I have installed owcnloud 9.1.2. Activated calendar app. Configure ldap authentication. Logins are OK. While sharing files i can search users through ldap when i write first three letters i get the results. But when i want to share an individual calendar with a user in ldap i cannot see any user name in the search box if i write letters in the textbox of the calendar sharing. I look at the server logs.
"app":"OCP\Share","message":"Sharing backend for principals not found","level":3,"time":"2017-03-14T08:36:32+00:00","method":"GET","url":"\/ocs\/v1.php\/apps\/files_sharing\/api\/v1\/sharees?format=json&search=m&perPage=200&itemType=principals","user":"13456et6e-4322-1031-96a8-95d08b905a28"}
On the other hand while adding an event to a calendar i can search and add attendees.
