Symptom


  • User is not hitting the correct user-based Security Policy when using GlobalProtect.
  • When GP is used by the user, we can see that the Firewall learns the user-ip-mapping (same IP) from both the GP and UIA:
> show user ip-user-mapping-mp all | match <username>

10.10.10.x vsys1 (User-ID Hub) UIA domain\<username> 2659 10.10.10.x vsys3 GP otherdomain\<username> 10799
 


Environment


  • GlobalProtect (GP) Gateway
  • User-ID Agent (UIA)
  • Supported PAN-OS


Cause


  • The firewall always uses the latest (most recent) IP-to-user mapping it receives when multiple sources provide the same information.
  • This mapping is used until its expiration time. 
> show user ip-user-mapping ip 10.10.10.x
IP address: 10.10.10.x (vsys1(User-ID Hub)) User: domain\<username> From: UIA Idle Timeout: 2582s Max. TTL: 2582s HIP Query: Disabled Group(s): domain\<username>(85929)


Resolution


  1. Exclude the GlobalProtect Client IP Pools from the User-ID Agent.
  2. Refer to the steps in the knowledge article GlobalProtect users losing network access some minutes after being connected.
