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.
40 * @author: Reini Urban (the tricky parts),
41 * Carsten Klapp (started rolling the ball)
43 * Random architectural notes, sorted by date:
45 * Test it by defining ENABLE_USER_NEW in index.php
46 * 1) Now a ForbiddenUser is returned instead of false.
47 * 2) Previously ALLOW_ANON_USER = false meant that anon users cannot edit,
48 * but may browse. Now with ALLOW_ANON_USER = false he may not browse,
49 * which is needed to disable browse PagePermissions.
50 * I added now ALLOW_ANON_EDIT = true to makes things clear.
51 * (which replaces REQUIRE_SIGNIN_BEFORE_EDIT)
53 * 3) Removed pear prepare. Performance hog, and using integers as
54 * handler doesn't help. Do simple sprintf as with adodb. And a prepare
55 * in the object init is no advantage, because in the init loop a lot of
56 * objects are tried, but not used.
57 * 4) Already gotten prefs are passed to the next object to avoid
58 * duplicate getPreferences() calls.
60 * 5) Major php-5 problem: $this re-assignment is disallowed by the parser
61 * So we cannot just discrimate with
62 * if (!check_php_version(5))
64 * A /php5-patch.php is provided, which patches the src automatically
65 * for php4 and php5. Default is php4.
67 * 6) enforced new cookie policy: prefs don't get stored in cookies
68 * anymore, only in homepage and/or database, but always in the
69 * current session. old pref cookies will get deleted.
72 * Certain themes should be able to extend the predefined list
73 * of preferences. Display/editing is done in the theme specific userprefs.tmpl
74 * but storage must be extended to the Get/SetPreferences methods.
75 * <theme>/themeinfo.php must provide CustomUserPreferences:
76 * A list of name => _UserPreference class pairs.

2835 // update prefs only at UserPreferences POST (for testing)
2836 // unified db prefs methods (but in external pref classes yet)
2838 // Revision 1.13 2004/02/09 03:58:12 rurban
2839 // for now default DB_SESSION to false
2841 // * not existing perms will now query the parent, and not
2842 // return the default perm
2843 // * added pagePermissions func which returns the object per page
2844 // * added getAccessDescription
2846 // * added global ->prepare (not yet used) with smart user/pref/member table prefixing.
2847 // * force init of authdbh in the 2 db classes
2849 // * fixed session handling (not triple auth request anymore)
2850 // * don't store cookie prefs with sessions
2851 // stdlib: global obj2hash helper from _AuthInfo, also needed for PagePerm
2853 // Revision 1.12 2004/02/07 10:41:25 rurban
2854 // fixed auth from session (still double code but works)
2856 // fixed DbPassUser upgrade and policy=old
2859 // Revision 1.11 2004/02/03 09:45:39 rurban
2860 // LDAP cleanup, start of new Pref classes
2862 // Revision 1.10 2004/02/01 09:14:11 rurban
2863 // Started with Group_Ldap (not yet ready)
2864 // added new _AuthInfo plugin to help in auth problems (warning: may display passwords)
2865 // fixed some configurator vars
2866 // renamed LDAP_AUTH_SEARCH to LDAP_BASE_DN
2867 // changed PHPWIKI_VERSION from 1.3.8a to 1.3.8pre
2868 // USE_DB_SESSION defaults to true on SQL
2869 // changed GROUP_METHOD definition to string, not constants
2870 // changed sample user DBAuthParams from UPDATE to REPLACE to be able to
2871 // create users. (Not to be used with external databases generally, but
2872 // with the default internal user table)
2874 // fixed the IndexAsConfigProblem logic. this was flawed:
2875 // scripts which are the same virtual path defined their own lib/main call
2876 // (hmm, have to test this better, phpwiki.sf.net/demo works again)
2878 // Revision 1.9 2004/01/30 19:57:58 rurban
2879 // fixed DBAuthParams['pref_select']: wrong _auth_dbi object used.
2881 // Revision 1.8 2004/01/30 18:46:15 rurban
2882 // fix "lib/WikiUserNew.php:572: Notice[8]: Undefined variable: DBParams"
2884 // Revision 1.7 2004/01/27 23:23:39 rurban
2885 // renamed ->Username => _userid for consistency
2886 // renamed mayCheckPassword => mayCheckPass
2887 // fixed recursion problem in WikiUserNew
2888 // fixed bogo login (but not quite 100% ready yet, password storage)
2890 // Revision 1.6 2004/01/26 09:17:49 rurban
2891 // * changed stored pref representation as before.
2892 // the array of objects is 1) bigger and 2)
2893 // less portable. If we would import packed pref
2894 // objects and the object definition was changed, PHP would fail.
2895 // This doesn't happen with an simple array of non-default values.
2896 // * use $prefs->retrieve and $prefs->store methods, where retrieve
2897 // understands the interim format of array of objects also.
2898 // * simplified $prefs->get() and fixed $prefs->set()
2899 // * added $user->_userid and class '_WikiUser' portability functions
2900 // * fixed $user object ->_level upgrading, mostly using sessions.
2901 // this fixes yesterdays problems with loosing authorization level.
2902 // * fixed WikiUserNew::checkPass to return the _level
2903 // * fixed WikiUserNew::isSignedIn
2904 // * added explodePageList to class PageList, support sortby arg
2905 // * fixed UserPreferences for WikiUserNew
2906 // * fixed WikiPlugin for empty defaults array
2907 // * UnfoldSubpages: added pagename arg, renamed pages arg,
2908 // removed sort arg, support sortby arg
2910 // Revision 1.5 2004/01/25 03:05:00 rurban
2911 // First working version, but has some problems with the current main loop.
2912 // Implemented new auth method dispatcher and policies, all the external
2913 // _PassUser classes (also for ADODB and Pear DB).
2914 // The two global funcs UserExists() and CheckPass() are probably not needed,
2915 // since the auth loop is done recursively inside the class code, upgrading
2916 // the user class within itself.
2917 // Note: When a higher user class is returned, this doesn't mean that the user
2918 // is authorized, $user->_level is still low, and only upgraded on successful
2921 // Revision 1.4 2003/12/07 19:29:48 carstenklapp
2922 // Code Housecleaning: fixed syntax errors. (php -l *.php)
2924 // Revision 1.3 2003/12/06 19:10:46 carstenklapp
2925 // Finished off logic for determining user class, including
2926 // PassUser. Removed ability of BogoUser to save prefs into a page.
2928 // Revision 1.2 2003/12/03 21:45:48 carstenklapp
2929 // Added admin user, password user, and preference classes. Added
2930 // password checking functions for users and the admin. (Now the easy
2931 // parts are nearly done).
2933 // Revision 1.1 2003/12/02 05:46:36 carstenklapp
2934 // Complete rewrite of WikiUser.php.
2936 // This should make it easier to hook in user permission groups etc. some
2937 // time in the future. Most importantly, to finally get UserPreferences
2938 // fully working properly for all classes of users: AnonUser, BogoUser,
2939 // AdminUser; whether they have a NamesakePage (PersonalHomePage) or not,
2940 // want a cookie or not, and to bring back optional AutoLogin with the
2941 // UserName stored in a cookie--something that was lost after PhpWiki had
2942 // dropped the default http auth login method.
2944 // Added WikiUser classes which will (almost) work together with existing
2945 // UserPreferences class. Other parts of PhpWiki need to be updated yet
2946 // before this code can be hooked up.
