 NAME
      devassign - device assignment database file for a trusted system

 SYNOPSIS
      /tcb/files/devassign

 DESCRIPTION
      The system supports a single device assignment database that contains
      entries for local login terminals.

      The format of the terminal control database file is identical to other
      trusted system authentication database files. For more information on
      the file format, see authcap(4).	The file consists of keyword field
      identifiers and values for those fields. The keyword identifiers
      supported and their use include:

      v_devs	     This field specifies a comma separated list of aliases
		     that refer to the same device defined by the entry. Use
		     of this field avoids the need to replicate device
		     assignment database entries for all device aliases.

      v_type	     This field specifies the device that is described by
		     the entry.	 Device types supported include:

			  terminal	 The device is assigned as a local
					 login terminal device.

      v_users	     This field, if specified, contains a comma separated
		     list of user names that are permitted to use the device
		     for login or the import/export of data.  If the list is
		     not present, all users are permitted to use the device.
		     If the list is present, it is searched for a match by
		     the login program to determine if the user is permitted
		     to use the device.

 EXAMPLES
      The following is an example of a device assignment database entry for
      a terminal device assigned as a login device:

	   tty0:v_devs=/dev/tty0:\
		:v_type=terminal:\
		:chkent:

 WARNINGS
      Remote terminals (ptys) should not be added to the devassign or ttys
      databases.  Device name formats treated as ptys by login are:

	   ptym/*
	   pts/*
	   pty/*
