Joseph Scott has posted instructions on how to use the information in an Active Directory in Windows Server 2003 as a back-end address book for Mail.app and Thunderbird, using its LDAP facility.

He provides step-by-step instructions and some suggested values for the various required fields.

He also offers a tip for anonymous access in case you are unhappy about entering your password to get access to the LDAP user info.

Normally I try to test things before posting them. I couldn’t test this. I have no access to a Windows Server 2004 setup and, God willing, never will.
