Define the conflicting certificates have same public key within RACF database

RACF database should have certificates with same public key to be defined. As long as certificates have different serial number, they should be consider as different certificates. 

Since Digicert has created two intermediate CA which have different serial number but same public key, it is necessary to have this function available. Considering Digicert is a world wide used certificate authority, more users may get impact in the future.  Clients may fail the SSL connection when it is pinning a specific Intermediate certificate, which is a practice we have seen many times.

    The problem was caused by the client side which pinned an intermediate CA certificate that has been renewed. This is a common problem with certificate pinning. The industry is moving away from certificate pinning.

    The server side can avoid the problem by just putting the server certificate in the key ring or the client side can remove the old intermediate CA certificate from the client key ring. If neither way is possible at the moment, a bypass can be done. Both the new and old intermediate CA certificates can be installed in RACF, but only one can be installed under CERTAUTH, while the other one is added under a different ID. Depends on the target client, the server key ring can pick which intermediate CA to be connected to, with the connect usage specified. Don?t put both in the same keyring though since the one get picked may not be the desired one for the target client. This is considered a temporary set up, the old intermediate CA should be removed from the server and client side eventually.
