Captive Portal authentication by Radius/AD only one time per session

[marcoafm]

I have Captive Portal authentication by Radius/AD working perfectly but I can't allow the users to get internet access in its private devices (smartphones, tablets, etc) and how it is people are able to connect to the internet thru Captive Portal X times.

I need some tip about how to limit a Captive Portal authentication by Radius/AD.

I need that each AD user is able to log in only one time per session.

In this way, a person will authenticate yourself using the AD user/pass in his/her laptop for work and if they try to connect a tablet, as soon as the AD user/pass is entered again a error must be returned and the access not allowed.

Any suggestions?

Thanks in advance.

In your Captive Portal configuration, you 'll find Concurrent user logins = If enabled only the most recent login per username will be active. Subsequent logins will cause machines previously logged in with the same username to be disconnected.
