Err, slight lapse. Your radius server never has a problem ofcourse.
The problem is that route propagation from your terminal server is
too slow across the network. Coincidentilly, based upon an earlier
post from someone who fixed this with EIGRP, I played some with
OSPF, and indeed by using OSPF across your WAN connections you can
probably solve this problem. It worked for me. EIGRP should work too,
altho it didnt for me.
