About this task

To use basic authentication to authenticate your CICS application you must
  • Use the CICS XWBAUTH user exit to specify credentials (user ID and password) to be sent to IBM z/OS Connect.
  • Customize the supplied URIMAP BAQURIMP specifying
    • USAGE(CLIENT) because CICS is the HTTP client.
    • AUTHENTICATE(BASIC) to indicate that the user ID and password credentials are to be provided by the XWBAUTH global user exit.

Note that your CICS application should not provide credentials in an EXEC CICS WEB SEND or WEB CONVERSE command as this is not supported by IBM z/OS Connect and will be ignored.
