.htaccess on WebDAV

I am trying to edit my .htaccess file on WebDAV but I keep getting a 403 error.

I want to make my whole domain Webdav as described in http://wiki.dreamhost.com/WebDAV

If someone could please give me more information that would be great.

Per http://wiki.dreamhost.com/WebDAV#Step_3 are you putting the file quote[In the main folder for your domain]?
Or are you accidentally instead editing the .htaccess in the WebDAV root (a subfolder of that)?
