    [\fB\-r\fR\ <\fIout\ file\fR>] [\fB\-h\fR]
.SH "DESCRIPTION"
.IX Header "DESCRIPTION"
The \fBkadb_check\fR command checks the integrity of the Authentication
Database, reporting any errors or corruption it finds. If there are
problems, do not issue any \fBkas\fR commands until the database is repaired.
.SH "CAUTIONS"
.IX Header "CAUTIONS"
The \fBkadb_check\fR command is only used with the database used by the
obsolete Authentication Server, which should no longer be used. It is
provided for sites that have not yet migrated to a Kerberos version 5
\&\s-1KDC\s0. The Authentication Server and supporting commands, including \fBkdb\fR,
will be removed in a future version of OpenAFS.
.PP
The results can be unpredictable if the Authentication Server makes
changes to the Authentication Database while this command is running. Use
the \fBbos shutdown\fR command to shutdown the local \fBkaserver\fR process
before running this command, or before creating a second copy of the
\&\fIkaserver.DB0\fR file (with a different name) on which to run the command.
.SH "OPTIONS"
.IX Header "OPTIONS"
.IP "\fB\-database\fR <\fIkadb file\fR>" 4
.IX Item "-database <kadb file>"
Names the Authentication Database (copy of the \fIkaserver.DB0\fR file) to
check. If the current working directory is not the location of the file,
provide a pathname, either full or relative to the current working
directory.
.IP "\fB\-uheader\fR" 4
.IX Item "-uheader"
Displays information which Ubik maintains in the database's header.
.IP "\fB\-kheader\fR" 4
.IX Item "-kheader"
Displays information which the Authentication Server maintains in the
database's header.
.IP "\fB\-entries\fR" 4
.IX Item "-entries"
Outputs every entry in the database, providing information similar to that
returned by the \fBkas examine\fR command.
.IP "\fB\-verbose\fR" 4
.IX Item "-verbose"
Reports additional information about the database, including the number of
free (allocated but unused) entries in the database.
.IP "\fB\-rebuild\fR <\fIout file\fR>" 4
.IX Item "-rebuild <out file>"
Names the file in which to record a list of \fBkas\fR commands which, if
issued in the command shell, recreate the current state of the database
being verified. Partial pathnames are interpreted relative to the current
working directory.
.IP "\fB\-help\fR" 4
.IX Item "-help"
Prints the online help for this command. All other valid options are
ignored.
.SH "OUTPUT"
.IX Header "OUTPUT"
If there are errors in the database, the output always reports them on the
standard error stream. If any options other than \fB\-database\fR or \fB\-help\fR
are provided, the output written to the standard output stream includes
additional information as described for each option in \*(L"\s-1OPTIONS\s0\*(R".  The
output is intended for debugging purposes and is meaningful to someone
familiar with the internal structure of the Authentication Database.
.SH "PRIVILEGE REQUIRED"
.IX Header "PRIVILEGE REQUIRED"
The issuer must be logged in as the local superuser \f(CW\*(C`root\*(C'\fR.
