and I keep being disconnected after being 
idle for around 3 minutes. This does not happen when I log on to the 
same servers on my window PC only when I use my Debian PC and Remmina, 
can you advise is there a setting somewhere that controls idle time out?
