Captive Portal w/2FA in Azure

L2 Linker

Hi All -

Hopefully I make this clear.  

 

What I'm looking to do is set up Captive Portal with a push notification in Azure AD.  I can't seem to find any documentation around this, can someone give me the general steps or point me to existing documentation?

 

Thanks in advance.

@MP18 I found that one, but there are parts that don't make sense to me.

Like

"Next lets create an authentication profile that will be used in our captive portal, navigate to Objects > Authentication and press “Add”:"

Set the following values and press ok:

Name: Anything you like!
Authentication Method: Browser-challenge (doesn’t really matter here as the request will be redirected to Azure-AD anyway)
Authentication Profile: The Azure-AD authenticaiton profile we setup in the previous section
Message: Leave default- users will not see this anyway.

 

But then I don't see how that ties into anything???

@MP18 It also says:

n our case we want to that to a FQDN that users using an internal DNS server will point to an internal interface on the firewall. For example https://internal.azureadmin.co.uk:6082/SAML20/SP which would resolve to an internal interface on the firewall (such as 192.168.100.1). The port number here is the port the Palo Alto hosts its captive portal service when enabled.

Reply URL (Assertion Consumer Service URL):
This is the URL that Azure will send the user back to after the SAML authentication processs completes, in our case we can use the same URL as the Identifier- for example- https://internal.azureadmin.co.uk:6082/SAML20/SP

 

Use the same reply URL? That doesn't seem right?

Hello,

One thing to remember with Captive portal is that its used only for matching a user to and IP address for mapping. If a use is already known, the portal will not be presented to the user.

Hope that makes sense.

For CP you export the cert from the Azure to PA.

Yes URL for Identity Provider SSO URL it is same as in Azure.

@MP18 @OtakarKlier 

Here is what I'm hoping will happen.  User crosses from zone to another and is presented with the CP.  User puts in username and password and then gets a push notification to there phone via Microsoft Authenticator.  User clicks "approve" and the CP process completes.  All internal.

 

Currently, I have CP set up so that User crosses from zone to another and is presented with the CP. User puts in username and password and the CP process completes.

 

Is what I'm hoping for possible?  Am I explaining it correctly?

@RobertShawver 

Yes you are sharing correctly.

Now the question is how

@RobertShawver 

 

If you have not done any CP config then you can also check with your SE How to do it?

Are you the one who will do configuration in Azure?
