au_user_mask(3bsm) [sunos man page]

au_user_mask(3BSM)														au_user_mask(3BSM)

NAME

       au_user_mask - get user's binary preselection mask

SYNOPSIS

       cc [ flag... ] file... -lbsm -lsocket -lnsl  [ library... ]
       #include <bsm/libbsm.h>

       int au_user_mask(char *username, au_mask_t *mask_p);

       The  au_user_mask()  function  reads  the  default, system wide audit classes from  audit_control(4), combines them with the per-user audit
       classes from the audit_user(4) database, and updates the binary preselection mask pointed to by mask_p with the combined value.

       The audit flags in the flags field of the audit_control(4) database and the always-audit-flags and never-audit-flags from the audit_user(4)
       database represent binary audit classes. These fields are combined by au_preselect(3BSM) as follows:

	      mask = ( flags +	always-audit-flags) -  never-audit-flags

       The au_user_mask() function fails only if both the both the audit_control(4) and the audit_user(4) database entries could not be retrieved.
       This allows for flexible configurations.

       Upon successful completion, au_user_mask() returns 0. It fails and returns -1 if both the  audit_control(4) and the  audit_user(4) database
       entries could not be retrieved.

       /etc/security/audit_control     file containing default parameters read by the audit daemon, auditd(1M)

       /etc/security/audit_user        file that stores per-user audit event mask

       The au_user_mask() function should be called by programs like login(1) which set a process's preselection  mask	with  setaudit(2).  getau-
       dit(2) should be used to obtain audit characteristics for the current process.

       The functionality described on this manual page is available only if the Basic Security Module (BSM) has been enabled.  See bsmconv(1M) for
       more information.

NAME

       audit_user - per-user auditing data file

SYNOPSIS

       /etc/security/audit_user

DESCRIPTION

       audit_user  is  an  access-restricted  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 	       User's login name.

       always-audit-flags      Flags specifying event classes to always audit.

       never-audit-flags       Flags specifying event classes to never audit.

       For a complete description of the audit flags and how to combine them, see audit_control(4).
