Web Authentication with RSA SecureID on a Cisco Switch

Question

Hi,
I've recently been looking into linking in our Cisco 2960S Gb Switch with RSA SecureID via Radius
I've already managed to link it in for ssh access
but I've not managed to get it working for http / web access to the switch
I think this is because we're using "single use" tokens for maximum security with RSA SecureID
and the web interface attempts to authenticate multiple times against the Radius part of the RSA SecureID server
(okay on the first authentication, but each time after it's going to want a different token code)
I was wondering if anyone knew a way around this? (if there's a way to get the switch to just authenticate once instead of multiple times against the radius server)
For info the switch is a WS-C2960S-24TS-L with IOS 15.0(1)SE2

Hello Chris,
Can you test the following configuration?
aaa group server radius webtac_grp
server
cache expiry 1
cache authorization profile httpauth
cache authentication profile httpauth
aaa authentication login httpauth cache webtac_grp group webtac_grp
aaa authorization exec httpauth cache webtac_grp group webtac_grp
aaa authorization network httpauth cache webtac_grp group webtac_grp
aaa cache profile httpauth
all
ip http server
ip http authentication aaa login-authentication httpauth
ip http authentication aaa exec-authorization httpauth
radius-server host key ******
I know for sure the above configuration works when using TACACS+ instead of RADIUS in order to avoid the multiple prompts due to the JAVA Applets authentication when accessing the IOS GUI. I have not tested it against RSA acting as backend Authentication server.
NOTE: As "aaa authorization exec" is configured the RSA should be sending Attribute Service-Type with value Administrative for it to work as expected.
If this was helpful please rate.
Regards.
