[Using Sakai] WebDAV & Sakai

Using Mac OS 10.10.2:

1) Apple-K to connect to server
2) I paste in a QA DAV link
https://qa10-mysql.nightly.sakaiproject.org/dav/8d253f45-c6a7-4192-bcd1-b3d49731e49f
3) I login as instructor1 / sakai

The results are as expected. The disk is mounted, and I can open the text
files in a text editor, modify the file, and save.

If you can provide steps to replicate a bug on a sakaiproject.org QA
server, I'm willing to take a look.
