 From version 0.94 to 0.95
---------------------------

+Set your web server document root directory to ``www/``.
 
 Yes, we kind of lost the ability to run SemanticScuttle
 in a subdirectory of a hostname. This functionality will
 be back in one of the next releases, but for now, you have
 to live with it.
 
-Update your database:
-- ALTER TABLE `sc_bookmarks` ADD `bVoting` INT NOT NULL;
-- ALTER TABLE `sc_bookmarks` ADD `bVotes` INT NOT NULL;
-- Add the new votes database table. See data/tables.sql.
+Update your database
+--------------------
+Apply ``data/schema/4.sql``.
 
 Currently, only MySQL can be used as database backend.
 All other DBMS (database management systems) have not been
 tested except for PostgreSQL, and SemanticScuttle fails there.
 
-The de_AT translation has been re-added. This is because
-de_AT provides a rather ugly "official German" style,
-while the normal de_DE is friendlier. Choose what you like.

 - Nothing changed except for the default configuration file.
   It is recommended to start with a fresh config file,
   but not neccesary. Old config files still work.

+============================================
+External authentication with SemanticScuttle
+============================================
+
+Most times, one piece of software is only a part in the big puzzle
+that makes the software landscape of a company or organization.
+SemanticScuttle is not different and should integrate as nicely as
+possible with all other systems.
+
+One of the basic tasks of integration is user authentication against
+a central database - be it a central user database, an LDAP or a
+active directory server.
+
+Since version 0.96, SemanticScuttle supports user authentication against
+external systems. To provide a wide range of supported systems, we chose
+to utilize PEAR's `Authentication package`__.
+It does this by providing different "`authentication containers`__",
+for example Database, IMAP, LDAP, POP3, RADIUS, SAP and SOAP.
+
+Please be aware of the fact that, after successful authentication, the user
+and his scrambled password are stored in the SemanticScuttle database.
+This is required for proper functioning of the software. It does not mean
+that you will be able to login if your external authentication provider
+is offline - you won't, execpt you switch it off in the SemanticScuttle
+configuration.
+
+
+__ http://pear.php.net/package/Auth
+__ http://pear.php.net/manual/en/package.authentication.auth.intro-storage.php
+
+
+Basic configuration
+===================
+The default configuration file ``data/config.default.php`` has an own section
+on auth options and an explanation of the single entries.
+
+To utilize the external authentication, you need to install the
+PEAR Auth package: ::
+
+  $ pear install auth
+
+If you do not have a PEAR installation available, you can try to manually
+install the files in the src/ directory. If you choose to do that, the
+src/ directory should look similar to that: ::
+
+  src/
+   Auth.php
+   Auth/
+    Anonymous.php
+    Container.php
+    Container/
+    ..
+   SemanticScuttle/
+    header.php
+    ..
+
+After that, modify your ``data/config.php`` file. The most important change
+is to use ::
+
+  $serviceoverrides['User'] = 'SemanticScuttle_Service_AuthUser';
+
+which tells SemanticScuttle to switch to the special authentication service.
+
+Now that's done, you can configure the single auth options:
+
+``$authType = 'MDB2';``
+  selects the authentication container.
+
+``$authOptions``
+  is an array of options specific to the authentication container. Please
+  consult the PEAR Auth documentation for more information.
+
+``$authDebug = true;``
+  should be used when setup fails, since it may give important hints
+  where it fails.
+
+  Please note that login will seem to fail with
+  debugging activated. Going back to the main page after that will
+  show that you are logged in.
+
+
+
+Authentication examples
+=======================
+
+General database authentification
+---------------------------------
+Here you also need the PEAR `MDB2 package`_.
+The "``new_link``" option is important!
+
+``config.php`` settings: ::
+
+  $serviceoverrides['User'] = 'SemanticScuttle_Service_AuthUser';
+  $authType = 'MDB2';
+  $authOptions = array(
+      'dsn' => array(
+          'phptype'  => 'mysql',
+          'hostspec' => 'FIXME',
+          'username' => 'FIXME',
+          'password' => 'FIXME',
+          'database' => 'FIXME',
+          'new_link' => true,
+      ),
+      'table'       => 'usersFIXME',
+      'usernamecol' => 'usernameFIXME',
+      'passwordcol' => 'passwordFIXME',
+      'cryptType'   => 'md5',
+  );
+
+
+Mantis Bugtracker
+-----------------
+Here you also need the PEAR `MDB2 package`_.
+
+``config.php`` settings: ::
+
+  $serviceoverrides['User'] = 'SemanticScuttle_Service_AuthUser';
+  $authType = 'MDB2';
+  $authOptions = array(
+      'dsn' => array(
+          'phptype'  => 'mysql',
+          'hostspec' => 'FIXME',
+          'username' => 'FIXME',
+          'password' => 'FIXME',
+          'database' => 'FIXME',
+          'new_link' => true,
+      ),
+      'table'       => 'mantis_user_table',
+      'usernamecol' => 'username',
+      'passwordcol' => 'password',
+      'cryptType'   => 'md5',
+  );
+
+.. _MDB2 package: http://pear.php.net/package/MDB2
+
+
+MediaWiki
+---------
+Unfortunately, the password column does not contain a simple hashed
+password - for good reasons as described on
+http://www.mediawiki.org/wiki/Manual_talk:User_table#user_password_column
+
+If you configure your MediaWiki_ to use passwords without salt, you
+can make it work nevertheless:
+
+MediaWiki ``LocalSettings.php``: ::
+
+  $wgPasswordSalt = false;
+
+\- after that, users need to change/update their passwords to get them
+unsalted in the database. You can verify if the passwords are unhashed
+if you do ::
+
+  SELECT CAST( user_password AS CHAR ) FROM user
+
+on your MediaWiki database. Passwords prefixed with "``:A:``" can be used.
+
+Another problem is that mediawiki user names begin with an uppercase letter.
+You need to modify ``www/login.php`` and remove the "``utf8_strtolower``" function
+call: ::
+
+  $posteduser = trim(utf8_strtolower(POST_USERNAME));
+
+becomes ::
+
+  $posteduser = trim(POST_USERNAME);
+
+
+``config.php`` settings: ::
+
+  $serviceoverrides['User'] = 'SemanticScuttle_Service_AuthUser';
+  $authType = 'MDB2';
+  $authOptions = array(
+      'dsn' => array(
+          'phptype'  => 'mysql',
+          'hostspec' => 'FIXME',
+          'username' => 'FIXME',
+          'password' => 'FIXME',
+          'database' => 'FIXME',
+          'new_link' => true,
+      ),
+      'table'       => 'user',
+      'usernamecol' => 'user_name',
+      'passwordcol' => 'user_password',
+      'cryptType'   => 'md5_mediawiki',
+  );
+  function md5_mediawiki($password) {
+      return ':A:' . md5($password);
+  }
+
+
+.. _MediaWiki: http://www.mediawiki.org/wiki/MediaWiki
+
+Active Directory / LDAP
+-----------------------
+Here we authenticate against an active directory server.
+
+``config.php`` settings: ::
+
+  $serviceoverrides['User'] = 'SemanticScuttle_Service_AuthUser';
+  $authType = 'LDAP';
+  $authOptions = array(
+      'host'     => '192.168.1.4',
+      'version'  => 3,
+      'basedn'   => 'DC=EXAMPLE,DC=ORG',
+      'binddn'   => 'readuser',
+      'bindpw'   => 'readuser',
+      'userattr' => 'sAMAccountName',
+      'userfilter' => '(objectClass=user)',
+      'attributes' => array(''),

-Translating SemanticScuttle
-===========================
-
-SemanticScuttle uses gnu gettext for translation. It does not
-rely on the php extension but ships with a pure php implementation,
-php-gettext[1].
-
-Using gettext from within the code is really easy:
-Enclose the string you want to translate in a "T_" function call.
-
-For example, to translate
-> echo "Vote for";
-just write
-> echo T_("Vote for");
-
-
-Translation basics
-------------------
-

+===========================
+Translating SemanticScuttle
+===========================
+
+SemanticScuttle uses gnu gettext for translation. It does not
+rely on the php extension but ships with a pure php implementation,
+php-gettext_.
+
+Using gettext from within the code is really easy:
+Enclose the string you want to translate in a "``T_``" function call.
+
+For example, to translate::
+
+  echo "Vote for";
+
+just write ::
+
+  echo T_("Vote for");
+
+.. _php-gettext: https://launchpad.net/php-gettext/
+
+Translation basics
+==================
+
+We keep one base translation file, ``data/locales/messages.po``.
+This file is auto-generated via ``xgettext`` from all our php source files.
+In case you added a new string to the code that needs translation,
+update the base translation file by running ::
+
+  $ php scripts/update-translation-base.php
+
+After that has been done, the changes to the base ``messages.po`` file
+need to be merged into the single language translation files,
+for example ``data/locales/de_DE/LC_MESSAGES/messages.po``.
+
+Updating them from the master file is as easy as running::
+
+  $ php scripts/update-translation.php de_DE
+
+When the translation is ready, the ``.po`` file needs to be compiled
+in a machine-readable ``.mo`` file. Use ::
+
+  $ php scripts/compile-translation.php de_DE
+
+to achieve that.

+======================
+SemanticScuttle Themes
+======================
+SemanticScuttle may be changed visually by supplying custom "themes" (skins)
+that modify the visual appearance.
+
+
+Changing the current theme
+==========================
+In ``data/config.php``, set your theme like this: ::
+
+    $theme = 'darkmood';
+
+The available themes are the folders in ``www/themes/``.
+By default, SemanticScuttle ships only one usable theme ("default") and one
+to demonstrate how to create your own theme ("testdummy").
+
+
+Creating your own theme
+=======================
+Have a look at the "testdummy" theme in ``www/themes/testdummy/``.
+
+CSS and image files
+-------------------
+Since both file types need to be accessible via the web server directly,
+they are located in the ``www/`` folder: ::
+
+    www/themes/$themename/
+
+The main CSS file that automatically gets included is ::
+
+    www/themes/$themename/scuttle.css
+
+Several template files in SemanticScuttle include image files. If they do not
+exist in your theme, the default ones are used automatically.
+Note that this is not true for images that are specified in the CSS files.
+
+
+Template files
+--------------
+The templates of the default file are located in ::
+
+    data/templates/default/
+
+You may put your theme template files into ::
+
+    data/templates/$themename/
+
