- had to implement a workaround for Lightning, as it wrongly interprets principal-property-search for calendar-home-set in the principal-collection-set matching our *DAV root returning all principals, as all have a matching calendar-home-set, as NOT supporting CalDAV scheduling --> search only current user's principal, when Lightning searches for calendar-home-set - OPTIONS / return now calendar-auto-scheduling too, as Lightning only searches there, to check if server supports CalDAV scheduling - fixed outbox freebusy request to cope with no X-CALENDARSERVER-MASK-UID and a single attendee
