Azure SAML Authentication with multiple PAs

L4 Transporter

Hey,

 

We have a GP configuration with 8 GP Gateways and 2 of them are acting as a GP Portal for backup.

We are using SAML authentication with Azure and wanted to know how to you deploy GP with SAML authentication in large scale.

Currently I have configured 3 SAML apps on Azure one for each PA device but I think it is not the right configuration since now I am getting that each SAML App's domain need to be unique and the Portal domain is for example: vpn.company.com and I need to deploy it to 2 SAML Apps.

My assumptions are that because we only use SP Initiated SAML authentication meaning that the authentication process starts at the PA device I can just add all of the domains that are relevant on a single SAML App and install that Metadata file on all of the Pas. Am I right ?

I just have installed 2 standalone Palo Alto's with SAML. With only 1 Enterprise App in Azure.

So i don't think you need more apps.

Why would you need 2 Apps ?

probably my missunderstanding.

so you have put both of the PA's URLs on the SAML App on Azure ? 

and import the metadata to both of the PAs ? 

thanks

Hi, 

 

Yes i've add both PA URL's in Azure in the same app, see below.

In our case we use an Azure Loadbalancer for the balanced portal configuration.

That portal points to the direct addresses of the firewall for the gateway connectivity.

The whole point of SSO/SAML is to use a single identity provider/authentication provider (Azure AD in this case) and have multiple serviceproviders (GP Portal and Gateways in this case) use it.

 

Did you manage to get it working ?

with single enterprise agent deployed you should be fine.

You just need to add multiple Identifier ( each fw for example ) and reply URL 

It is working.

Hi, is this working? I'm trying to implement the same 

I have added different identifier and still not working,

yes it is working as i described, 1 enterprise SAML application with all the domains that your PA are using by the way if you have a lot i thing your can use *.my.domain for example (although i don't think it is best practice)

if you have problems you can try the "miniOrange SAML Tracer" extention maybe you will see the SAML Assertions

Thank you for the reply,  I use the Globalprotect portal in Azure, like this, "vpn-xxx.domain.com" and it's working fine.  For gateway , its running in on-prem firewall "vpn-yyy.domain.com" ,  I have added  vpn-yyy.domain.com in the "vpn-xxx.domain.com" ( same Azure Enterprise app) and imported metadata. Still not working. I'll try the fresh installation.
