Quick question:

How would you configure AD to authenticate with a different Zimbra account name? For example: jason.hung@domain.com (Zimbra account) and jhung (Active Directory account). For now, we have been using internal authentication since we haven't figured out how to link the two. We don't want to use jhung@domain.com as the primary email; we want to use jason.hung@domain.com with jhung as the AD Login.

Can I bind LDAP to the email address listed in AD for the user? Is there a better way to keep the email address first.last@domain.com?
