Customer was also looking for our help in performance tuning / customization of the application running on iPlanet Server.

Approach & Solution

Criteria of selections

Our approach to the problem has considered the points including Security, Speed & Scalability of the application running on the iPlanet platform.

The recommended servers are:

• iPlanet web server 4.1 for the user interfaces (inbuilt support for java and also for LDAP connectivity).
• Netscape directory server 4.0 for user directory, user authentication (having LDAP support and it could directly communicate with iPlanet servers through java. Fast authentication plus access security that can be defined)
  Some of the key points kept in mind while server was configured:
• The Directory Server needs to be installed on NTFS file system for security.
• The machine name and domain names should not be hard coded in the program source of the LDAP client, which connects to the directory.
• JAVA core and J2EE were used for the reasons of robustness, platform independent nature, and usable built in API’s to program LDAP clients
• The user interfaces were controlled using JSP’s and connectivity using Servlets.

Model used for designing the system was Top-Down model.

Total effort to design and deliver the system was 5 man-months.

While we delivered the solution well within the schedule, the customer was very happy with the user-friendly GUI designs.
