Global Protect User Login

[rcraxton]

Hello,

Is there a way to control the Global Protect login?   I want to have when a user disconnects from GP, the next time user logs in they get prompted for MFA.   As of now, seems user can disconnect/reconnect repeatedly thru out the day and never get prompted with MFA.   How/where do I fix this?

Thanks

Hi @rcraxton ,

Your issue is typically an authentication cookie configuration.  The solution can be different for different vendors.  What MFA product are you using?

Thanks,

Hello Tom,

Not sure how a cookie come into play, but if you have information?   We use DUO.

The Portal and Gateway config each has an option to generate and/or accept an authentication cookie. The configuration is on both the portal and gateway under authentication override. Its having and passing the token for authentication. You can encrypt the cookie with a certificate. 

The cookies are named PanPUAC_*.dat and located in C:\Users\%USERNAME%\AppData\Local\Palo Alto Networks\GlobalProtect

Everything I read appears to put a time limit on the user - then when this limit is reached, user gets kicked out <--- Not what I want.

Looking for way to allow user to login and work, but if they happen to disconnect Global Protect, shut down or reboot machine on next GP connection to our network are prompted by DUO MFA to allow login.   Currently, users have roughly a day of not getting prompted by DUO for MFA.

Thanks

Yes, there are timers associated with the cookie validity. So that would be expected behavior with cookies enabled.

So how do I get to where I want to be?

Disable Authentication Override by removing the generating and accepting of cookie auth under Portal and Gateway.

So by disabling the Authentication Override, this will give what I'm looking for?

Yes, the described behavior would be inline with have Cookie Auth enabled to generate and accept on both Portal and Gateway. Removing those configurations should require users to enter their creds to reconnect.

Hi @rcraxton and @J8Lake ,

If you disable authentication cookies, your users will have to MFA twice - one for the portal and one for the gateway.  That may be acceptable, but if you only want them to MFA once, then you can enable authentication cookies.

You can set the cookie lifetime to a short interval, like a couple minutes.  And after the interval expires, the user will NOT be logged out. The cookie is local like a browser cookie that bypasses the need for MFA.  It only is used when the user logs out and back in.

Thanks,

Tom
