RADIUSD amnesia!

23 Sep 2008

      I am somewhat confused.

My RADIUS server forgot about some clients, all by itself, honest!

Users stopped being able to authenticate (I say users, we had one!), using eduroam from Portugal, turns out that some time after September 5th, the RADIUS server stopped recognising the JANET roaming RADIUS servers!

I had to restart the servers on September 8th after a failure of our Active Directory servers. RADIUS/Winbind did not recover without help when AD came back. It was the same config however.

There had been a restart on 17th March, 8th Sep and 23rd Sep, so RADIUS was running at the time it developed its amnesia.

-X output attached, with error at the bottom I am seeing when trying to authenticate from off-site.

Anyone got any ideas?
