Captive Portal

Is it possible to prevent an other user to log in with the same username when one user is logged in.

I know that you can use -Disable concurrent logins- but then the last user who log in can use the account the user who is already logged in is disconnected.

Thx

In fact yes, it is possible to have the original user stay connected and deny the second user to login.

In order for this to function you need several things:
1) Correct radius server configuration with 'simultaneous-use' set to 1 (
2) don't enable reauthentication
3) leave 'disable concurrent user' disabled
