Forgot about that :-(

(In my configure script, the director ssh's to the RIP and 
checks that the demon is running on the VIP).

sorry I don't get the point here.

I'm pretty much out of ideas. Is this a radius problem or an 
ldirectord problem? ie can you setup a single director (no 
ldirectord) by hand and have it loadbalance two radius 
realservers?
