First request ignored

Hey everybody, I've setup calendarserver 3.2 on my debian wheezy using the filesystem as storage. Every time I add a new appointment to my calendar in iCal and give it a Name, after the next sync with the Server it reverts to the old name ("new Event"). It seems like just the second change will be actually changed on the server. Same Behavior when I change the time. And I also need to delete every appointment two times. I attached the access.log file, there you can clearly see that the server gets a GET request right after deletion and I need to delete the appointment a second time. Hope you can help me out Ulrich Fourier

DCS Production Deployment

Hi, Thank you very much for CalendarServer I have few questions: * I used CalendarServer-5.2.2 during development phase. * Now I want to use it for some real (users) use cases. * Right now, I do not have any scaling issues. * I run it on Ubuntu EC2 instance. My question is: * Has CalendarSever-5.2.2 been used in PROD deployments? * Since I don't have scaling issues, is it ok to use XMLDirectoryService for like 1000 accounts? Any tip would be useful for PROD deployments. Even for 1000 users, we would like it not to go down at all. Best Regards, Gaurav Jain

How can Attendee know that Organizer does not exist in system anymore
by Gaurav Jain 17 Feb '15

Please pardon my ignorance. I have a question of CalDav Protocol * I have an organizer, 'User1' * I have an attendee, 'User2' * User1 organized an event with User2 * Now User1 got removed from the system. Maybe he did not do any actions on the event he created. His account got removed. How can User2 know that User1 no longer exist and the event in his calendar is invalid??? Regards, Gaurav Jain

Connection aborted - took too long to close

* CalendarServer 5.3 * Clients: Calendar.app on MacOSX and iOS. All of a sudden, I am getting a lot of [twext.web2.channel.http#error] Connection aborted - took too long to close errors in my logs -- essentially every time the client tried to manually refresh the calendars. To be more precise, only certain clients (or delegates) seem to be affected -- those with rather large calendars. I wonder if some internal limit on the server side has been exceeded, causing the transaction to fail. Any pointers for debugging this would be appreciated.

Groups with members, but no members with group memberships!
by Tim McBride 04 Feb '15

Hi Guys, I've been using 6.0 and have been having some trouble getting groups working properly. Namely, I have groups that have members, but when I go to an individual user, that user will have nothing listed under "Group Memberships". I am using OpenLDAP and a groupOfUniqueNames object class to store my groups. The issue, as I understand it, is that calendarserver is querying the groups for the principal UID, and not the distinguished name, of the user.This will not work as the 'uniqueMember' attribute of 'groupofUniqueNames' is a fully qualified DN, and not a uid. Anyone have experience with 6.x and OpenLDAP? Many thanks in advance.

Kerberos and install on OmniOS (illumos)
by Olaf Marzocchi 01 Feb '15

Dear all, I am preparing a server based on OmniOS (kernel illumos), let’s say the successor of OpenIndiana (OpenSolaris) and I would like to offer CalDAV/CardDAV to the users. I chose calendarserver because the users use iOS, OS X, Android. I run “python setup.py” and everything runs well (I just needed to put the GNU tar in the path before the one provided by OmniOS/illumos) until PyKerberos. ------ ~/CalendarServer/CalendarServer-5.2 $ ./run -s Using built libevent.
