Delegate-user-identity is a one-byte EBCDIC field that indicates whether the new connection's user identity is made available to applications on Teradata Database so that they may act on behalf of the user. The identity is an internal representation of the identity, not simply a cleartext password.
Use of this option requires specification of a Mechanism-name.
Delegate-user-identity exists only when DBCHINI had been called for a DBCAREA with Total-length set to at least 640 (that is, the returned DBCAREA Level value is at least 1). For a smaller DBCAREA, Delegate-user-identity is ignored.
Logon mechanisms are currently not supported for a mainframe-connected system.
