Network security credential propagation enhancement coexistence considerations

The network security credential propagation enhancement introduces some specific considerations for coexistence with IMS 15.5.

If network security credentials are sent from a client application of IMS TM resource adapter, the credentials can be passed to IMS and audited in IMS log records only if IMS, IMS Connect, and IMS TM resource adapter are all Version 15 or later. If network security credentials are included in messages from IMS TM resource adapter Version 15 and IMS Connect is Version 14 or earlier, the messages are sent to IMS Connect without the network security credentials, even if the IMS system is Version 15 or later. If network security credentials are sent from IMS TM resource adapter Version 15 and the IMS system is V14 or earlier system, you must modify the HWSJAVA0 user message exit to remove the network security credentials from the security-data section of the OTMA message prefix.

If network security credentials are sent from a user-written client application that uses the HWSSMPL0 or the HWSSMPL1 user message exit, the credentials can be passed to IMS and audited in IMS log records only if IMS and IMS Connect are both Version 15 or later. If network security credentials are sent from an application that uses HWSSMPL0 or the HWSSMPL1 and IMS Connect is Version 14 or earlier, the IRM extensions that contain the network security credentials are ignored, even if the IMS system is Version 15 or later. If network security credentials are sent from an application that uses HWSSMPL0 or the HWSSMPL1 and the IMS system is Version 14 or earlier, the user message exit removes the security credentials from the OTMA message prefix.

If network security credentials are included in IMS callout messages to IMS TM resource adapter Version 14 or earlier, the credentials are removed from the callout messages.
