I performed some testing and it looks like after upgrading to 2014 the users come in as GroupWise users associated to eDirectory with GroupWise authentication.

1. From testing it looks like I can add a secondary AD Directory without causing a disruption to the current configuration. It looks like GroupWise will sync with both directories fine and not cause any changes until I actually associate a user to AD. Is this correct?

2. LDAP authentication appears to be a all or nothing per Post Office. Is this correct?

3. Why would I want to push the email address back into LDAP?
