When a non-global zone is installed, the audit_control file and the audit_user file in the global zone are copied to the zone's /etc/security directory. These files might require modification to reflect the zone's audit needs.
For example, each zone can be configured to audit some users differently from others. To apply different per-user preselection criteria, both the audit_control and the audit_user files must be edited. The audit_user file in the non-global zone might also require revisions to reflect the user base for the zone if necessary. Because each zone can be configured differently with regard to auditing users, it is possible for the audit_user file to be empty.
