Hi, i write this mail again because no one answered to the first one. i use calendarserver 2.x @ the latest debian testing with a local ldap server. everythings fine but i want to use locations (e.g. rooms). As i type a location (apple ical) a exclamation mark appears ... so he cant resolve the location. In my ldap there are two ou's called locations and resouces but which arguments are needed? I found the "rooms" attribute but that does not work for me, it seems that the calendar server is searching for an email-address (i use room only with cn=room 008b)? I know this behavior from exchange - a room with a mailaddress, so the room can "answer" that he's already booked. Can anybody tell me which attributes are needed for locations or is something else wrong? Hope this time i get some help :-) Simon
