Enabled Captive portal, but after logging out also users where able to access internet

[karthik_sunkoju]

Hi,

Enabled identity awareness in firewall and created users and added them to user group, same has been added into policy with source as user group name and Destination as Any, action as user authentication, 

Main query is when they login through captive portal internet should access and if he log outs then he should not access internet,

can any one suggest me how to do this??

Regards,
