IMS security enhancements

IMS 15.3 introduces security enhancements.

RACF PassTicket support for commands from IMS Connect to IMS OM
In IMS 15.3, IMS Connect (ICON) clients can use RACF® PassTicket authentication to issue commands to IMS Operations Manager (OM) for more secured connections.
Displaying RACF sign-on messages
In IMS 15.3, after APAR PI85328 (PTFs UI57463 and UI57462) is installed, you can configure IMS to pass RACF sign-on messages to the Greeting Message exit routine (DFSGMSG0) when sign-on is successful. You can code the DFSGMSG0 user exit routine to display or process the RACF messages to improve security and password management.
Generic return code enhancement for RACF verifications
In IMS 15.3, if RACF is used to provide sign-on verification for VTAM® terminals or IMS Connect clients and the user ID or password provided at sign-on is invalid, you can enable a generic return code or message to be returned instead of the actual RACF or IMS return code.
