using Azure MFA with Global Protect

Dylanroehrig — Wed, 24 Oct 2018 17:50:36 GMT

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.

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?

I have Azure setup on both the gateway and the portal. No cookies are being generated or used for this. I am having the same thing happen in my environment. Were you able to determine the cause for this on your side?

@minow
I believe that I have found a solution to the Azure not wanted to re-auth users. Within Azure, we had to create conditional access that has session access control. In this section of the conditional access, we selected Sign-in frequency and set this to 1 hour. (Lowest amount of time we could select). Now it seems to be requiring our users to re-auth every hour if they have disconnected. It is my understanding that this won't cause re-auths to users who are still connected, just users who disconnect and then reconnect.

Hope this helps. We have cert authentication as well as Azure with Duo MFA.

Thanks for sharing the info.

Are you using global protect always on method?

Re: using Azure MFA with Global Protect

goepfrichb — Thu, 17 Dec 2020 19:41:11 GMT

We initially were not using the always on. We were just using the on demand.

I have recently setup and tested the Always on. It works like a charm. Is there something that you are having issues with in particular?

Sorry I missed this comment over the summer.

@goepfrichb

I found another way to do it..... under: Device --> Authentication profile --> enter azure profile --> under Authentication tab --> check the option "Enable Single Logout"

this will do the work for logout global protect and azure at the same time

Good to know. Thanks for posting that information.

Hi,

I am trying to get this conditional policy setup to work with the Palo Alto GlobalProtect enterprise app. For some reason O365 is not letting me create it - it hangs. Would you mind sharing your settings with us?

Thanks

Hi, thanks for your share, but after testing this i have a question :

- When the user disconnect globalprotect and reconnect it's ok. Connection with MFA is re ask..

- When the shutdown the pc without disconnect globalprotect, after the reboot it can connection globalprotect automatically.. (No password ot MFA is asking..)

Do you have the same thing ? Have find a solution ?

Thanks,

Re: using Azure MFA with Global Protect

goepfrichb — Mon, 28 Mar 2022 11:36:13 GMT

Yes, I have the same thing. The best that I have found is setting 60 minutes to re-require an authentication. After 60 minutes of their initial authorization, it will require a password and MFA again.

To do that tou have configure a conditional access rule in Azure ?

I've done a condictionnal rule and it's works !!

Too bad I would have preferred a disconnection to closing the post and sending a logout request.

Re: using Azure MFA with Global Protect

goepfrichb — Mon, 28 Mar 2022 14:18:51 GMT

Yes conditional access is what I did. If you find a way to require password and MFA upon disconnect, please let me know. I haven't been able to find anyway to do that yet.
