 NAME
      default - system default database file for a trusted system

 SYNOPSIS
      /tcb/files/auth/system/default

 DESCRIPTION
      The system default database is unique in that it defines system-wide
      global parameters for a trusted system.  It is designed to provide
      values for users and devices on a global scale rather than requiring
      an administrator to replicate values in user or device databases when
      they are all the same. In addition to being easier to specify global
      values, it is also much easier to make a global system change if
      necessary.

      The system default database is made up of four types of values:

      system-wide parameters	    These are parameters that do not have
				    corresponding specifications in any
				    other trusted system database.  If a
				    system-wide parameter is not specified
				    in the default database, then it is
				    undefined.

      user parameters		    These parameters are typically specified
				    in a protected password database file.

      terminal control parameters   These parameters are typically specified
				    in the terminal control database file.

      device assignment parameters  These parameters are typically specified
				    in the device assignment database file.

      System default parameters may be specified for fields found in the
      protected password, terminal control, and device assignment databases.
      When a specific entry is retrieved from one of these databases, a
      structure called, ufld that contains all of the explicitly specified
      values, is provided to the caller.  A second structure, called sfld,
      is also provided which defines those values supplied from the system
      default database. Each of these structures has a corresponding flag
      structure called uflg and sflg, respectively, that indicates which
      fields in each structure have been specified and are valid for use.
      Programs honor the user or device specific value first if one is
      provided.	 Otherwise, the program may choose to use the system default
      value if one has been specified. If neither value is specified, the
      program may supply a reasonable default value or abort.

      For descriptions of the specific fields provided by the protected
      password, terminal control, and device assignment databases, see the
      corresponding manual pages listed in the SEE ALSO section for those
      databases. The following fields are unique to the system default

      database and can not be specified in any of the other system
      databases.

      d_name			    This name is set to the string
				    "default".

      d_boot_authenticate	    This flag field indicates whether or not
				    boot authentication is required to boot
				    the machine. If authentication is
				    required, it is performed by the system
				    init(1M) program prior to completing
				    system boot.

 EXAMPLES
      The following is an example of a typical system default database.
      Refer to authcap(4) for descriptions of the file and line formats.

      This system default database defines the four different types of
      values which are supported. First, values that can be assigned on a
      system-wide only basis are defined.  Boot authentication at system
      startup is not enabled.  Login programs will provide password
      expiration warnings if the password expires in less than 604800
      seconds from the current system time (this translates into 60*60*24*7
      or 7 days).

      The system default database also defines numerous protected password
      database default values.	Fields that begin with u_ correspond to
      protected password fields.  Similarly, fields starting with the t_
      prefix are terminal control database fields.  These field types are
      used to supply system-wide default values if a user or device specific
      value is not supplied by the corresponding database. See the
      appropriate manual pages listed in the SEE ALSO section for these
      databases for a complete description of the applicable fields.
