using Azure MFA with Global Protect

Hello,

 

To configure Global Protect to use our already Existing MS MFA server, I followed this KB: https://knowledgebase.paloaltonetworks.com/KCSArticleDetail?id=kA10g000000ClkkCAC 

 

I think I had to do one or two extra things as well, but in any case it's working.  However, it only prompts for the second factor if after I disconnect the Global Protect client, I go to Settings and click Sign Out.  If I don't sign out, when I reconnect, I am not prompted for the second factor.  Is this on some kind of timer or something?  I tried putting the machine to sleep, logging out, and rebooting it but none of those things caused it to prompt. Is there a way to get it to require the second factor every time I reconnect?

@Dylanroehrig,

Sounds like you are using cookie auth somewhere in your GP configuration.

Hmm, where is an example of someplace that might be?  I don't recall setting cookie authentication anyplace.

--> Global Protect Gateway Configuration --> Agent --> Client Settings --> Configs --> Authentication Override --> Accept Cookie for Authentication Override

Sorry, I forgot to come back and mention that i found the cookie settings in the GlobalProtect Portal config. Does it matter if I change it there, on the gateway, or both?

@Dylanroehrig,

If you don't want this behaviour just disable it on both.

@BPry thanks, it seems to work fine by just disabling it on the portal but I'll remove on both to be on the safe side.  Thanks for your help.

Re: using Azure MFA with Global Protect

this is the same behavior that we have and we do not use cookie authentication.

there is some kind of cookie that the GP using with the SAML.. probably Azure is signing the response for some period of time, and as long as the GP client store that signed cookie and if it valid it wont prompt with authentication.....

Need to ask you that on Portal you have Radius authen and on Gateway you have SAML from azure?

Also you have authentication override on both Portal and Gateway?

 

When you refresh or disconnect the client does it ask you for single authentication or both?
