Moodle 1.5.4 - yay!

I'm in a rush, unfortunately, but here are Martin Langhoff's auto-generated
change list items integrated into the other stuff. It's not pretty but it's probably getting close to complete.

-QUICK INSTALL

-
-For the impatient, here is a basic outline of the 
-installation process, which normally takes me only 
-a few minutes:
-
-1) Move the Moodle files into your web directory. 
-
-2) Create a single database for Moodle to store all
-   it's tables in (or choose an existing database).
-
-3) Visit your Moodle site with a browser, you should 
-   be taken to the install.php script, which will lead
-   you through creating a config.php file and then 
-   setting up Moodle, creating an admin account etc.
-
-4) Set up a cron task to call the file admin/cron.php
-   every five minutes or so.
-
-
-For more information, see the INSTALL DOCUMENTATION:

-A local copy can also be found in

-    * 1) Fixed bug 5745 reported by Harry Smith so now can edit en_utf8_local pack
-    * 2) More notification messages included
-    *
-    * 2006/05/30 mudrd8mz
-    * Merged with version by Mitsuhiro Yoshida - display icon links instead of text links
-    * (I have changed the position of arrow icons to not to be so close each other)
-    *
-    * 2006/05/19 mudrd8mz
-    * A lot of changes to support translation of *_utf8_local langugage packs. Needs testing
-    *
-    * 2006/05/16 mudrd8mz
-    * 1) LANG_DEFAULT_FILE can be now set. moodle.php used to be opened automatically.
-    *    As it was (and still is) one of the biggest files it usually took a long time to load the page
-    *    even if you just want to choose the file to translate.
-    * 2) added links from "missing" to "compare" mode page
-    * 3) english strings are now key-sorted in "missing" mode
-    * 4) list of files with missing strings is now displayed at the top of "missing" page
-    *
-    * 2006/05/14 mudrd8mz Improvements of lang.php,v 1.65 2006/04/10 22:15:57 stronk7 Exp 
-    *  1) "go to first missing string" link can be displayed (see LANG_DISPLAY_MISSING_LINKS)
-    *  2) "go to next missing" link can be displayed (see LANG_DISPLAY_MISSING_LINKS)
-    *  3) submit button may be repeated (see LANG_SUBMIT_REPEAT*)
-    *  4) added (empty) "summary" attribute for the <table>'s
-    *  5) added error_reporting(E_ALL ^ E_NOTICE); in "compare" mode (even in debug environment
-    *     we know that missing keys are missing strings here, not bugs ;-)

-/** auth_db_sync_users.php
- * 
- * This script is meant to be called from a cronjob to sync moodle with the LDAP 
- * backend in those setups where the LDAP backend acts as 'master'.
- * 
- * Recommended cron entry:
- * # 5 minutes past 4am
- * 5 4 * * * /usr/bin/php -c /etc/php4/cli/php.ini /var/www/moodle/auth/db/auth_db_sync_users.php
- * 
- * Notes: 
- *   - If you have a large number of users, you may want to raise the memory limits
- *     by passing -d memory_limit=256M
- *   - For debugging & better logging, you are encouraged to use in the command line:
- *     -d log_errors=1 -d error_reporting=E_ALL -d display_errors=0 -d html_errors=0
- *     
- * Performance notes:
- * + The code is simpler, but not as optimized as its LDAP counterpart.

 Moodle Configuration with Shibboleth only login
 -------------------------------------------------------------------------------
 If you want Shibboleth as your only authentication method, configure Moodle as
 described in the dual login section above and do the following steps:

-4.a  On the Moodle Shibboleth settings page, set the 'Alternate Login URL' to 
-     the URL of the file 'moodle/auth/shibboleth/index.php'
+5.a  On the Moodle Shibboleth settings page, set the 'Alternate Login URL' to

     This will enforce Shibboleth login.

 How the Shibboleth authentication works
 --------------------------------------------------------------------------------
-To get Shibboleth authenticated in Moodle a user basically must access the 
-Shibboleth-protected page /auth/shibboleth/index.php. If Shibboleth is the only 
-authentication method (see 4.a), this happens automatically when a user wants to 
-login in Moodle. Otherwise, the user has to click on the link on the login page 
-you provided in step 4.
+For a user to get Shibboleth authenticated in Moodle he first must go to the 
+Shibboleth-protected page shib-protected.php. If Shibboleth authentication is
+enabled this happens automatically when a user wants to login.
+Otherwise the user has to click on the link on the login page you provided in 
+step 5.

+If the user is successfully Shibboleth authenticated he is redirected to
+moodle/auth/shibboleth where he also gets authenticated in Moodle. 
 Moodle basically checks whether the Shibboleth attribute that you mapped
-as the username is present. This attribute should only be present if a user is 
+as the username is present. This attribute is only present if a user is 
 Shibboleth authenticated.

 If the user's Moodle account has not existed yet, it gets automatically created.
+Unless the user's firstname, last name and email address is provided, the user 
+is automatically redirected to the edit profile page by Moodle.

 To prevent that every Shibboleth user can access your Moodle site you have to
-adapt the 'require valid-user' line in your webserver's config  (see step 1) to 
-allow only specific users. If you defined some authorization rules in step 1,
-these are checked by Shibboleth itself. Only users who met these rules 
-actually can access /auth/shibboleth/index.php and get logged in.
+adapt the 'require valid-user' line in your webserver's config  (see step 2) to
