Hello, We're testing Cyrus3.0.9 in a murder configuration. It works fine for imap/imaps services. I can access mailboxes from differents frontend, and move mailboxes from on backend to another ! I'm now blocked with the calendar features in this configuration. It works fine in both read and write mode directly from the backend. http://backend.eurecom.fr/dav/calendars/user/xxxx/Default/ PUT /dav/calendars/user/xxxx/Default/8d6377bb-7c3f-4a55-a183-a05dae6fce0d.ics HTTP/1.1" (if-match="970dfe515581407e1f4eeaa887316530b3ef3020") => "HTTP/1.1 204 No Content" I've configured http/https also on the frontend to enable accessing calendars from there: http://frontend.eurecom.fr/dav/calendars/user/xxxx/Default/ It work perfectly in read only mode from the frontend, but if I try to do some changes, it does not complete with Forbidden message. "PUT /dav/calendars/user/xxxx/Default/8d6377bb-7c3f-4a55-a183-a05dae6fce0d.ics HTTP/1.1" (if-match="970dfe515581407e1f4eeaa887316530b3ef3020") => "HTTP/1.1 403 Forbidden" I've compiled backend and frontend with the same options Server: Cyrus-HTTP/3.0.9 Cyrus-SASL/2.1.26 OpenSSL/1.0.0 Nghttp2/1.35.0 Zlib/1.2.11 LibXML2.9.5 SQLite/3.24.0 LibiCal/3.0 ICU4C/59.1 Jansson/2.10 WWW-Authenticate: Basic realm="frontend.eurecom.fr" DAV: 1, 2, 3, access-control, extended-mkcol, resource-sharing DAV: calendar-access, calendar-auto-schedule DAV: calendar-query-extended, calendar-availability, calendar-managed-attachments DAV: calendarserver-sharing, inbox-availability DAV: addressbook Allow: OPTIONS, GET, HEAD, POST, PUT, PATCH, DELETE, TRACE Allow: PROPFIND, REPORT, COPY, MOVE, PROPPATCH, MKCOL, LOCK, UNLOCK, ACL Allow: MKCALENDAR Content-Length: 0 The question is: Is there specific configuration parameters to enable proxy http/https in murder configuration ? I can't find usefull informations in the documentation. I've seen the Interactive HTTP test program httptest, but can't find parameters to simulate calendar clients.
