PKI Services uses the IBM® HTTP Server for the following functions:

• The PKI Services web application, if you implement it using REXX CGI scripts.
• OCSP support
• SCEP support
• CMP support

You need to perform the tasks in this topic only if you are configuring PKI Services for the first time and use one or more of these functions. If you don’t use any of these functions, you can skip the tasks in this topic.
