Working on an idea to allow a manner of login/logout for users coming through captive portal auth.
On a system that may or may not be identified on the back-end, I can load the captive portal page URL manually and set/change the user-id.
When I try to load the page again, I only get a blank page - is there a URL I can load to generate a 'logout' or ID clear event, or at least some way to force the captive portal to load again so users can enter a dummy 'logout' user?
By design Captive-Portal will only redirect to the login page if the user is considered "unknown" by the firewall. The only way I can think of to force the user to login again manually is by running:
> clear user-cache ip x.x.x.x
Of course this isn't ideal, because you'll have to manually clear the user-ip-mapping for each user manually from the cli.
The only other thing I can think of that may help is if you lowered the expiration timer for the Captive-Portal mappings.
Thanks for the info. We are looking into generating a user-id event against AD as workaround for this. This is for iPads primarily we are thinking a custom app that generates an LDAP login - "logout" would be changing the user-id to a user with no rights.
Hi...You may want to review this method: https://live.paloaltonetworks.com/docs/DOC-1642.
Also, if your iPad users are logging into Exchange to get email, our 4.1 UserID agent will monitor Exchange events now. Thanks.
