The Already Verified Indicator

CA XCOM Data Transport for z/OS supports a field called the “already verified indicator” in the function management header (FMH-5 or Attach Header). This bit is set if all of the following conditions are met:

• The user omits a password and does not override their password.
• The remote system is defined with ACCSEC=YES.
• The BIND specifies that ACCSEC is supported. The BIND must also specify that the FMH5 user ID “already verified” indicator will be allowed. This usually requires a configuration parameter on the IBM midrange system.
