One way sync?
I have a new Network Edition install and thus far I am very impressed. I have multiple users with Macs all using the iSync connector, some with multiple accounts configured. I have a requirement to set some of the accounts configured in the sync connector to be one way, meaning either they sync changes to the server but not back to the client or the opposite. I do not want users changing their address book, adding contacts, etc. to pollute the secondary accounts, I just want changes to those to be pushed down to the users but not up to the server.
Is this possible?
Sounds like you should be using sharing between accounts instead of having people access multiple accounts from the same iCal.
If you mount a shared calendar using the web client, it will appear in iCal via CalDAV. Share it read only and that should solve at least one of your problems.
