The name of the authentication system that is configured for the domain specified by the
DOMAIN-NAME attribute. This authentication system authenticates or validates the user identity represented by the client-principal object.
The configured authentication system determines the operation type (user authentication, single sign-on (SSO), or both) and mechanism (OpenEdge-defined or application-defined) that is available to validate and set a given user identity. For more information on authentication systems, see OpenEdge Getting Started: Identity Management.
If not already assigned, during any OpenEdge-performed user authentication operation, OpenEdge assigns the value of this attribute from the domain configuration used to authenticate the asserted identity before sealing the client-principal object.
Once the client-principal object is sealed, this attribute is read-only, and attempting to write to it raises a run-time error.
