Can't authenticate Mac VPN client from RADIUS server

Hello,

I'm a real noob here so please bear with me.

I have been able to configure my PIX 515E to allow VPN connections onto my network, but what I need to do is set up some sort of user authentication to control access at a user level. From what I've read here and in the Configuration Guide I should be able to do this authentication with a RADIUS server. I'm running a Corriente Networks Elektron Security server which has RADIUS server capabilities. It is running on my (inside) interface at IP 192.168.10.26.

I thought that I had everything configured properly but it never seems to authenticate. I connect, the XAUTH window pops up, I add my username and password as it's configured on my RADIUS server, but when I click OK it just cycles the progress bar at the bottom and eventually times out. The client log doesn't show me anything and the log on the RADIUS server shows me nothing. Any ideas? this seems like it should be simple because I can connect until I attempt to authenticate to the RADIUS server.

TIA for any direction you can provide me.

Christine

Re: Can't authenticate Mac VPN client from RADIUS server

What does this do?

access-group 100 in interface outside

Re: Can't authenticate Mac VPN client from RADIUS server

"access-group 100 in interface outside"

No luck with that.

Thanks though.
