You can use RACF to check whether the inbound request is authorized to access the local LU. However, if you are using the Adapter, it sends only the password, not the user ID. You can use the Gateway-Library function TDGETUSR to retrieve the user ID from the client login packet. For details on TDGETUSR, see the appropriate Mainframe Connect Server Option Programmers Reference. PL/1 and COBOL versions of this guide are available.
For further details, refer to the appropriate IBM documentation.
