We're in the process of migrating several thousand users from MS Exchange. Since I can't find a way to create a contact in the GAL for Zimbra, we've created a shared mailbox that contains the Contacts from the Global Address List in the several domains we're migrating from. I've had a developer automate this so that it reads LDAP and pushes the contacts out to the Contacts folder automatically. This is working fine.
We have a problem though, because some of our many road warriors use the web interface, and I can't find a way to allow them to read the shared mailbox contacts.. Is there a way? I hope so.
