Radius Error Message Access-Reject, len 20

[callahancalvert]

Hi,

I've been trying to authenticate a user login through utilizing a Virtual server running radius and i keep getting stuck with the error message Access-reject, len 20 any ideas on what could be causing this i have provided screen captures of both my radius server and router debug.

Thanks,

Callahan Calvert

Hello,

you are sending server attribute 6 (service type), can you turn that off ?

Hi,

The error says "Unsupported Attribute". 

It further says "radius-server attribute 6 on-for-login-auth is off". 

If this command is configured and the Service-Type attribute is absent in the Access-Accept message packets, the authentication or authorization fails.

I would suggest that you run a debug aaa authentication and authorization to find out the real cause. It's likely aaa authorization misconfiguration or authorization method missing in the VTY line.
