WebDAV ACL: Setting read permission on folder for principal

Question

I am attempting to give another principal read-permission to a WebDAV-folder I own. According to RFC3744 this should be possible using PROPPATCH, but only examples of PROPFIND are listed.

The only example I find is an example of how not to set owner (read-only property):

<propertyupdate xmlns="DAV:">
  <set>
    <prop>
      <owner>
        <href>principal_uri</href>
      </owner>
    </prop>
  </set>
</propertyupdate>

From that I've deduced this (failing) PROPPATCH:

<propertyupdate xmlns="DAV:">
  <set>
    <prop>
      <acl>
        <ace>
          <principal>
            <href>principal_uri</href>
          </principal>
          <grant>
            <privilege>
              <read/>
            </privilege>
          </grant>
        </ace>
      </acl>
    </prop>
  </set>
</propertyupdate>

I am doing this against Bedework 3.8 Calendar Server. It answers correctly to ACL-queries. The PROPPATCH above is responded with a 404 Not Found. Request is towards a valid URL.

Any suggestions would be very welcome.

Sincerely, Christian.

To update ACL's, you can't use PROPPATCH. You must use the ACL http method instead.
