yes, I'm looking at it , i believe, the right way around - I have a remote
RADSEC client talking to this server - so that remote server is a client...

this is a straight forward cert that has been signed by the eduPKI system - 
no chained certificate IIRC  (though a chained CA shouldnt be an issue either
as many clients are signed by a CA that is chained to a CA....)

I've removed some things for privacy/security...and other bits because I'm not too familiar
with eduPKI policy on disclosure - eg OID policies...
