24 Permissions per page and action based on current user,
25 ownership and group membership implemented with ACL's (Access Control Lists),
26 opposed to the simplier unix like ugo:rwx system.
27 The previous system was only based on action and current user. (lib/main.php)
29 Permissions may be inherited from its parent pages, a optional the
30 optional master page ("."), and predefined default permissions, if "."
32 Pagenames starting with "." have special default permissions.
33 For Authentication see WikiUserNew.php, WikiGroup.php and main.php
34 Page Permissions are in PhpWiki since v1.3.9 and enabled since v1.4.0
36 This file might replace the following functions from main.php:
37 Request::_notAuthorized($require_level)
38 display the denied message and optionally a login form
39 to gain higher privileges
40 Request::getActionDescription($action)
41 helper to localize the _notAuthorized message per action,
43 Request::getDisallowedActionDescription($action)
44 helper to localize the _notAuthorized message per action,
46 Request::requiredAuthority($action)
47 returns the needed user level
48 has a hook for plugins on POST
49 Request::requiredAuthorityForAction($action)
50 just returns the level per action, will be replaced with the
53 The defined main.php actions map to simplier access types:

854 // Slightly more elegant fix. Instead of WIKIAUTH_FORBIDDEN, the current user's level + 1 is returned on a false.
856 // Revision 1.9 2004/04/29 17:18:19 zorloc
857 // Fixes permission failure issues. With PagePermissions and Disabled Actions when user did not have permission WIKIAUTH_FORBIDDEN was returned. In WikiUser this was ok because WIKIAUTH_FORBIDDEN had a value of 11 -- thus no user could perform that action. But WikiUserNew has a WIKIAUTH_FORBIDDEN value of -1 -- thus a user without sufficent permission to do anything. The solution is a new high value permission level (WIKIAUTH_UNOBTAINABLE) to be the default level for access failure.

869 // special wikiunknown class with "?" and Tooltip.
870 // If true (default), any user will see the ?, but will be presented
871 // the PrintLoginForm on a click.
873 // Revision 1.6 2004/02/24 15:20:05 rurban
874 // fixed minor warnings: unchecked args, POST => Get urls for sortby e.g.
