title: WebDAV on IIS 7.5 with SSL (self signed) - Windows can't connect - Mac can only mount it readonly
body: <p>Today I spent the whole day investigating why I have so many problems with WebDAV.</p>
  
  <p>My Server is running Windows 2008 R2 with IIS7.5.
  I created a self signed certificate and added it to the "Default Web Site". I enabled Windows Authentication and installed the WebDAV Extension.</p>
  
  <p>I enabled Locking WebDAV Settings as you see here:
  <a href="http://www.abload.de/img/webdavydkea.png" rel="nofollow">http://www.abload.de/img/webdavydkea.png</a></p>
  
  <p>I then created a folder called Shares on C:\ and changed added writting permissions for the domain users.</p>
  
  <p>At the end I created the Virtual Directory and set the "Authorization Rules" and the "WebDav Authorization Rules".</p>
  
  <p>At the end I force the usage of SSL with the previously self signed certificate.</p>
  
  <p>Now I try to connect with MAC OS X 10.7 and MAC OS X 10.6 and both mount it readonly.</p>
  
  <p>If I try to mount it in Windows I get the following error message:</p>
  
  <p>The mapped network drive could not be created because the following error has occurred:
  A device attached to the system is not functioning.</p>
  
  <p>More details if I try to mount it by using the command line:
  System error 1244 has occurred.
  The operation being requested was not performed because the user has not been authenticated.</p>
  
  <p>If I now disable the SSL support I can mount it in Windows too including write support. MAC OS X still does only mount it as read only.</p>
  
  <p>Altogether I have the following problems:</p>
  
  <ul>
  <li>Why does MAC OS X mount the WebDAV directory as readonly even so I enabled locking support?</li>
  <li>Why does Windows not work if I try to use SSL with the self signed certificate?</li>
  </ul>
