6 * This is a complete OOP rewrite of the old WikiUser code with various
7 * configurable external authentication methods.
9 * There's only one entry point, the function WikiUser which returns
10 * a WikiUser object, which contains the user's preferences.
11 * This object might get upgraded during the login step and later also.
12 * There exist three preferences storage methods: cookie, homepage and db,
13 * and multiple password checking methods.
14 * See index.php for $USER_AUTH_ORDER[] and USER_AUTH_POLICY if
15 * ALLOW_USER_PASSWORDS is defined.
17 * Each user object must define the two preferences methods
18 * getPreferences(), setPreferences(),
19 * and the following 1-4 auth methods
20 * checkPass() must be defined by all classes,
21 * userExists() only if USER_AUTH_POLICY'=='strict'
22 * mayChangePass() only if the password is storable.
23 * storePass() only if the password is storable.
25 * WikiUser() given no name, returns an _AnonUser (anonymous user)
26 * object, who may or may not have a cookie.
27 * However, if the there's a cookie with the userid or a session,
28 * the user is upgraded to the matching user object.
29 * Given a user name, returns a _BogoUser object, who may or may not
30 * have a cookie and/or PersonalPage, one of the various _PassUser objects
31 * or an _AdminUser object.
32 * BTW: A BogoUser is a userid (loginname) as valid WikiWord, who might
33 * have stored a password or not. If so, his account is secure, if not
34 * anybody can use it, because the username is visible e.g. in RecentChanges.
36 * Takes care of passwords, all preference loading/storing in the
37 * user's page and any cookies. lib/main.php will query the user object to
38 * verify the password as appropriate.

43 * Notes by 2004-01-25 03:43:45 rurban
44 * Test it by defining ENABLE_USER_NEW in index.php
45 * 1) Now a ForbiddenUser is returned instead of false.
46 * 2) Previously ALLOW_ANON_USER = false meant that anon users cannot edit,
47 * but may browse. Now with ALLOW_ANON_USER = false he may not browse,
48 * which is needed to disable browse PagePermissions.
49 * I added now ALLOW_ANON_EDIT = true to makes things clear.
50 * (which replaces REQUIRE_SIGNIN_BEFORE_EDIT)
52 * 3) Removed pear prepare. Performance hog, and using integers as
53 * handler doesn't help. Do simple sprintf as with adodb. And a prepare
54 * in the object init is no advantage, because in the init loop a lot of
55 * objects are tried, but not used.
56 * 4) Already gotten prefs are passed to the next object to avoid
57 * duplicate getPreferences() calls.
58 * 2004-03-18 17:32:21 rurban
59 * 5) Major php-5 problem: $this re-assignment is disallowed by the parser
60 * So we cannot just discrimate with
61 * if (!check_php_version(5))
64 * 6) enforced new cookie policy: prefs don't get stored in cookies
65 * anymore, only in homepage and/or database, but always in the
66 * current session. old pref cookies will get deleted.

2819 // * added $user->_userid and class '_WikiUser' portability functions
2820 // * fixed $user object ->_level upgrading, mostly using sessions.
2821 // this fixes yesterdays problems with loosing authorization level.

2830 // Revision 1.5 2004/01/25 03:05:00 rurban
2831 // First working version, but has some problems with the current main loop.
2832 // Implemented new auth method dispatcher and policies, all the external
2833 // _PassUser classes (also for ADODB and Pear DB).
2834 // The two global funcs UserExists() and CheckPass() are probably not needed,
2835 // since the auth loop is done recursively inside the class code, upgrading
2836 // the user class within itself.
2837 // Note: When a higher user class is returned, this doesn't mean that the user
2838 // is authorized, $user->_level is still low, and only upgraded on successful
2841 // Revision 1.4 2003/12/07 19:29:48 carstenklapp
2842 // Code Housecleaning: fixed syntax errors. (php -l *.php)
2844 // Revision 1.3 2003/12/06 19:10:46 carstenklapp
2845 // Finished off logic for determining user class, including
2846 // PassUser. Removed ability of BogoUser to save prefs into a page.
2848 // Revision 1.2 2003/12/03 21:45:48 carstenklapp
2849 // Added admin user, password user, and preference classes. Added
2850 // password checking functions for users and the admin. (Now the easy
2851 // parts are nearly done).
2853 // Revision 1.1 2003/12/02 05:46:36 carstenklapp
2854 // Complete rewrite of WikiUser.php.
2856 // This should make it easier to hook in user permission groups etc. some
2857 // time in the future. Most importantly, to finally get UserPreferences
2858 // fully working properly for all classes of users: AnonUser, BogoUser,
2859 // AdminUser; whether they have a NamesakePage (PersonalHomePage) or not,
2860 // want a cookie or not, and to bring back optional AutoLogin with the
2861 // UserName stored in a cookie--something that was lost after PhpWiki had
2862 // dropped the default http auth login method.
2864 // Added WikiUser classes which will (almost) work together with existing
2865 // UserPreferences class. Other parts of PhpWiki need to be updated yet
2866 // before this code can be hooked up.
