Error in adding attendee to meeting

[Corey Scobie]

I have had CalendarServer installed and running for some time on OS X 10.5. Recently I have been getting errors as below whenever an event is created or edited to add an attendee.

In a Terminal.app window please do:

xattr -l
/Library/CalendarServer/twistedcaldav/test/data/calendars/__uids__/ks/co/kscobie/calendar

and post the result back to the list.

Strangely, the directory doesn't exist for this user (does for my other user).

macmini:/ cscobie$ ls /Library/CalendarServer/twistedcaldav/test/data/calendars/__uids__/ks/co/kscobie/calendar

ls: /Library/CalendarServer/twistedcaldav/test/data/calendars/__uids__/ks/co/kscobie/calendar: No such file or directory

Delete the user and recreate? The user can create and update events just fine.

Hey Corey,

could it be possible that you have installed the Calendar Server to another directory (your home directory for example)?

OK, so your client tried to access a "calendar" directory in that location
and as you can see it does not exist. What client are you using? If it is
iCal, try removing then re-adding the account for that server.

Removing and re-adding on the client (yes, it is iCal) or on the Server?

For all those that may be interested it took a little trial and error to figure this out but here is the synopsis.

iCal (I assume it is iCal) expects a default calendar with the uid "calendar". One that can be found at /calendars/__uids__/username/calendar as a Caldav URL. Apparently this is the default collection UID used in collaborative scheduling (inviting another user to a meeting). When you set up a new iCal client for the first time, this calendar is automatically created on the caldav server. I was (I guess) dissatisfied with this calendar name, and instead of renaming the default calendar to something else I created a new calendar and then deleted "calendar" - thus forcing the server to remove the "calendar" uid (directory) under my user. This must have been different than my original provisioning process for these accounts and therefore broke one account.

To resolve this problem it was not enough to just remove and re-add the account in iCal because the existing account data on caldav would just repopulate the iCal client. Instead, I followed this procedure.

1. Export each caldav Calendar's contents to an ICS file.

2. Remove the caldav account from my iCal configuration.

3. Stop the caldav server.

4. Remove the data directory (under twistedcaldav/test/data/calendars/__uids__/) for the user in question.

5. Restart the caldav server.

6. Re-create the caldav account in iCal.

7. Rename the default "calendar" calendar in iCal to the name of my default calendar for this user (i.e. Personal Events).

8. Import the contents of the ICS file for this calendar back into the recreated calendar.

9. Recreate calendars and re-import contents for any additional calendars.

I am sure there must be an easier way to do this, but this process definitely works. I have to admit, I do not have a very clear understanding of the relationship between the data stored in these directories, any meta data on the server, any meta data on the iCal client, and who is responsible for the actual file/folder structure on the caldav server. I suspect there is some way to force the iCal client to look for something other than the "calendar" uid for meeting requests, but I couldn't find anything via a thorough Google search.

 Hope this helps others.

Regards,

Corey

The process you described should not be needed. iCal does not require that
a calendar called "calendar" be present. It is capable of scanning the
parent directory looking for all "collections" that have been tagged as
calendars.

There is a lot of talent in this mailing list and a lot of knowledge  
contained within its postings.  However, the information can be  
difficult to find and certainly, questions get repeated.  A wiki has  
been set up to help make information regarding installing and  
configuring DCS a little easier to find.

http://dcswiki.org

There is a solid set of basic information already there, but much more  
to do (e.g., nothing on troubleshooting yet at all).  It would great  
if some the gurus around here would lend a hand.
