Preventing Multiple Logins from the same usernames

[briant]

We are trying to prevent people from logging into our dial in servers multiple times with just one account.

Haven't had any luck finding references on this.

I assume that you have Cisco Secure ACS as a AAA server. So under the user setup, you can configure "max-session" to 1 to limit the max session login from that user to 1. Also you can configure the same under group settings too.

Here is the link for that
