Installing phpwiki with MS SQL Server Native Driver for ADOdb
-----------------------------------------------------------

Microsoft has been working hard to get support for their products
into Open Source projects. The MS SQL Server 2005 Driver for ADOdb
is one step in that direction. The following is instructions on how
to get and install the new mssql php driver for ADOdb as well as
how to get the new driver to work with phpWiki.

As of the writing of this walkthrough, the latest version of the PHP
driver for SQL Server 2005 is the May 2008 Community Technical Preview.
If you don't already have a copy of the SQL Server 2005 for PHP 
driver installed on your server, you can get a copy at:
http://www.microsoft.com/sql/technologies/php/default.mspx

This assumes that you have PHP 5 installed as well as a working copy of
any edition of SQL Server 2005 or SQL Server 2000 (including Express 
Edition). If you do not have a copy of the free SQL Server 2005 Express
Edition you can download it from:
http://go.microsoft.com/fwlink/?LinkId=64064

1. If you do not have a database created already, create one using
   the SQL Server Management tool. You can get the free Express version at:
   http://www.microsoft.com/downloads/details.aspx?FamilyId=C243A5AE-4BD1-
   4E3D-94B8-5A0F62BF7796&displaylang=en
   
2. If necessary create a user for that database which has the rights
   to select, insert, update, delete. For more information on how to use
   SQL Server 2005 you can download SQL Server 2005 Books Online at:
   http://www.microsoft.com/downloads/details.aspx?FamilyId=BE6A2C5D-00DF-
   4220-B133-29C1E0B6585F&displaylang=en

3. Create the tables and functions inside your database by running the SQL 
   file included with the phpWiki project located at: 
   schemas/sqlsrv-initialize.sql

4. Edit the DATABASE settings in config/config.ini to reflect your settings.

   a) DATABASE_TYPE should be set to 'ADODB' (case sensitive)
   b) DATABASE_DSN should be set to something like:
      'mssqlnative://username:password@pathtosqlserver/databasename'
   c) Note that if you set DATABASE_PREFIX to a non-empty string, you will 
	  have to edit schemas/sqlsrv-initialize.sql before you perform step
      three (above). You might also edit schemas/sqlsrv-destroy.sql at the 
	  same time, so you don't forget.
   d) USE_SAFE_DBSESSION should be set to 'true'
	
   Note: DATABASE_DIRECTORY and DATABASE_DBA_HANDLER are ignored for mssql.

That's it. phpWiki should work now.
