22 * This is a complete OOP rewrite of the old WikiUser code with various
23 * configurable external authentication methods.
25 * There's only one entry point, the function WikiUser which returns
26 * a WikiUser object, which contains the name, authlevel and user's preferences.
27 * This object might get upgraded during the login step and later also.
28 * There exist three preferences storage methods: cookie, homepage and db,
29 * and multiple password checking methods.
30 * See index.php for $USER_AUTH_ORDER[] and USER_AUTH_POLICY if
31 * ALLOW_USER_PASSWORDS is defined.
33 * Each user object must define the two preferences methods
34 * getPreferences(), setPreferences(),
35 * and the following 1-4 auth methods
36 * checkPass() must be defined by all classes,
37 * userExists() only if USER_AUTH_POLICY'=='strict'
38 * mayChangePass() only if the password is storable.
39 * storePass() only if the password is storable.
41 * WikiUser() given no name, returns an _AnonUser (anonymous user)
42 * object, who may or may not have a cookie.
43 * However, if the there's a cookie with the userid or a session,
44 * the user is upgraded to the matching user object.
45 * Given a user name, returns a _BogoUser object, who may or may not
46 * have a cookie and/or PersonalPage, one of the various _PassUser objects
47 * or an _AdminUser object.
48 * BTW: A BogoUser is a userid (loginname) as valid WikiWord, who might
49 * have stored a password or not. If so, his account is secure, if not
50 * anybody can use it, because the username is visible e.g. in RecentChanges.
52 * Takes care of passwords, all preference loading/storing in the
53 * user's page and any cookies. lib/main.php will query the user object to
54 * verify the password as appropriate.
56 * @author: Reini Urban (the tricky parts),
57 * Carsten Klapp (started rolling the ball)
59 * Random architectural notes, sorted by date:
61 * Test it by defining ENABLE_USER_NEW in config/config.ini
62 * 1) Now a ForbiddenUser is returned instead of false.
63 * 2) Previously ALLOW_ANON_USER = false meant that anon users cannot edit,
64 * but may browse. Now with ALLOW_ANON_USER = false he may not browse,
65 * which is needed to disable browse PagePermissions.
66 * I added now ALLOW_ANON_EDIT = true to makes things clear.
67 * (which replaces REQUIRE_SIGNIN_BEFORE_EDIT)
69 * 3) Removed pear prepare. Performance hog, and using integers as
70 * handler doesn't help. Do simple sprintf as with adodb. And a prepare
71 * in the object init is no advantage, because in the init loop a lot of
72 * objects are tried, but not used.
73 * 4) Already gotten prefs are passed to the next object to avoid
74 * duplicate getPreferences() calls.
76 * 5) Major php-5 problem: $this re-assignment is disallowed by the parser
77 * So we cannot just discrimate with
78 * if (!check_php_version(5))
80 * A /php5-patch.php is provided, which patches the src automatically
81 * for php4 and php5. Default is php4.
83 * 6) enforced new cookie policy: prefs don't get stored in cookies
84 * anymore, only in homepage and/or database, but always in the
85 * current session. old pref cookies will get deleted.
87 * 7) Certain themes should be able to extend the predefined list
88 * of preferences. Display/editing is done in the theme specific userprefs.tmpl,
89 * but storage must be extended to the Get/SetPreferences methods.
90 * <theme>/themeinfo.php must provide CustomUserPreferences:
91 * A list of name => _UserPreference class pairs.

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.

3455 // Revision 1.13 2004/02/09 03:58:12 rurban
3456 // for now default DB_SESSION to false
3458 // * not existing perms will now query the parent, and not
3459 // return the default perm
3460 // * added pagePermissions func which returns the object per page
3461 // * added getAccessDescription
3463 // * added global ->prepare (not yet used) with smart user/pref/member table prefixing.
3464 // * force init of authdbh in the 2 db classes
3466 // * fixed session handling (not triple auth request anymore)
3467 // * don't store cookie prefs with sessions
3468 // stdlib: global obj2hash helper from _AuthInfo, also needed for PagePerm

3477 // LDAP cleanup, start of new Pref classes
3479 // Revision 1.10 2004/02/01 09:14:11 rurban
3480 // Started with Group_Ldap (not yet ready)
3481 // added new _AuthInfo plugin to help in auth problems (warning: may display passwords)
3482 // fixed some configurator vars
3483 // renamed LDAP_AUTH_SEARCH to LDAP_BASE_DN
3484 // changed PHPWIKI_VERSION from 1.3.8a to 1.3.8pre
3485 // USE_DB_SESSION defaults to true on SQL
3486 // changed GROUP_METHOD definition to string, not constants
3487 // changed sample user DBAuthParams from UPDATE to REPLACE to be able to
3488 // create users. (Not to be used with external databases generally, but
3489 // with the default internal user table)
3491 // fixed the IndexAsConfigProblem logic. this was flawed:
3492 // scripts which are the same virtual path defined their own lib/main call
3493 // (hmm, have to test this better, phpwiki.sf.net/demo works again)
3495 // Revision 1.9 2004/01/30 19:57:58 rurban

3499 // fix "lib/WikiUserNew.php:572: Notice[8]: Undefined variable: DBParams"
3501 // Revision 1.7 2004/01/27 23:23:39 rurban

3503 // renamed mayCheckPassword => mayCheckPass
3504 // fixed recursion problem in WikiUserNew
3505 // fixed bogo login (but not quite 100% ready yet, password storage)
3507 // Revision 1.6 2004/01/26 09:17:49 rurban
3508 // * changed stored pref representation as before.
3509 // the array of objects is 1) bigger and 2)
3510 // less portable. If we would import packed pref
3511 // objects and the object definition was changed, PHP would fail.
3512 // This doesn't happen with an simple array of non-default values.
3513 // * use $prefs->retrieve and $prefs->store methods, where retrieve
3514 // understands the interim format of array of objects also.
3515 // * simplified $prefs->get() and fixed $prefs->set()
3516 // * added $user->_userid and class '_WikiUser' portability functions
3517 // * fixed $user object ->_level upgrading, mostly using sessions.
3518 // this fixes yesterdays problems with loosing authorization level.
3519 // * fixed WikiUserNew::checkPass to return the _level
3520 // * fixed WikiUserNew::isSignedIn
3521 // * added explodePageList to class PageList, support sortby arg
3522 // * fixed UserPreferences for WikiUserNew
3523 // * fixed WikiPlugin for empty defaults array
3524 // * UnfoldSubpages: added pagename arg, renamed pages arg,
3525 // removed sort arg, support sortby arg
3527 // Revision 1.5 2004/01/25 03:05:00 rurban
3528 // First working version, but has some problems with the current main loop.
3529 // Implemented new auth method dispatcher and policies, all the external
3530 // _PassUser classes (also for ADODB and Pear DB).
3531 // The two global funcs UserExists() and CheckPass() are probably not needed,
3532 // since the auth loop is done recursively inside the class code, upgrading
3533 // the user class within itself.
3534 // Note: When a higher user class is returned, this doesn't mean that the user
3535 // is authorized, $user->_level is still low, and only upgraded on successful
3538 // Revision 1.4 2003/12/07 19:29:48 carstenklapp
3539 // Code Housecleaning: fixed syntax errors. (php -l *.php)
3541 // Revision 1.3 2003/12/06 19:10:46 carstenklapp
3542 // Finished off logic for determining user class, including
3543 // PassUser. Removed ability of BogoUser to save prefs into a page.
3545 // Revision 1.2 2003/12/03 21:45:48 carstenklapp
3546 // Added admin user, password user, and preference classes. Added
3547 // password checking functions for users and the admin. (Now the easy
3548 // parts are nearly done).
3550 // Revision 1.1 2003/12/02 05:46:36 carstenklapp
3551 // Complete rewrite of WikiUser.php.
3553 // This should make it easier to hook in user permission groups etc. some
3554 // time in the future. Most importantly, to finally get UserPreferences
3555 // fully working properly for all classes of users: AnonUser, BogoUser,
3556 // AdminUser; whether they have a NamesakePage (PersonalHomePage) or not,
3557 // want a cookie or not, and to bring back optional AutoLogin with the
3558 // UserName stored in a cookie--something that was lost after PhpWiki had
3559 // dropped the default http auth login method.
3561 // Added WikiUser classes which will (almost) work together with existing
3562 // UserPreferences class. Other parts of PhpWiki need to be updated yet
3563 // before this code can be hooked up.
