Method Details- 
doAuthenticateAuthenticate the user making this request, based on the fact that no login-confighas been defined for the container.This implementation means "login the user even though there is no self-contained way to establish a security Principal for that user". This method is called by the AuthenticatorBase super class to establish a Principal for the user BEFORE the container security constraints are examined, i.e. it is not yet known whether the user will eventually be permitted to access the requested resource. Therefore, it is necessary to always return trueto indicate the user has not failed authentication.There are two cases: - without SingleSignon: a Session instance does not yet exist and there is no auth-methodto authenticate the user, so leave Request's Principal as null. Note: AuthenticatorBase will later examine the security constraints to determine whether the resource is accessible by a user without a security Principal and Role (i.e. unauthenticated).
- with SingleSignon: if the user has already authenticated via another container (using its own login configuration), then associate this Session with the SSOEntry so it inherits the already-established security Principal and associated Roles. Note: This particular session will become a full member of the SingleSignOnEntry Session collection and so will potentially keep the SSOE "alive", even if all the other properly authenticated Sessions expire first... until it expires too.
