       default - system default database file for a trusted system

       The  system  default  database is unique in that it defines system-wide
       global parameters for a trusted system.	It is designed to provide val‐
       ues  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 pro‐
       tected 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  pro‐
       vided.	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 pass‐
       word, terminal control, and device assignment databases, see the corre‐
       sponding	 manual	 pages	listed in the 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.

       This name is set to the string "default".

       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 sys‐
				     tem boot.

       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  correspond  to  pro‐
       tected password fields.	Similarly, fields starting with the 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 section for these databases for a complete descrip‐
       tion of the applicable fields.
