      Hi Ken,

        
        Basically, the shared calendar is working fine in Thunderbird,
        where I can specify the exact URL. But I can't make it work on
        iPhone as it only takes the server and later resolves the exact
        URL via /.well-known/caldav which points to the personal
        calendar for the same user. Though, if I specify on iPhone the
        exact URL in the settings, it queries it:

        
        Mar 19 03:27:42 l https[18199]:
          [10.1.1.100] with "iOS/11.2.6 (15D100) dataaccessd/1.0";
          "PROPFIND /dav/calendars/shared/ HTTP/1.1" (depth=0) =>
          "HTTP/1.1 401 Unauthorized" (error=Must authenticate to access
          the specified target)

          "HTTP/1.1 207 Multi-Status"

          Mar 19 03:27:42 l https[18199]: login: [10.1.1.100] t2@xxxxxxx

          /dav/calendars/shared/ HTTP/1.1" => "HTTP/1.1 200 OK"

        
        But finally, iPhone Calendar app doesn't show events from the
        shared calendar and in the Accounts the URL resets to the naked
        domain (i.e. without the /dav/calendars/shared/
        part). What could be done to make it work?

        
        Thanks,

        Anatoli

        Ken,

          
          Thanks a lot! After creating the shared
          folder under the root hierarchy (with imtest -a admin and the command you provided),
          setting the corresponding ACLs for the users that have to have
          access to the folder (with cyradm
            sam) and creating a new connection in each WebDAV
          client for https://domain.com/dav/drive/shared/,
          everything worked fine!

          
          I'll try to test the same with CalDAV / CardDAV and report it
          here.

        
    Its entirely possible that the URL parsing code for CalDAV and
    CardDAV will not resolve to a shared folder.  Let me know.

    
          Regards,

          Hi
            Ken,

            
            Thanks for your quick reply. Yes, I'm willing to test it and
            if needed I can also apply patches (I build Cyrus from
            sources).

            
            > x CREATE shared (TYPE COLLECTION)

            
            What does this command is supposed to do and under what user
            should I execute it (I mean imtest
              -a <user>)? I tried to run it under admin
            user (it creates a "shared" folder at the root hierarchy)
            and under a normal user that already has a shared folder (in
            this case the folder is created under the user hierarchy),
            but in both cases the folder stays empty (with only
            cyrus.header and cyrus.index inside) and is not visible
            under a WebDAV client. Am I missing something?

          
      Definitely do this as an admin (e.g. 'cyrus') that DOES NOT have
      their own user hierarchy.

      
      Its been so long since I wrote and played with the WebDAV module
      that I forgot how it works.  Try:

      
      x CREATE #drive/shared (TYPE COLLECTION)

      
      Use whatever you have set for the davdriveprefix option and the
      proper hierarchy ('.' if you have disabled unixhierarchysep)

            Anatoli

        xDAV hasn't had much development or testing in the shared
          namespace and there isn't any tooling to create such
          mailboxes.
        If you wanted to do some testing, you'd have to create the
          mailboxes by hand and set the mailbox type accordingly.  To do
          so, you can connect to the server as an admin using imtest and
          enter the following command:
        x CREATE shared (TYPE COLLECTION)
        to create a WebDAV collection.  Or set the TYPE to CALENDAR
          or ADDRESSBOOK

          Hi All,

            
            I'm experimenting with xDav (CalDAV, CardDAV and WebDAV) in
            Cyrus 3.0.5. All xDAV services in user namespaces work as
            expected, but I can't figure out how to setup them for
            shared namespaces.

            
            The most important service for me to setup for shared
            namespaces is WebDAV. I'd like to have a shared folder
            accessible to multiple users based on their ACLs. I know how
            to setup a shared folder for IMAP:

            
            cyradm> cm shared1@xxxxxxxxxx

              cyradm> sam shared1@xxxxxxxxxx
              user1@xxxxxxxxxx
              write

            
            In the mail client I see the shared1 folder under "shared
            folders". But I can't see it in a WebDAV client. At the
            server the shared1 folder doesn't have the autocreated xDAV
            structure as it normally autocreates for individual users,
            and I don't know how to create it manually.

            
            Does anybody know how to configure WebDAV shared folders?
            I'm also interested in creating shared calendars (CalDAV)
            and addressbooks (CardDAV), but I suppose they are managed
            the same way as WebDAV.

            
            Thanks in advance,

            Anatoli
