4 // This is a complete OOP rewrite of the old WikiUser code with various
5 // configurable external authentification methods.
7 // There's only one entry point, the function WikiUser which returns
8 // a WikiUser object, which contains the user's preferences.
9 // This object might get upgraded during the login step and later also.
10 // There exist three preferences storage methods: cookie, homepage and db,
11 // and multiple password checking methods.
12 // See index.php for $USER_AUTH_ORDER[] and USER_AUTH_POLICY if
13 // ALLOW_USER_PASSWORDS is defined.
15 // Each user object must define the two preferences methods
16 // getPreferences(), setPreferences(),
17 // and the following 1-3 auth methods:
18 // checkPass() must be defined by all classes,
19 // userExists() only if USER_AUTH_POLICY'=='strict'
20 // mayChangePass() only if the password is storable.
21 // storePass() only if the password is storable.
23 // WikiUser() given no name, returns an _AnonUser (anonymous user)
24 // object, who may or may not have a cookie.
25 // However, if the there's a cookie with the userid or a session,
26 // the user is upgraded to the matching user object.
27 // Given a user name, returns a _BogoUser object, who may or may not
28 // have a cookie and/or PersonalPage, a _PassUser object or an
31 // Takes care of passwords, all preference loading/storing in the
32 // user's page and any cookies. lib/main.php will query the user object to
33 // verify the password as appropriate.

36 // Currently this library doesn't look good enough with
37 // the current configuration options.
38 // Test it by defining ENABLE_USER_NEW in index.php
39 // The problem is that the previous code was written to do auth checks
40 // only on action != browse, and this code requires a good enough
41 // user object even for browse. I don't think that this is a good idea.
42 // 1) Now a ForbiddenUser is returned instead of false.
43 // 2) Previously ALLOW_ANON_USER = false meant that anon users cannot edit,
44 // but may browse. Now with ALLOW_ANON_USER = false he may not browse,
45 // which is needed to disable browse PagePermissions. Hmm...
46 // I added now ALLOW_ANON_EDIT = true to makes things clear.
47 // (which replaces REQUIRE_SIGNIN_BEFORE_EDIT)

1803 // LDAP cleanup, start of new Pref classes
1805 // Revision 1.10 2004/02/01 09:14:11 rurban
1806 // Started with Group_Ldap (not yet ready)
1807 // added new _AuthInfo plugin to help in auth problems (warning: may display passwords)
1808 // fixed some configurator vars
1809 // renamed LDAP_AUTH_SEARCH to LDAP_BASE_DN
1810 // changed PHPWIKI_VERSION from 1.3.8a to 1.3.8pre
1811 // USE_DB_SESSION defaults to true on SQL
1812 // changed GROUP_METHOD definition to string, not constants
1813 // changed sample user DBAuthParams from UPDATE to REPLACE to be able to
1814 // create users. (Not to be used with external databases generally, but
1815 // with the default internal user table)

1839 // * use $prefs->retrieve and $prefs->store methods, where retrieve
1840 // understands the interim format of array of objects also.
1841 // * simplified $prefs->get() and fixed $prefs->set()
1842 // * added $user->_userid and class '_WikiUser' portability functions
1843 // * fixed $user object ->_level upgrading, mostly using sessions.
1844 // this fixes yesterdays problems with loosing authorization level.
1845 // * fixed WikiUserNew::checkPass to return the _level
1846 // * fixed WikiUserNew::isSignedIn
1847 // * added explodePageList to class PageList, support sortby arg
1848 // * fixed UserPreferences for WikiUserNew

1853 // Revision 1.5 2004/01/25 03:05:00 rurban
1854 // First working version, but has some problems with the current main loop.
1855 // Implemented new auth method dispatcher and policies, all the external
1856 // _PassUser classes (also for ADODB and Pear DB).
1857 // The two global funcs UserExists() and CheckPass() are probably not needed,
1858 // since the auth loop is done recursively inside the class code, upgrading
1859 // the user class within itself.
1860 // Note: When a higher user class is returned, this doesn't mean that the user
1861 // is authorized, $user->_level is still low, and only upgraded on successful

1867 // Revision 1.3 2003/12/06 19:10:46 carstenklapp
1868 // Finished off logic for determining user class, including
1869 // PassUser. Removed ability of BogoUser to save prefs into a page.
1871 // Revision 1.2 2003/12/03 21:45:48 carstenklapp
1872 // Added admin user, password user, and preference classes. Added
1873 // password checking functions for users and the admin. (Now the easy

1876 // Revision 1.1 2003/12/02 05:46:36 carstenklapp
1877 // Complete rewrite of WikiUser.php.
1879 // This should make it easier to hook in user permission groups etc. some
1880 // time in the future. Most importantly, to finally get UserPreferences
1881 // fully working properly for all classes of users: AnonUser, BogoUser,
1882 // AdminUser; whether they have a NamesakePage (PersonalHomePage) or not,
1883 // want a cookie or not, and to bring back optional AutoLogin with the
1884 // UserName stored in a cookie--something that was lost after PhpWiki had
1885 // dropped the default http auth login method.
1887 // Added WikiUser classes which will (almost) work together with existing
1888 // UserPreferences class. Other parts of PhpWiki need to be updated yet
1889 // before this code can be hooked up.
