RE: OT-Radius authentication from a Juniper client to a Cisco

You are right James

our Radius server is not responding at all rekonizing Authenticate-Only Service-Type incoming packets.

Now we got two way to solve problem:

a) change Juniper configuration (best way, but router is managed by another staff don't seem very happy to do this ...)
b) change Cisco Secure Radius way to manage Authenticate-Only incoming packet (do anybody know how to get that? may be touching something tricky in Cisco Radius conf?)

Thank you very much

Stefano

Is your RADIUS server responding but omiting the Juniper VSA by chance ?
Juniper, along with some other vendors has a habit of setting Service-Type
to "Authenticate-Only" in the request packet...per RFC, if the RADIUS server
sees "Authenticate-Only" it is not required to return any authorization
data. One fix is to manipulate the request packet on input if ACS lets you
do that and change the Service-Type to "Login".

Hi

I got troubles interfacing a Juniper router to a Cisco Secure ACS Radius
server.

Juniper staff seems sending correctelly authen packet to Cisco Radius,
Radius server reports correct authentication, but I can't see answer
ackwoledgment to Juniper that goes to retry, after 3 attempt I got time out
(of course!) on dialup PC.

Inside Cisco Secure "Network Configuration" I can choose between Radius IETF
or Radius Juniper, but with both confs Radius seems don't working.

Anybody has got experience with Cisco Radius and Juniper?

Ciao
