If I use Outlook Express I can access the GAL using LDAP. I am also able to pull some search info via the LDP.exe utility. For the life of me, I have been unable to get the OSX address book to use LDAP to pull info from our Exchange 2000 Server. I have tried so many attempts I am having a hard time trying to figure out what else is possible. If anyone has any suggestions of how I can get the proper settings that the OSX address book needs for LDAP to work or what might be holding this process up, I would love to hear them.
