real world radsec example

[Alex Sharaz]

Hi,
Has anyone got a real world RADSEC example between two FR 3.0.[89] servers they would be prepared to share ? Having a bit of trouble getting this to work. 

I've successfully got FR 2.2.7 -> radsecproxy 1.6.x -> FR 3.0.9 working ( tested using radtest -> FR 2.2.7 ) but am having a bit of a problem either going from FR 3.x-> radsec proxy  or FR 3.x <--> 3.X

On the server I'm running radtest on I get 

Mon Jul 20 14:03:14 2015 : Debug: (0) proxy: Trying to open a new listener to the home server
Mon Jul 20 14:03:14 2015 : Debug: Opening new proxy socket 'proxy (0.0.0.0, 0) -> home_server

and I really can't see why I'm getting the unknown CA error. Certainly shouldn't be a self signed cert anywhere.
