Windows authentication using apache and subversion

[Krishna Reddy <kr...@yahoo.com>]

Hello,
I installed apache, subversion and I configured them. I 
created repositories, gave username, password and 
permission to users. This is working well. Now I need to 
work on windows authentication which allows the user to 
change their password. I followed the material, found on 
Tortoise SVN. Iam enclosing the material which I followed 
for windows authentication. I used the SSPI for windows 
authentication. But, its not working. 
Please any one help for windows authentication.
Thank you.
