Actually, I personally wouldn't worry about write throughput on the LDAP master all that much. What concerns me more, is the absolute mess email clients have made of the concept of LDAP based addressbooks. They almost all want their own schema ideas in place as to how the data should be stored, which makes it virtually impossible to store the data in a way where all email clients are happy and/or know what to do with the data they get back.
