NAME

       User::Identity::System - physical system of a person

INHERITANCE

	User::Identity::System
	  is a User::Identity::Item

SYNOPSIS

	use User::Identity;
	use User::Identity::System;
	my $me	 = User::Identity->new(...);
	my $server = User::Identity::System->new(...);
	$me->add(system => $server);

	# Simpler

	use User::Identity;
	my $me	 = User::Identity->new(...);
	my $addr = $me->add(system => ...);

DESCRIPTION

       The "User::Identity::System" object contains the description of the user's presence on a system.  The systems are collected by an
       User::Identity::Collection::Systems object.

       Nearly all methods can return undef.

METHODS

   Constructors
       User::Identity::System->new([NAME], OPTIONS)

	   Create a new system.  You can specify a name as first argument, or in the OPTION list.  Without a specific name, the organization is
	   used as name.

	    Option     --Defined in	--Default
	    description  User::Identity::Item  undef
	    hostname			  'localhost'
	    location			  undef
	    name	 User::Identity::Item  <required>
	    os				  undef
	    parent	 User::Identity::Item  undef
	    password			  undef
	    username			  undef

	   . description => STRING

	   . hostname => DOMAIN

	       The hostname of the described system.  It is prefered to use full system names, not abbreviations.  For instance, you can better
	       use "www.tux.aq" than "www" to avoid confusion.

	   . location => NICKNAME|OBJECT

	       The NICKNAME of a location which is defined for the same user.  You can also specify a User::Identity::Location OBJECT.

	   . name => STRING

	   . os => STRING

	       The name of the operating system which is run on the server.  It is adviced to use the names as used by Perl's $^O variable.  See
	       the perlvar man-page for this variable, and perlport for the possible values.

	   . parent => OBJECT

	   . password => STRING

	       The password to be used to login.  This password must be un-encoded: directly usable.  Be warned that storing un-encoded passwords
	       is a high security list.

	   . username => STRING

	       The username to be used to login to this host.

	   See "Attributes" in User::Identity::Item

       $obj->hostname

       $obj->location

DIAGNOSTICS

       Error: $object is not a collection.

	   The first argument is an object, but not of a class which extends User::Identity::Collection.

       Error: Cannot load collection module for $type ($class).

	   Either the specified $type does not exist, or that module named $class returns compilation errors.  If the type as specified in the
	   warning is not the name of a package, you specified a nickname which was not defined.  Maybe you forgot the 'require' the package which
	   defines the nickname.

       Error: Creation of a collection via $class failed.

	   The $class did compile, but it was not possible to create an object of that class using the options you specified.

       Error: Don't know what type of collection you want to add.

	   If you add a collection, it must either by a collection object or a list of options which can be used to create a collection object.
	   In the latter case, the type of collection must be specified.

       Warning: No collection $name

	   The collection with $name does not exist and can not be created.
