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.

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.

3437 // Revision 1.13 2004/02/09 03:58:12 rurban
3438 // for now default DB_SESSION to false
3440 // * not existing perms will now query the parent, and not
3441 // return the default perm
3442 // * added pagePermissions func which returns the object per page
3443 // * added getAccessDescription
3445 // * added global ->prepare (not yet used) with smart user/pref/member table prefixing.
3446 // * force init of authdbh in the 2 db classes
3448 // * fixed session handling (not triple auth request anymore)
3449 // * don't store cookie prefs with sessions
3450 // stdlib: global obj2hash helper from _AuthInfo, also needed for PagePerm

3459 // LDAP cleanup, start of new Pref classes
3461 // Revision 1.10 2004/02/01 09:14:11 rurban
3462 // Started with Group_Ldap (not yet ready)
3463 // added new _AuthInfo plugin to help in auth problems (warning: may display passwords)
3464 // fixed some configurator vars
3465 // renamed LDAP_AUTH_SEARCH to LDAP_BASE_DN
3466 // changed PHPWIKI_VERSION from 1.3.8a to 1.3.8pre
3467 // USE_DB_SESSION defaults to true on SQL
3468 // changed GROUP_METHOD definition to string, not constants
3469 // changed sample user DBAuthParams from UPDATE to REPLACE to be able to
3470 // create users. (Not to be used with external databases generally, but
3471 // with the default internal user table)
3473 // fixed the IndexAsConfigProblem logic. this was flawed:
3474 // scripts which are the same virtual path defined their own lib/main call
3475 // (hmm, have to test this better, phpwiki.sf.net/demo works again)
3477 // Revision 1.9 2004/01/30 19:57:58 rurban
3478 // fixed DBAuthParams['pref_select']: wrong _auth_dbi object used.
3480 // Revision 1.8 2004/01/30 18:46:15 rurban
3481 // fix "lib/WikiUserNew.php:572: Notice[8]: Undefined variable: DBParams"
3483 // Revision 1.7 2004/01/27 23:23:39 rurban

3485 // renamed mayCheckPassword => mayCheckPass
3486 // fixed recursion problem in WikiUserNew
3487 // fixed bogo login (but not quite 100% ready yet, password storage)
3489 // Revision 1.6 2004/01/26 09:17:49 rurban
3490 // * changed stored pref representation as before.
3491 // the array of objects is 1) bigger and 2)
3492 // less portable. If we would import packed pref
3493 // objects and the object definition was changed, PHP would fail.
3494 // This doesn't happen with an simple array of non-default values.
3495 // * use $prefs->retrieve and $prefs->store methods, where retrieve
3496 // understands the interim format of array of objects also.
3497 // * simplified $prefs->get() and fixed $prefs->set()
3498 // * added $user->_userid and class '_WikiUser' portability functions
3499 // * fixed $user object ->_level upgrading, mostly using sessions.
3500 // this fixes yesterdays problems with loosing authorization level.
3501 // * fixed WikiUserNew::checkPass to return the _level
3502 // * fixed WikiUserNew::isSignedIn
3503 // * added explodePageList to class PageList, support sortby arg
3504 // * fixed UserPreferences for WikiUserNew
3505 // * fixed WikiPlugin for empty defaults array
3506 // * UnfoldSubpages: added pagename arg, renamed pages arg,
3507 // removed sort arg, support sortby arg
3509 // Revision 1.5 2004/01/25 03:05:00 rurban
3510 // First working version, but has some problems with the current main loop.
3511 // Implemented new auth method dispatcher and policies, all the external
3512 // _PassUser classes (also for ADODB and Pear DB).
3513 // The two global funcs UserExists() and CheckPass() are probably not needed,
3514 // since the auth loop is done recursively inside the class code, upgrading
3515 // the user class within itself.
3516 // Note: When a higher user class is returned, this doesn't mean that the user
3517 // is authorized, $user->_level is still low, and only upgraded on successful
3520 // Revision 1.4 2003/12/07 19:29:48 carstenklapp
3521 // Code Housecleaning: fixed syntax errors. (php -l *.php)
3523 // Revision 1.3 2003/12/06 19:10:46 carstenklapp
3524 // Finished off logic for determining user class, including
3525 // PassUser. Removed ability of BogoUser to save prefs into a page.
3527 // Revision 1.2 2003/12/03 21:45:48 carstenklapp
3528 // Added admin user, password user, and preference classes. Added
3529 // password checking functions for users and the admin. (Now the easy
3530 // parts are nearly done).
3532 // Revision 1.1 2003/12/02 05:46:36 carstenklapp
3533 // Complete rewrite of WikiUser.php.
3535 // This should make it easier to hook in user permission groups etc. some
3536 // time in the future. Most importantly, to finally get UserPreferences
3537 // fully working properly for all classes of users: AnonUser, BogoUser,
3538 // AdminUser; whether they have a NamesakePage (PersonalHomePage) or not,
3539 // want a cookie or not, and to bring back optional AutoLogin with the
3540 // UserName stored in a cookie--something that was lost after PhpWiki had
3541 // dropped the default http auth login method.
3543 // Added WikiUser classes which will (almost) work together with existing
3544 // UserPreferences class. Other parts of PhpWiki need to be updated yet
3545 // before this code can be hooked up.
