IOS authentication with MS IAS (AAA/radius)

John Smith
Posts: n/a
here is my config so far:
aaa new-model
aaa authentication login default group radius local
aaa authentication enable default group radius
radius-server host auth-port 1645 acct-port 1646 key 7 ******

IOS (tm) 3600 Software (C3620-I-M), Version 12.2(29), RELEASE SOFTWARE

i am able to telnet to the router ok, and authenticate via radius using my
windows domain information, but when i attempt to 'enable', i get an
error. on the IAS server, in the logs, it says $enab15$ was denied access...
I understand this, but what i dont understand is why isn't it using my
windows username when i attempt to 'enable'. or is there a way to force it

any hints/help?

User Access Verification

Username: username
Password: *******

% Error in authentication.

Hi John,

The username is fixed which is $enable15$ for enable authentication.

Here is the best tutorial I have found for Cisco Radius authentication using Microsoft IAS. The video tutorials make this process very simple.
