       and fixes problems.

       If  no options and no arguments are specified, reports all data corrup‐
       tion problems in all files in

		   allowed only for a local user and the user is not in

	      Normally when the user database is disabled (see
		   userdb(4)),	immediately exits without verifying or repair‐
		   ing the database.  The option overrides this and forces  to
		   verify or repair the database.

	      Verify user names.
		   User	 names	found  in the database are reported if they do
		   not exist in any of the repositories defined in This option
		   could take a long time on a system with many users.

		   not repaired.
