ACS 5.0 and RADIUS attribute Class

Unanswered Question

We have a setup with ASA and ACS 5.0 and are trying to send Radius attribute Class (25) back from the ACS to the ASA to assign Group-policy.

The problem we have is that the ACS responds with somekind of session-id in as value for the class-attribute (for example "SERVERXX/12345678/08") instead of the value we have configured (for example "OU=GRP1").

Have we configured something wrong?

This is an evaluation-version of ACS.

Best regards,

Before you can enable attributes on a per-user basis, you must enable the Per-user TACACS+/RADIUS Attributes option on the Advanced Options page in the Interface Configuration section. After enabling per-user attributes, a user column will appear as disabled in the Interface Configuration page for that attribute.

I cannot find this option in ACS 5.0.

I do receive per-user attibutes, the only thing is that the class-attribute contains the wrong information (i.e. not the information i typed in).

Did you find a way to send the good class-attribute as I'm experiencing the same problem with ACS5.

No, we have not found a solution yet.

We might use another software instead.
