Communication problem between a lan enforcer and a NPS
I have an issue regarding communications between a lan enforcer i am setting up and a Microsoft RADIUS server (NPS).
The lan enforcer forwards the radius packets to the NPS but it never answers it. Instead I keep having this message in the NPS event logs:
"An Access-Request message was received from RADIUS client x.x.x.x with a message authenticator attribute that is not valid." (event id 18)
When i check the debug kernel on the lan enforcer, the radius requests time out and I get "unavailable" as a result for the authentication.
I already checked the secret many times.
I have installed a sniffer on the nps. I see the requests from the lan enforcer but no answer is sent.
I do not know where the problem is...
SEPM version: 12.1 RU1
Lan enforcer version: 12.1 RU1
NPS is on a 2008 Standard edition.
PS: i already use the nps for wifi
