Could not access /webdav/

Hi All,
     I followed the instruction given at link
http://www.howtoforge.com/how-to-set-up-webdav-with-apache2-on-opensuse-11.2 to
set up WebDav with Apache2 on OpenSuse-11.2. Later, as given on tha same
page, I used *cadaver *to test WebDav during which I am getting following
error.
*   *
*   Could not access /webdav/ (not WebDAV-enabled?):*
*   405 Method Not Allowed*
*   Connection to `www.example1.com' closed.*

Could someone please help me to resolve the issue ?

Thanks
Shyam
