/etc/security/audit_user
audit_user is a database that stores per-user auditing preselection data. You can use the audit_user file with other authorization sources, including the NIS map audit_user.byname and the NIS+ table audit_user. Programs use the getauusernam(3BSM) routines to access this information.
The search order for multiple user audit information sources is specified in the /etc/nsswitch.conf file. See nsswitch.conf(4). The lookup follows the search order for passwd(4).
The fields for each user entry are separated by colons (:). Each user is separated from the next by a newline. audit_user does not have general read permission. Each entry in the audit_user file has the form:
username:always-audit-flags:never-audit-flags
The fields are defined as follows:
username
always-audit-flags
never-audit-flags
For a complete description of the audit flags and how to combine them, see audit_control(4).

This functionality is available only if the Basic Security Module (BSM) has been enabled. See bsmconv(1M) for more information.
Configuration changes do not affect audit sessions that are currently running, as the changes do not modify a process's preselection mask. To change the preselection mask on a running process, use the -setpmask option of the auditconfig command (see auditconfig(1M)). If the user logs out and logs back in, the new configuration changes will be reflected in the next audit session.
