public @interface CustomFormAuthenticationMechanismDefinition

Annotation used to define a container authentication mechanism that implements authentication resembling Servlet FORM authentication (Servlet spec 13.6.3).

Instead of posting back to a predefined action to continue the authentication dialog (Servlet spec 13.6.3 step 3), this variant depends on the application calling SecurityContext.authenticate(javax.servlet.http.HttpServletRequest, javax.servlet.http.HttpServletResponse, javax.security.enterprise.authentication.mechanism.http.AuthenticationParameters)
