      Hi Ken,

        Below goes the telemetry for the relevant part. What I see here
        is that Cyrus correctly answers to the "principal?" question and
        then the iOS asks for calendars of the principal (telemetry
        included in the attached file) and there Cyrus only returns the
        personal calendars, but IMO the shared folder should be somehow
        taken into account, either responding differently to the
        "principal?" question or including the shared calendar when
        queried for available calendars (IMO the best solution (no need
        to create separate accounts on the phone with different URLs).

        Please let me know if you need additional details.

        Regards,

        Anatoli

    Can you capture telemetry for the PROPFIND and OPTIONS requests
      on the shared calendar?

        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:

          But finally, iPhone Calendar app doesn't show events from the

          naked domain (i.e. without the /dav/calendars/shared/
          part). What could be done to make it work?

            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.

            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)

          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
