Prisma Access (Managed by Strata Cloud Manager) Prisma Access (Managed by Panorama)	Prisma Access license

If your users access services and applications that are external to your network, you can use SAML to integrate Prisma Access with an identity provider (IdP) that controls access to both external and internal services and applications. SAML single sign-on (SSO) enables one login to access multiple applications and is helpful in environments where each user accesses many applications and authenticating for each one would impede user productivity.

Prisma Access for Users provides enterprise authentication via Security Assertion Markup Language (SAML). You can use SAML 2.0 to authenticate Prisma Access mobile users. The Prisma Access portal and gateways act as SAML Service Provider (SP). When a mobile user attempts to connect, Prisma Access returns an authentication request to the client browser, which in turn sends it to your SAML IdP to authenticate the user. You can use any third-party software that supports SAML 2.0 as SAML identity provider (IdP).

The following workflows use Okta as the SAML IdP.

SAML Authentication Using Okta as IdP for Mobile Users (Strata Cloud Manager)

Configure Prisma Access to establish a trust relationship with your Okta IdP for SAML 2.0 authentication of your mobile users.

Use the following procedure to configure a trust relationship between Prisma Access and your Okta IdP:

Enable Mobile Users to Authenticate to Prisma Access.

Complete the steps for defining the Service Provider (SP) settings, including generating or importing the certificate that Prisma Access uses to sign SAML messages that it sends to the identity provider (IdP).
Export the Prisma Access signing certificate so that you can import it onto your IdP.
Log into Okta as an administrator and create and create SAML 2.0 applications for Prisma Access.
1. Create a new application integration for Prisma Access. Specify the Platform Type as Web and the sign-on method as SAML 2.0 and click Create.
2. Configure the following application integration options:
  Single sign on URL—Enter the URL for the portal (i.e. https://portal114.gpcloudservice.com:443/SAML20/SP/ACS)
  Use this for Recipient URL and Destination URL—Select this check box.
  Allow this app to request other SSO URLs—Select this check box and add the URLs for all Prisma Access gateways on the list you copied in the Requestable SSO URLs field.
  Audience URI (SP Entity ID)—Enter the URL for the portal (i.e. https://portal114.gpcloudservice.com:443/SAML20/SP).
  Default RelayState—Leave blank.
  Name ID format—Select EmailAddress.
  Application username—Select Okta Username.
3. Select Show Advanced Settings and configure these settings:
  Allow application to initiate Single Logout—Select this check box.

  Where <Prisma-Access-FQDN> is the FQDN you defined for Prisma Access when you set up the environment.
  SP Issuer—Enter the issuer for the service provider.
  Signature Certificate—Browse to and then select the SAML signing certificate that you exported from Prisma Access, then click Upload Certificate.
4. In the ATTRIBUTE STATEMENTS (OPTIONAL) area, specify users, Name formats, and values in Okta Expression Language.
  
  These fields reference, transform and combine attributes to define the Username attribute format to match what you set up on Prisma Access. For example, specify a name format of Basic and a Value of user.firstName.
5. Optionally, in the Group Attribute Statements (Optional) area, create group attribute options.
  
  You can’t use group information that’s retrieved from the SAML assertion in either security policy rules or the GlobalProtect app configuration.
6. Save the configuration.
Complete the configuration of the SAML 2.0 web application in Okta and enable the users to use the application. Click View Setup Instructions for details.
To download the metadata files for the portal and gateways, click Identity Provider metadata and copy that information.
Import the metadata file and the CA certificate from Okta into Prisma Access.
1. Log in to the Strata Cloud Manager on the hub and go to WorkflowsPrisma Access SetupMobile Users. Select GlobalProtect Setup or Explicit Proxy Setup and edit the User Authentication configuration.
2. In SAML IdP Profile click Add SAML IdP Profile and Import the metadata file you exported from the Okta server.

SAML Authentication Using Okta as IdP for Mobile Users (Panorama)

There are two different procedures you can take to use SAML authentication with Okta in Prisma Access.

If you are able to access the Palo Alto Networks—Strata Cloud Manager in Okta, use the steps in
Configure SAML Authentication for Prisma Access Using Okta With the Strata Cloud Manager
to configure Okta authentication with Prisma Access. This procedure simplifies the SAML authentication process because you do not have to enter each gateway name manually in Okta.
If you cannot access the Palo Alto Networks—Strata Cloud Manager in Okta, you must configure each gateway manually in Okta. See
Configure SAML Authentication for Prisma Access Using Okta Without the Strata Cloud Manager
for details.

Complete this task to configure SAML 2.0 in Prisma Access by using Okta as the IdP.

Configure SAML Authentication for Prisma Access Using Okta With the Strata Cloud Manager

If you are able to access the Palo Alto Networks—Strata Cloud Manager in Okta, use the steps in this procedure to configure SAML authentication using Prisma Access.

Log in to the Panorama that manages Prisma Access and configure the SAML signing certificate that you want to use with SAML 2.0.
Prisma Access requires a SAML certificate to sign SAML responses and assertions. You can either generate the signing SAML signing certificate used by the portal and gateways, or you can import it. Only a Panorama administrator or Superuser can generate or import this certificate.
- To Generate a Certificate and export it:
  1. Select DeviceMobile_User_TemplateCertificate ManagementCertificatesDevice Certificates.
    You can also create this certificate in another template, but you must include this certificate as part of the Mobile_User_Template_Stack to use it with the Prisma Access portal and gateways.
  2. Click Generate.
  3. Select the certificate, then click Export Certificate.
  4. Export the certificate in PEM format.
    
    Do not select the Export private key check box.
- To Import a Certificate:
  1. Select DeviceMobile_User_TemplateCertificate ManagementCertificatesDevice Certificates.
    Be sure to include this certificate as part of the Mobile_User_Template_Stack.
  2. Click Import and enter a Certificate Name.
  3. Select the Shared check box.
  4. Enter the path and name of the Certificate File received from the CA, or Browse to find the file.
  5. Click OK.
Find the portal and gateway FQDNs to use as your Unique Gateway ID in Okta.

For gateways, you a truncated FQDN that you take from the gateway FQDNs. For portals, you use the entire FQDN. You use the portal and gateway FQDNs when you configure Okta in a later step.
1. Select PanoramaCloud ServicesStatusNetwork Details and click either the Mobile Users or Mobile Users - GlobalProtect radio button, depending on your deployment.
2. In the Portals area, make a note of the full Portal hostname.
3. In the Gateways area, take the gateway name and make a note of the data between the last dash in the gateway name and .gw.gpcloudservice.com.
  For example:
  
  Given a gateway name of india-west-acme.gp123abc.gw.gpcloudservice.com, make a note of the truncated FQDN acme.gp123abc.
  Given a gateway name of uzbekistan-acme.gp123abc.gw.gpcloudservice.com, make a note of the truncated FQDN acme.gp123abc.
  Given a gateway name of us-northwest-g-acme.gp123abc.gw.gpcloudservice.com, make a note of the truncated FQDN acme.gp123abc.
Use the Palo Alto Networks - Strata Cloud Manager to configure SAML login settings.

Strata Cloud Manager is part of the Okta Integration Network (OIN) and simplifies the Prisma Access SAML authentication process.

If you cannot access the Palo Alto Networks - Strata Cloud Manager, you must configure each gateway manually in Okta by completing the procedure in
