This depends on your default settings.

In our case everyone has always "DateAndTime" privileges.
This is set in order to use invites with free/busy information.
Your search will give you all users (approx. 15000 in our case) and everyone with a valid calendar to subscribe to ;-)

So in our case not very useful.

@Christian
This is true only if everyone's calendar is set to be Shared with everyone else at the Company by default. Surely that is not the case?

Or maybe I'm mis-reading - the OP I think is asking to see only those calendars that have explicitly been shared with him...

I am asking for the list returned to not contain useless entries.

My point is that if the search results include a node for bob@example.com, then expanding that node had better show me at least one calendar which I have permission to view.

Currently, I can expand a node and be told "no possible subscription". I don't want to see a node for such users at all, as it is not useful to me.

@tanstaafl
In order to have free/busy information when inviting other people, you need "DateAndTime" privileges on their calendars.
Because of this we have these set per default.

Ah... so, then, Calendars with only these perms should be excluded from the results when intentionally looking for subscribable calendars/address books?

Sounds like that's the answer.

@dtn

Cool, then I suggest changing the Bug Summary to reflect this...

I cannot see any way for me to edit the Bug Summary.

Well, that sux...

Next best then I guess it so open a new one, and delete-dupe this one...

You need some additional privileges in the bugtracker to do so.
Just changed the subject ;-)
