How to Use Already Verified Authentication
You can set the Use Already Verified or Persistent Verification authentication option on the remote environment (RE) Security property page in Transaction Integrator (TI) Manager.
To view or modify the Security properties for an RE
Start TI Manager.
Right-click the RE, and then click Properties.
Click the Security tab, and then select the Set security on check box.
When you select the Use Already Verified or Persistent Verification authentication check box, only a user ID is sent to the mainframe; that is, no password is sent, provided the mainframe partner allows it. The mainframe relies on the assumption that this user ID has already been authenticated and does not require a password. The SNA mode on the mainframe must specify this type of authentication. For CICS applications, the mode setting is determined by the ATTACHSEC=IDENTIFY parameter of the Sessions definition used for the connection.
