Developing a user mapping plug-in (C programming language)

The plug-in that you develop must connect to the external repository, retrieve user mappings, and decrypt remote passwords. The repository that you use determines how you code the plug-in.

About this task

Important: Be aware that as you develop and use the plug-in, you send sensitive user IDs and passwords between multiple sources. To protect this information, restrict access to the plug-in source code, and configure the Db2® audit facility to capture a VALIDATE record in the diagnostic log file each time that the federated server uses the plug-in. The diagnostic log file is useful not only for tracking usage but also for troubleshooting any problems that occur.
