Web Authentication and RADIUS

I am trying to get my 5406 web authentication to work with RADIUS and am having no luck. I really don't know what settings I should be using in the Remote Access Policy. What type of authentication should I use?

RADIUS Server
Windows 2003 SP1 Domain Controller
IAS

Switch Config (K 12.14)
aaa authentication web login radius local
aaa authentication web enable radius local
radius-server host 192.168.77.249
radius-server key hp

Thanks

Re: Web Authentication and RADIUS

i should mention that when i hit the web interface it prompts me for a user name and password. if i put in my domain username and password it won't work. if i put in the password for manager i can logon to the web interface.

Re: Web Authentication and RADIUS

Under the Authentication tab of your IAS policy, I think you need to select PAP/SPAP.

Re: Web Authentication and RADIUS

thanks matt. that did it. it's weird because after i initially establish a connection to the switch with my domain credentials I can go back and edit the IAS policy and take off PAP and just enable CHAP v2 and it still works. i confirmed this on a 3500 as well...weird.
