This Shared Address Book is based on a well established directory protocol called LDAP, or Lightweight Directory Access Protocol. It is an open standard and used by both Microsoft and Novell as part of their Directory systems. What we have done is to create a web interface that allows you to store all your addresses in a single place and access them from many different applications. Not only can most email applications use LDAP to look up addresses, but some phone handsets and a number of multi-function fax-printers. We have also added an export to Palm based PDA's via the HotSync file-link facility. - This feature is part of the Base Install Module and was added to all our systems on 31st March 2006.
