All Implemented Interfaces:

public class ConfigurableSpnegoLoginService
extends ContainerLifeCycle
implements LoginService

A configurable (as opposed to using system properties) SPNEGO LoginService.

At startup, this LoginService will login via JAAS the service principal, composed of the service name and the host name, for example HTTP/wonder.com, using a keyTab file as the service principal credentials.

Upon receiving an HTTP request, the server tries to authenticate the client calling login(String, Object, ServletRequest) where the GSS APIs are used to verify client tokens and (perhaps after a few round-trips) a GSSContext is established.
