Question

Apple "iCal" server calendaring issue

Asked by: wbokhary

Our environment consists of a DNS server separate from our apple's server, in other words, apples server is solely used only for calendaring. Even the open directory is used primarily  for calendaring.
This server does not handle, mail, dns, or any other services.

Within open directory on apple's server we have our users.

When we setup our users for calendering some users can see the "free/busy" schedules, others cannot. We use thunderbird with lightning plugin for caldav support for users with no MACs.

Here are the errors we are seeing in the logs: for people who can't see free/busy.

2009-08-05 12:09:50-0500 [-] [caldav-8009]  [-] "No principal for calendar user address: 'mailto:user@domain.com"
2009-08-05 12:09:50-0500 [-] [caldav-8009]  [-] 'No schedulable principal for calendar user address: mailto:user@domain.com
2009-08-05 12:09:50-0500 [-] [caldav-8009]  [-] 'Error during POST for mailto:user@domain.com: None'
2009-08-05 12:10:49-0500 [-] [caldav-8009]  [AMP,client] POST /calendars/__uids__/E0BAF924-0610-47F9-A3DE-DF0D8E4A54F6/outbox/ HTTP/1.1
2009-08-05 12:12:10-0500 [-] [caldav-8009]  [AMP,client] POST /calendars/__uids__/E0BAF924-0610-47F9-A3DE-DF0D8E4A54F6/outbox/ HTTP/1.1
2009-08-05 12:12:10-0500 [-] [caldav-8009]  [-] "No principal for calendar user address: 'mailto:user@domain.com"
2009-08-05 12:12:10-0500 [-] [caldav-8009]  [-] 'No schedulable principal for calendar user address: mailto:user@domain.com
2009-08-05 12:12:10-0500 [-] [caldav-8009]  [-] 'Error during POST for mailto:user@domain.com: None'

What do these errors signify, and why are we getting these for some and not the other users. Deleting and recreating the users in open directory didn't solve the problem, the permissions of these users is identical to the users which can see "free/busy"

What do these error logs signify and how to rectify the problem?

Thanks

iCal server is the biggest nightmare ever created. This happens when you delete users from Open Directory who had Calendaring enabled, or maybe even any user. You have to re-create the deleted users with the UID you see above "E0BAF924-0610-47F9-A3DE-DF0D8E4A54F6". It may work if you just create any user with that UID but I've never tried it that way.

You can change the UID for the user within the advanced settings in the Workgroup Manager.

Thank you so much for that, I don't know if you have apple's server infront of you and if you can tell me how to create a user with this id:E0BAF924-0610-47F9-A3DE-DF0D8E4A54F6 will t his fix the problem?
How can I change it within workgroup manager, please if you have some time can you specify?
Thanks a bunch.

Launch Workgroup Manager > click on the Workgroup Manager menu and go to Preferences > check "Show "All Records" tab and inspector" > create the new user > select the new user > click on the "inspector" tab to the right > copy and paste that UID above into the "Generated UID" and "dsAttrTypeNative:apple-generateuid" fields > save

That should be it...after you get this ironed out. It's easier to just disable users if you have an unlimited license.

 

by: wbokharyPosted on 2009-08-05 at 11:42:48ID: 25026670

renazonse, thanks for the procedures.
Unfortunately, I tried to recreate the user with the exact steps, using the GUID as stated, however, still no avail.
It still gives the exact same error as before (above) even though the GUID is now changed to match the error above.
Any ideas, thanks.

 

by: renazonsePosted on 2009-08-05 at 11:44:53ID: 25026695

you may need to restart the calendaring services or possibly reboot the server.

Actually looks like there's a newer fix out there. You may want to delete that user you just created and give this a whirl:

by: wbokharyPosted on 2009-08-05 at 15:00:50ID: 25028495

Will apply this, let's see what happens.
So you do think tha tthe problem revolves around GUID's?
Another thing I must mentioin here is that we imported all our user accounts from our mail servers directory. Do you think that could have anything to do with it?
thanks for your help so far.

 

by: renazonsePosted on 2009-08-06 at 05:46:29ID: 25032584

Not sure if it has to do with the import but it definitely is related to the UID's. I've been through this problem over and over again.

For several users on our server, free/busy info cannot be viewed. When a user goes to invite attendees to an event, and types in their email address, the following shows up in the log:

2009-08-06 16:06:29-0500 [-] caldav-8009 AMP,client POST /calendars/__uids__/E0BAF924-0610-47F9-A3DE-DF0D8E4A54F6/outbox/ HTTP/1.1
2009-08-06 16:06:29-0500 [-] caldav-8009 [-] "No principal for calendar user address: 'mailto:user@domain.com'"
2009-08-06 16:06:29-0500 [-] caldav-8009 [-] 'No schedulable principal for calendar user address: mailto:user@domain.com'
2009-08-06 16:06:29-0500 [-] caldav-8009 [-] 'Error during POST for mailto:user@domain.com: None'

When I run sudo kadmin.local -q list_principals from the terminal I show the person's username listed in the results, however the output of this command is in the format user@icalserver.hostname (in other words, the internal DNS hostname for the server), rather than user@domain.com (the email address of the user).

Can anyone explain what I may be doing wrong here? I'm running OS X Server 10.5.7 with OpenDirectory and iCal services, and using Thunderbird 3.0b2 with Lightning 1.0pre plugin. I was able to see freebusy information until just recently, so I know it worked in the past, and nothing has changed on the client end, so something must have changed on the server.

 

by: wbokharyPosted on 2009-08-13 at 09:32:21ID: 25090224

What fixed the problem is that in the open directory there is a field which populates the email address of the users. That was not filled for most of the users. Once that was populated correctly the problem disappeared.
