I have a group setup in Cisco ACS (V4.2) which holds dynamic users that have successfully authenticated through wireless. No problem. The users in this group have authenticated from a guest wireless setup. I want to prevent the same user from logging in multiple times.
For example, the project users credentials suppplied bya library ticket which is usique to that user, I want to prevent that user from giving their details to someone next to them and getting them to use their laptop. Preventing multiple logins would prevent this.
Can I do this in ACS anywhere??
