2.2 Configure a Client Authentication Level.
DCAS and RACF support several levels of authentication.
Authenticating the DCAS server:
The DCAS client always authenticates the DCAS server. This requires that the DCAS client sent the client’s z/OS application ID and user ID to the DCAS server.
Authenticating the DCAS client:
The DCAS client uses a key pair and certificate to authenticate to the DCAS server. Different authentication level (levels of strictness) can be configured for the DCAS client’s authentication to the DCAS server.
