[CentOS] auth_changepassword

Dear All Friends,

i installed cacti on CentOS 6.2. every thing went smooth and i can see the
login page as well.

due to security reason cacti has to change the default password
(admin/admin) when i enter the default password i get the following error.

The requested URL /auth_changepassword.php was not found on this server.

Thanks / Regards
