With the basic authentcation (BasicAuth) mechanism, the client generates a security token, based on user ID and password, and it imbeds the token in the SOAP message. The server extracts the token and uses a Java Authentication and Authorization Service (JAAS) login module to validate the token. For an overview of the basic authentication mechanism, see Basic authentication.
