Calendar Address iCloud Lightning Sync

Right. Since you are using a HTTPS-URL the only thing you will see this way is the host you are connecting to.

The URL-path will be part of the HTTP-GET-Request, which will be encoded already.

What you need is a proxy that can act as a man-in-the-middle, so you can inspect the request being send:

Uhm, yes. I think this is the best moment to give up. Was a nice idea but maybe someone someday will provide an out-of-the-box-tool for Linux that does not extend my possibilities.😟

Thanks for your help Stephan.

My setup:

desktop computer:

Ubuntu 12.04 LTS

Thunderbird 17.0.5

Lightning 1.9.1

laptop computer:

MacBook Pro / OS 10.7.5

Using Stephan's instructions from 2012-02-02 post, I was able to create Lightning calendars on desktop computer from 8 calendars that had been sync'd to iCloud from laptop computer.

Created URLs for these calendars from looking through laptop directory path. Note that these URLs were of the form:

https://pXX-caldav.icloud.com:443/#myUniqueIDHere#/calendars/#calendar_name#/

where XX is a two-digit number, and #calendar_name# was either the name of my calendar, such as "home" (in 1 case), or a lengthy series of characters as described in iWolfgang's post of 2011-10-26.

For 6 of 8 calendars, Lightning had full read-write access -- changes made in Lightning on desktop computer propagated to iCal on laptop within seconds. For 2 of 8 calendars, attempted changes in Lighting triggered "server error 403." Not sure what the critical differences are between the calendars in this case, so, for now, these 2 calendars are read-only in Lightning.

Note that I tried Erusa's instructions, and they also work, however, all calendars were then read-only in Lightning since they were being shared "Public" from iCloud. Using the method descibed above, no particular sharing settings needed to be set for the calendars in iCloud.

Many thanks to all for your help and information.

If you have Firefox with the Firebug addon it is rather easy to figure out the right URL components. Just open the Web iCloud calendar and, for example, disable/enable a calendar. Then look at the content of the POST request.

SSL isn't an issue here as you are looking at the request in FF, not at the network level.

You will notice that the display name of the calendar and its id in the request can differ.

Hi,

I tried everything described in this thread and still didn't work until I modified the agent parameter as mentioned in this link:

After this it works like a charm!

oscarc23 thank you so much for posting this! My setup stopped working a few weeks ago and it was driving me crazy. This fixed it!

The solution for quick readers:

- In Thunderbird go to "Preferences -> Advanced -> Config Editor..."

- Search for "agent"

- Modify "calendar.useragent.extra" to "Lightning"

I had realized that it stopped working after the update to 1.9.1 but I had never suspected that Apple was to be blamed when Lightning stopped connecting to the caldav. What a poor decision of Apple's management!

I hope this solution spreads fast enough, so that users are not considering to give up using Lightning, as this seems to be what Apple wants. Instead I will now look into setting up my own caldav server as Apple clearly isn't a good partner to manage my calendar.

Thank you Stephan! Your solution works like magic!
