We have a V2110 Controller set up to do authentication with RADIUS to our AD server using MSCHAP v2. But it suddenly stopped working.
In the log on the AD server I can see this many times in application log:
Negotiation failed. No available eap methods.
It never appeared before it was working and now it's showing that error a few times every minute.
I tried duplicating the Network Policy, disabling the old one and renaming the new one to the old ones name. But no luck.
Anyone else bump in to this?
