ACS 4.0 Authen-Failure-Code

[lunestadr]

Hi,

I'm getting this Authen-Failure-Code in Failed attempts report when I try to authenticate with PEAP against a ACS 4.0:

"Authetication session invalidated"

I'm not able to find ny reference to what this means ? has anyone any info on this and what it points to as a problem?

best regards rolf

Are you trying to authenticate Windows xp clients using PEAP,If so i dont think so it will workout, you have to use Cisco's aironet client utility for PEAP against ACS.
