Palo Alto Networks Exam SSE-Engineer Topic 2 Question 2 Discussion

User mapping learned from sources other than gateway authentication can cause intermittent access issues if it conflicts with the expected user identity used in HIP-based policies. If the firewall is associating the user with an outdated or incorrect mapping, traffic may not match the intended security policies, leading to denials by the Catch-All Deny rule.

If the firewall loses user mapping due to missed HIP report checks, the user may temporarily lose access to policies that require a valid Host Information Profile (HIP) match. When the VPN connection is refreshed, the HIP check is re-initiated, restoring access until the issue repeats.
