NAME

       authck - Checks internal consistency of the authentication databases (Enhanced Security)

SYNOPSIS

       /tcb/bin/authck [ options ]

FLAGS

       NOTE:  At least one of the -a, -p, -t, or -f flags is required.	Turns on the -p, -t, and -f flags collectively.
       Examines  the  file control database for syntax and value specification errors. Each entry is examined to verify that the syntax is correct
       and that values such as user names, group names, modes, object types, and other security attributes, depending on the system configuration,
       are  valid.  Checks  are  also made to ensure that continuation lines are handled properly in ASCII files and that each entry is terminated
       with the chkent field. Errors detected in the file control database cannot be corrected by authck since in most cases the command is unable
       to  determine  what the entry should contain. Instead, errors are detected and correction of these errors is left to the system administra-
       tor.  Checks the protected password database (user profiles).  The cross-references between the protected password database and /etc/passwd
       are checked to make sure that they are mutually consistent.  Then fields in the protected password database are checked for reasonable val-
       ues.  For instance, all timestamps of past events are checked to make sure that they have times less than the  times  returned  by  time().
       Checks the fields in the terminal control database for reasonable values.  All timestamps of past events are checked to make sure they have
       times less than those returned by time().  Provides running diagnostics as the program proceeds.  It also produces warnings on unusual con-
       ditions that may not cause program errors.

DESCRIPTION

       The  authck  program checks both the overall structure and internal field consistency of all components of the authentication databases. It
       reports all problems it finds.  To invoke this program you must log in as root.

EXIT VALUES

       If authck did not detect any inconsistencies, it exits with a status of 0 (zero).  If the user is not authorized, authck exits with a  sta-
       tus  of 1.  If the user specifies the wrong argument syntax, authck exits with a status of 2.  Otherwise, authck exits with status equal to
       the number of inconsistencies found.

FILES

       Specifies the command path.  System password file.  Protected password database.  File control database.  Terminal control database.
       System defaults database.
