RADIUS authentication

We have a 3640 accepting analogue and isdn calls and authenticating users using radius via a IAS service running on win2k server. All is working well apart from isdn which looks like it's passed authentication ("Pass" on debug radius) but the user gets disconnected. The debug radius is complaining of "unrecognized Vendor code 311" after the aaa/authen status - pass.

In the IAS logs, i see two unknown attribute/value pairs:

4294967209,120,

4294967210,50,

Has anyone seen this before and is there a solution.

Re: RADIUS authentication

We need to see the debug for

debug aaa authorization

debug aaa per

debug radius

Based on that we can decode the authorization attributes passed to 3640 with "access accept" reply.

By the way, do you see any special attributes configured for that user in IAS?

You can just configure IAS with basic authorization attributes required and test it.
