The following checklist summarizes the steps you should take when directory-enabling existing applications:
Identify one or more needs that can be met by integration of an existing application with an LDAP directory service.
Choose the best LDAP development tool for the task at hand.
Choose an approach to LDAP integration that allows you to meet your goals and satisfy the application's users.
Design your LDAP integration so that the resulting application coexists well with other directory-enabled applications and the directory service itself.
Document how the application will be integrated with the directory service, and share that information with the people who maintain the directory service.
Consider performance and scalability during LDAP integration design and implementation.
Plan for the transition from the older version of the application to the new LDAP directory-enabled version.
