Connection between the z/OS Platform Receiver and Event Journal Services uses Secure Sockets Layer (SSL). SSL connections are authenticated through the use of certificates.
The certificates used by the Identity Manager Fan-Out driver are minted by the Certificate Services component of the core driver. When you install and configure Platform Services, you obtain a certificate.
To obtain a new certificate, run the Platform Receiver with the -s command line parameter.
Platform certificates are stored in the HFS asam/data/platformservices/certs directory. Ensure that access to the certs directory is limited to the appropriate users.
