"Authetication session invalidated" via Radius / ACS

Hi folks.

I get these messages a lot from my ACS 4.0 box. Note the typo: authetication vs authentication. This typo is "in" the ACS messages, and even some Cisco documentation (but doesn't say what the error means)

I think the error is related to wireless PEAP auth.

Re: "Authetication session invalidated" via Radius / ACS

Did you ever resolve this? How?

I have the same error on a 4.2 trial version, using PEAP. EAP-TLS works just fine however. Strange.
