I have an Active Directory Domain with Exchange Server 2003 running on server 2003. My Corporate HQ runs off a Linux LDAP system. The LDAP system contains several domains including the one assigned to my organization. Is there a way to get all the LDAP domains included in my global address list. Also, is it possible to sync user names and passwords with the LDAP accounts. I am currently getting a LDAP server built locally that will sync with the HQ LDAP server. Any suggestions?
