Configure User-ID in Prisma Access

Configure Your Prisma Access Deployment to Retrieve Group Mapping

Configure User-ID for Remote Network Deployments

The process for retrieving User-ID information for Prisma Access is similar to configuring User-ID for on-premise Palo Alto Networks next-generation firewalls. To configure User ID-to-IP address mapping for Prisma Access, use the following workflow.

Map IP addresses to users in Prisma Access.
- To use a Windows-based User-ID Agent for IP address-to-username mapping, create a dedicated service account for the User-ID agent, then configure user mapping using the Windows User-ID agent.
- To use the PAN-OS integrated User-ID Agent for IP address-to-username mapping, Create a dedicated service account for the User-ID Agent, then configure User-ID using the PAN-OS integrated User-ID agent.
  If you use either a Windows or PAN-OS User-ID Agent, use the User-ID Agent Address (PanoramaCloud ServicesStatusNetwork DetailsService Connection) from Prisma Access in your User-ID agent configuration to configure your on-premise firewalls to retrieve User-ID mappings from the Prisma Access infrastructure. For more information about User-ID redistribution from Prisma Access to an on-premises firewall, see Redistribute User-ID Information From Prisma Access to an On-Premise Firewall.
  
  By default, the User-ID agent uses port 5007 to listen for User-ID information requests. Make sure that you implement security policies that allow User-ID traffic from this port between Prisma Access and the Active Directory server or User-ID Agent.
  
  You can also use the paloalto-userid-agent App ID to retrieve the information from the Windows domain controller; however, if you do this, you must decrypt the SSL traffic for User-ID.
- To enable IP address-to-username mapping for users with client systems that aren’t logged in to your domain servers—for example, users running Linux clients that don’t log in to the domain—you can Map IP Addresses to Usernames Using Authentication Portal (formerly Captive Portal).
  To authenticate users using MFA, SAML, or Authentication Portal, we recommend mapping a hostname to the Captive Portal Redirect IP Address in Prisma Access and associating it with your internal DNS servers. If you choose to use Kerberos single sign-on (SSO) with the authentication portal, the hostname is required. Alternatively, you can use the Captive Portal Redirect IP Address by itself to redirect users.
  To find the Captive Portal Redirect IP Address, select PanoramaCloud ServicesStatusNetwork DetailsService Infrastructure. Prisma Access assigns this IP address from the infrastructure subnet IP address pool.
- To enable IP address-to-username mapping using syslog listening, Configure User-ID to Monitor Syslog Senders for User Mapping.
- To enable IP address-to-username mapping for users on Windows-based terminal servers, Configure User Mapping for Terminal Server Users.
- To enable IP address-to-username mapping using an XML API, Send User Mappings to User-ID Using the XML API.
- To enable IP address-to-username mapping without using an agent, Configure User-ID for Prisma Access Using the PAN-OS Integrated User-ID Agent.
Allow Panorama to use group mappings in security policies.
- To allow Panorama to retrieve group mapping information, add one or more next-generation firewalls to your deployment and then configure the firewall as a Master Device.
  We recommend using a Master Device in Prisma Access User-ID deployments, because it allows you to select groups from drop-down lists in policies that you create and configure in Panorama, which simplifies group-based policy configuration.
- If you don’t use a master device, you can configure group-based policy by specifying the full distinguished name (DN) of the group.

Configure User-ID for Prisma Access Using the PAN-OS Integrated User-ID Agent

The following procedure shows how to configure the PAN-OS integrated User-ID agent on the firewall for IP address-to-username mapping. The integrated User-ID agent performs the same tasks as the Windows-based agent with the exception of NetBIOS client probing. While we support WMI probing, we do not recommend it.

Create the User-ID service account in the Windows Active Directory (AD) server that is being used by the authentication server.
Be sure that the user you create is part of the following groups:
- Distributed COM Users
- Event Log Readers
- Server Operators
We recommend only making these group associations. You do not have to configure Domain Admin or Enterprise Admin privileges for the User-ID service account to work correctly. Giving privileges to the account that aren’t required can give your network a larger attack surface.
Configure Windows Management Instrumentation (WMI) on the AD server.
The device uses WMI Authentication and you must modify the CIMV2 security properties on the AD server that connects to the device.
1. Open a command prompt window and run the wmimgmt.msc command.
2. In the WMI Control pane, right-click WMI Control, choose Properties, and select the Security tab.
Make the following changes in the CIMV2 folder:
1. Select the CIMV2 folder.
2. Click Security.
3. Click Add
4. Select the service account you created in Step 1.
  This example uses the UserID user with the email of userid@example.com.
5. Check Allow for the Enable Account and Remote Enable for the account you created.
6. Click Apply.
7. Click OK.
In Panorama, select DeviceUser IdentificationUser Mapping and click the gear icon to edit the settings.
Be sure that you have selected the Remote_Network_Template at the top of the page.
Configure the Windows Remote Management (WinRM) protocol to monitor your Active Directory server.
See the WinRM documentation in the PAN-OS Administrator’s Guide for details.
