How to share a calendar between users on Baikal?

Question

I have a Baikal server installed, I have two users: Bob and Alice. I want to share Bob's calendar with Alice.

I tried to go to my.baikal/dav.php/calendars/bob/calendar-to-share/ (which is the Sabre/Dav interface) and to give Alice access by using the Share this ressource form with no success.

I tried to use:

• Alice email: mailto:[email protected]
• Alice profile link: /dav.php/principals/alice

The d:invite node now looks like:

 <d:sharee>
  <d:href>/dav.php/principals/bob</d:href>
  <d:prop/>
  <d:share-access>
   <d:not-shared/>
  </d:share-access>
  <d:invite-accepted/>
 </d:sharee>
 <d:sharee>
  <d:href>/dav.php/principals/alice</d:href>
  <d:prop/>
  <d:share-access>
   <d:read-write/>
  </d:share-access>
  <d:invite-invalid/>
 </d:sharee>
 <d:sharee>
  <d:href>mailto:[email protected]</d:href>
  <d:prop/>
  <d:share-access>
   <d:read-write/>
  </d:share-access>
  <d:invite-accepted/>
 </d:sharee>

but Alice can't get access to Bob's calendar.
