[ATP/FLEX] How to limit ad users in the security policy rule?

Currently, nebula supports "External User Group" (not Specific User) in the security policy rule.
On nebula, go to Firewall > Configure > Firewall settings > Authentication Server > My AD Server and configure AD information.

You also need to add an external user group in Firewall > Configure > Firewall settings > External User Group.

After external user group is configured, you can select it in security policy rule.
