Netflow Generation Appliance (NGA-3240) and authentication with ACS

[REUBEN CHIN]

I would like to configure this appliance to use ACS authentication.  Right now I use local authentication, but would prefer ACS instead. 

Both the WebUI and the console are using this local method and I would much prefer it to use ACS instead.

I get the following prompts:

root@HOSTNAME.localdomain# ip http tacacs+ enable <ACS IP ADDRESS> en-secret-key <KEY>

Failed to enable Tacacs+

Update...

     root@HOSTNAME.localdomain# ip http tacacs+ enable

     Secret key:

     Repeat secret key:

     Successfully enabled Tacacs+

The problem, I'm faced with now is that after entering the above the WebUI is still not accessible.
