/**
|
|
* Handle principal-property-search report
|
|
*
|
|
* Current implementation runs a full infinity propfind and filters out not matching resources.
|
|
*
|
|
* Eg. from Lightning on the principal collection /principals/:
|
|
* <D:principal-property-search xmlns:D="DAV:" xmlns:C="urn:ietf:params:xml:ns:caldav">
|
|
* <D:property-search>
|
|
* <D:prop>
|
|
* <C:calendar-home-set/>
|
|
* </D:prop>
|
|
* <D:match>/egroupware/groupdav.php</D:match>
|
|
* </D:property-search>
|
|
* <D:prop>
|
|
* <C:calendar-home-set/>
|
|
* <C:calendar-user-address-set/>
|
|
* <C:schedule-inbox-URL/>
|
|
* <C:schedule-outbox-URL/>
|
|
* </D:prop>
|
|
* </D:principal-property-search>
|
|
*
|
|
* Hack for Lightning: it requests calendar-home-set matching our root (/egroupware/groupdav.php),
|
|
* but interprets returning all principals (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
|
|
*
|
|
* Example from iOS iCal autocompleting invitees using calendarserver-principal-property-search WebDAV extension
|
|
* <x0:principal-property-search xmlns:x2="urn:ietf:params:xml:ns:caldav" xmlns:x1="http://calendarserver.org/ns/" xmlns:x0="DAV:" test="anyof">
