User Authentication Credential Segment
Definition: This optional segment provides user authentication credentials, a Kerberos Service Ticket or SAML assertion, to be used by the receiving system to obtain user identification data. Refer to HL7 Table 0615 - User Authentication Credential Type Code. It is to be used in when the receiving application system requires the sending system to provide end-user identification for accountability or access control in interactive applications. Since user authentication implementations often limit the time period for validity of the session authentication credentials, this segment is not intended for use in non-interactive applications.
It is possible that various user authentication credential standards' data may be communicated. Kerberos and SAML are two such standards. A user authentication credential is an encapsulated data (ED type) element, as defined by standards, with no HL7-relevant structure.
