[CalendarServer-users] Read only access to CardDAV

Thanks dre, I realised after asking that it had moved to a postgres backed datastore.

Although, I guess we could have 2 cardDAV servers running, one in read only and the other in read-write, but both on the same DB backend? In the read only server, authentication would be valid for all listed in the ou=people branch of the directory, but the read-write server would only allow connection from specific roles...just a thought, or is this completely outrageous?

I'll also be sure to check out gaya's branch to see what direction is being taken there, perhaps I can help out with that.

I would like to have one collection of contacts which has an admin user with read/write access but to also have a subordinate user who can connect to this collection with read only access. I don't particularly need to be able to provide a separate contacts collection for the subordinate user.

Symlinks probably won't help you here; the Calendar Server backend is a postgres database. It used to be a filesystem, but that was a long time ago...

Unfortunately I don't think there's currently any support in the server for what you're asking for. There is a 'read only server' switch, but it's global for the entire service. There is some CardDAV sharing stuff in development, but it's not release-quality yet. Here's the branch if you're curious what is being done:
