Description: ===========================
        Global principal definition
        ===========================
        
        Global principals are defined via ZCML.  There are several kinds of
        principals that can be defined.
        
        Authenticated Users
        -------------------
        
        There are principals that can log in:
        
            >>> zcml("""
            ...    <configure xmlns="http://namespaces.zope.org/zope">
            ...
            ...      <principal
            ...         id="zope.manager"
            ...         title="Manager"
            ...         description="System Manager"
            ...         login="admin"
            ...         password_manager="SHA1"
            ...         password="40bd001563085fc35165329ea1ff5c5ecbdbbeef"
            ...         />
            ...
            ...    </configure>
            ... """)
        
            >>> import pprint
            >>> from zope.principalregistry.principalregistry import principalRegistry
            >>> [p] = principalRegistry.getPrincipals('')
            >>> p.id, p.title, p.description, p.getLogin(), p.validate('123')
            ('zope.manager', u'Manager', u'System Manager', u'admin', True)
        
        The unauthenticated principal
        -----------------------------
        
        There is the unauthenticated principal:
        
            >>> zcml("""
            ...    <configure
            ...        xmlns="http://namespaces.zope.org/zope"
            ...        >
            ...
            ...      <unauthenticatedPrincipal
            ...         id="zope.unknown"
            ...         title="Anonymous user"
            ...         description="A person we don't know"
            ...         />
            ...
            ...    </configure>
            ... """)
        
            >>> p = principalRegistry.unauthenticatedPrincipal()
            >>> p.id, p.title, p.description
            ('zope.unknown', u'Anonymous user', u"A person we don't know")
        
        The unauthenticated principal will also be registered as a utility.
        This is to provide easy access to the data defined for the principal so
        that other (more featureful) principal objects can be created for the
        same principal.
        
            >>> from zope import component
            >>> from zope.authentication import interfaces
            >>> p = component.getUtility(interfaces.IUnauthenticatedPrincipal)
            >>> p.id, p.title, p.description
            ('zope.unknown', u'Anonymous user', u"A person we don't know")
        
        The unauthenticated group
        -------------------------
        
        An unauthenticated group can also be defined in ZCML:
        
            >>> zcml("""
            ...    <configure
            ...        xmlns="http://namespaces.zope.org/zope"
            ...        >
            ...
            ...      <unauthenticatedGroup
            ...         id="zope.unknowngroup"
            ...         title="Anonymous users"
            ...         description="People we don't know"
            ...         />
            ...
            ...    </configure>
            ... """)
        
        This directive creates a group and registers it as a utility providing
        IUnauthenticatedGroup:
        
            >>> g = component.getUtility(interfaces.IUnauthenticatedGroup)
            >>> g.id, g.title, g.description
            ('zope.unknowngroup', u'Anonymous users', u"People we don't know")
        
        The unauthenticatedGroup directive also updates the group of the
        unauthenticated principal:
        
            >>> p = principalRegistry.unauthenticatedPrincipal()
            >>> g.id in p.groups
            True
            >>> p = component.getUtility(interfaces.IUnauthenticatedPrincipal)
            >>> g.id in p.groups
            True
        
        If the unauthenticated principal is defined after the unauthenticated
        group, it will likewise have the group added to it:
        
            >>> reset()
            >>> zcml("""
            ...    <configure xmlns="http://namespaces.zope.org/zope">
            ...
            ...      <unauthenticatedGroup
            ...         id="zope.unknowngroup2"
            ...         title="Anonymous users"
            ...         description="People we don't know"
            ...         />
            ...      <unauthenticatedPrincipal
            ...         id="zope.unknown2"
            ...         title="Anonymous user"
            ...         description="A person we don't know"
            ...         />
            ...
            ...    </configure>
            ... """)
        
            >>> g = component.getUtility(interfaces.IUnauthenticatedGroup)
            >>> g.id, g.title, g.description
            ('zope.unknowngroup2', u'Anonymous users', u"People we don't know")
            >>> p = principalRegistry.unauthenticatedPrincipal()
            >>> p.id, g.id in p.groups
            ('zope.unknown2', True)
            >>> p = component.getUtility(interfaces.IUnauthenticatedPrincipal)
            >>> p.id, g.id in p.groups
            ('zope.unknown2', True)
        
        The unauthenticated group shows up as a principal in the principal
        registry:
        
            >>> principalRegistry.getPrincipal(g.id) == g
            True
        
            >>> list(principalRegistry.getPrincipals("Anonymous")) == [g]
            True
        
        The authenticated group
        -----------------------
        
        There is an authenticated group:
        
            >>> reset()
            >>> zcml("""
            ...    <configure xmlns="http://namespaces.zope.org/zope">
            ...
            ...      <unauthenticatedPrincipal
            ...         id="zope.unknown3"
            ...         title="Anonymous user"
            ...         description="A person we don't know"
            ...         />
            ...      <principal
            ...         id="zope.manager2"
            ...         title="Manager"
            ...         description="System Manager"
            ...         login="admin"
            ...         password="123"
            ...         />
            ...      <authenticatedGroup
            ...         id="zope.authenticated"
            ...         title="Authenticated users"
            ...         description="People we know"
            ...         />
            ...      <principal
            ...         id="zope.manager3"
            ...         title="Manager 3"
            ...         login="admin3"
            ...         password="123"
            ...         />
            ...
            ...    </configure>
            ... """)
        
        It defines an IAuthenticatedGroup utility:
        
            >>> g = component.getUtility(interfaces.IAuthenticatedGroup)
            >>> g.id, g.title, g.description
            ('zope.authenticated', u'Authenticated users', u'People we know')
        
        It also adds it self to the groups of any non-group principals already
        defined, and, when non-group principals are defined, they put
        themselves in the group if it's defined:
        
            >>> principals = list(principalRegistry.getPrincipals(''))
            >>> principals.sort(lambda p1, p2: cmp(p1.id, p2.id))
            >>> for p in principals:
            ...    print p.id, p.groups == [g.id]
            zope.authenticated False
            zope.manager2 True
            zope.manager3 True
        
        Excluding unauthenticated principals, of course:
        
            >>> p = principalRegistry.unauthenticatedPrincipal()
            >>> p.id, g.id in p.groups
            ('zope.unknown3', False)
            >>> p = component.getUtility(interfaces.IUnauthenticatedPrincipal)
            >>> p.id, g.id in p.groups
            ('zope.unknown3', False)
        
        
        The everybody group
        -------------------
        
        Finally, there is an everybody group:
        
            >>> reset()
            >>> zcml("""
            ...    <configure xmlns="http://namespaces.zope.org/zope">
            ...
            ...      <unauthenticatedPrincipal
            ...         id="zope.unknown4"
            ...         title="Anonymous user"
            ...         description="A person we don't know"
            ...         />
            ...      <principal
            ...         id="zope.manager4"
            ...         title="Manager"
            ...         description="System Manager"
            ...         login="admin"
            ...         password="123"
            ...         />
            ...      <everybodyGroup
            ...         id="zope.everybody"
            ...         title="Everybody"
            ...         description="All People"
            ...         />
            ...      <principal
            ...         id="zope.manager5"
            ...         title="Manager 5"
            ...         login="admin5"
            ...         password="123"
            ...         />
            ...
            ...    </configure>
            ... """)
        
        The everybodyGroup directive defines an IEveryoneGroup utility:
        
            >>> g = component.getUtility(interfaces.IEveryoneGroup)
            >>> g.id, g.title, g.description
            ('zope.everybody', u'Everybody', u'All People')
        
        It also adds it self to the groups of any non-group principals already
        defined, and, when non-group principals are defined, they put
        themselves in the group if it's defined:
        
            >>> principals = list(principalRegistry.getPrincipals(''))
            >>> principals.sort(lambda p1, p2: cmp(p1.id, p2.id))
            >>> for p in principals:
            ...    print p.id, p.groups == [g.id]
            zope.everybody False
            zope.manager4 True
            zope.manager5 True
        
        Including unauthenticated principals, of course:
        
            >>> p = principalRegistry.unauthenticatedPrincipal()
            >>> p.id, g.id in p.groups
            ('zope.unknown4', True)
            >>> p = component.getUtility(interfaces.IUnauthenticatedPrincipal)
            >>> p.id, g.id in p.groups
            ('zope.unknown4', True)
        
        Note that it is up to IAuthentication implementations to associate
        these groups with their principals, as appropriate.
        
        
        The system_user
        ---------------
        
        There is also a system_user that is defined in the code.  It will be returned
        from the getPrincipal method of the registry.
        
            >>> import zope.security.management
            >>> import zope.principalregistry.principalregistry
            >>> auth = zope.principalregistry.principalregistry.PrincipalRegistry()
            >>> system_user = auth.getPrincipal(u'zope.security.management.system_user')
            >>> system_user is zope.security.management.system_user
            True

        CHANGES
        =======
        
        3.7.1 (2010-09-25)
        ------------------
        
        - Added test extra to declare test dependency on ``zope.component [test]``.
        
        - Using Python's ``doctest`` module instead of depreacted
          ``zope.testing.doctest``.
        
        
        3.7.0 (2009-03-14)
        ------------------
        
        - Removed ``zope.container`` dependency, as contained principals didn't make any
          sense, since PrincipalRegistry never provided IContainer. Also, zope.container
          pulls a number dependencies, that are not needed for non-persistent principal
          registry (like, ZCML, for example).
        
          Set __name__ and __parent__ by hand to provide some backward-compatibility and
          to save a pointer to registry from principal objects.
        
        - Initial release. This package was splitted from zope.app.security as a part
          of the refactoring process to provide global principal registry without extra
          dependencies.
