Dynamic tags: Dynamic User Groups can use dynamic tags as match conditions. These tags are assigned based on specific conditions, such as security events or alerts, and can dynamically adjust group membership based on user activity. This is a powerful feature for automatically updating the group based on criteria like suspicious behavior or security incidents.
LDAP attributes: Dynamic User Groups can also use LDAP attributes for membership criteria.
These attributes come from the user's directory information and can be used to group users based on properties such as user roles, departments, or security levels, providing flexibility in defining group membership.

To address the intermittent connectivity issues caused by UDP packet loss, enforcing an SSL tunnel over TCP ensures a reliable connection by using the more robust TCP protocol. In GlobalProtect, this can be achieved by creating a new agent configuration specific to the user, where SSL tunnelling over TCP is enabled. This allows the administrator to isolate the change for troubleshooting purposes without affecting other users.

When administrative functions (licensing, updates) use a data plane interface, the firewall requires outbound connectivity to Palo Alto Networks servers (e.g., updates.paloaltonetworks.com) via that interface. If HTTPS/SSH work but licensing/updates fail, the issue is likely upstream blocking or misrouting. Validating upstream devices (Option B) ensures ports (e.g., 443) and destinations are accessible, resolving the issue.
