I am trying to get iCal and Thunderbid/lightning working together in my office. The problem I am having is events created in Thunderbird are not being automatically sent to other users/attendee calendars. Watching Calendar Server while creating an event within iCal, I can see the event get created, then get sent out to any attendees I have added. === Snip === 2008-07-28 13:51:18-0700 [-] [caldav-8008] [HTTPChannel, 42,10.41.41.2] PUT /calendars/__uids__/ 0000011ac1825abda7a58b05000a0029000b0015/calendar/F5C49F73- E3B6-4F18-8681-25BA19F4A197.ics HTTP/1.1 2008-07-28 13:51:19-0700 [-] [caldav-8008] [-] Writing to file /home/ eyespot/ical.eye-apl.base.2528-be.2.0-061308/CalendarServer-1.2/esdata/ calendars/__uids__/0000011ac1825abda7a58b05000a0029000b0015/calendar/ F5C49F73-E3B6-4F18-8681-25BA19F4A197.ics 2008-07-28 13:51:21-0700 [-] [caldav-8008] [HTTPChannel, 43,10.41.41.2] PUT /calendars/__uids__/ 0000011ac1825abda7a58b05000a0029000b0015/calendar/F5C49F73- E3B6-4F18-8681-25BA19F4A197.ics HTTP/1.1 2008-07-28 13:51:21-0700 [-] [caldav-8008] [-] Writing to file /home/ eyespot/ical.eye-apl.base.2528-be.2.0-061308/CalendarServer-1.2/esdata/ calendars/__uids__/0000011ac1825abda7a58b05000a0029000b0015/calendar/ F5C49F73-E3B6-4F18-8681-25BA19F4A197.ics 2008-07-28 13:51:24-0700 [-] [caldav-8008] [HTTPChannel, 44,10.41.41.2] POST /calendars/__uids__/ 0000011ac1825abda7a58b05000a0029000b0015/outbox/ HTTP/1.1 2008-07-28 13:51:27-0700 [-] [caldav-8008] [HTTPChannel, 45,10.41.41.2] POST /calendars/__uids__/ 0000011ac1825abda7a58b05000a0029000b0015/outbox/ HTTP/1.1 2008-07-28 13:51:28-0700 [-] [caldav-8008] [-] Writing to file /home/ eyespot/ical.eye-apl.base.2528-be.2.0-061308/CalendarServer-1.2/esdata/ calendars/__uids__/0000011ac1825f6db139129f000a0029000b0015/inbox/ c46caa18ce1fb728e962b24c94ac74a2.ics 2008-07-28 13:51:28-0700 [-] [caldav-8008] [HTTPChannel, 46,10.41.41.2] PUT /calendars/__uids__/ 0000011ac1825abda7a58b05000a0029000b0015/calendar/F5C49F73- E3B6-4F18-8681-25BA19F4A197.ics HTTP/1.1 2008-07-28 13:51:28-0700 [-] [caldav-8008] [-] Writing to file /home/ eyespot/ical.eye-apl.base.2528-be.2.0-061308/CalendarServer-1.2/esdata/ calendars/__uids__/0000011ac1825abda7a58b05000a0029000b0015/calendar/ F5C49F73-E3B6-4F18-8681-25BA19F4A197.ics 2008-07-28 13:51:34-0700 [-] [caldav-8008] [HTTPChannel, 47,10.41.41.2] PROPFIND /calendars/__uids__/ 0000011ac1825abda7a58b05000a0029000b0015/ HTTP/1.1 2008-07-28 13:51:34-0700 [-] [caldav-8008] [HTTPChannel, 48,10.41.41.2] PROPFIND /calendars/__uids__/ 0000011ac1825abda7a58b05000a0029000b0015/calendar/ HTTP/1.1 === Snip === When doing the same in Thunderbird, the event is never copied to the other attendees calendars. === Snip === 2008-07-28 13:39:43-0700 [-] [caldav-8008] [HTTPChannel, 31,10.41.41.2] PUT /calendars/users/bevans/calendar/8573c796-4c9b-4bec- bbf8-07e670170caa.ics HTTP/1.1 2008-07-28 13:39:43-0700 [-] [caldav-8008] [-] Writing to file /home/ eyespot/ical.eye-apl.base.2528-be.2.0-061308/CalendarServer-1.2/esdata/ calendars/__uids__/0000011ac1825abda7a58b05000a0029000b0015/calendar/ 8573c796-4c9b-4bec-bbf8-07e670170caa.ics 2008-07-28 13:39:43-0700 [-] [caldav-8008] [HTTPChannel, 31,10.41.41.2] REPORT /calendars/users/bevans/calendar/ HTTP/1.1 2008-07-28 13:39:43-0700 [-] [caldav-8008] [-] Attribute collation is unexpected in {urn:ietf:params:xml:ns:caldav}text-match element === Snip === I have tried this using the 1.2 Calendar server branch, as well as the latest trunk (as of 7/28/08) I am using Thunderbird 2.0.0.16 with lightning 0.8 I have also tried the latest Sunbird (including nightly build) Any ideas on what may be wrong? Is this due to the attribute collation error printed above & mentioned here http://archive.netbsd.se/?ml=calendarserver-dev&a=2008-04&t=6921251 ? I am using custom LDAP directory service modules (http://trac.calendarserver.org/ticket/260 ). Could the problem be something wrong with the LDAP directory modules? If so, any hints on what might be missing would be great. -Brandon
