java.lang.Objectorg.springframework.security.authentication.jaas.SecurityContextLoginModule
public class SecurityContextLoginModule
An implementation of LoginModule
that uses a Spring Security SecurityContext
to provide authentication.
This LoginModule provides opposite functionality to the JaasAuthenticationProvider
API, and should not
really be used in conjunction with it.
The JaasAuthenticationProvider
allows Spring Security to authenticate against Jaas.
The SecurityContextLoginModule allows a Jaas based application to authenticate against Spring Security.
If there is no Authentication in the SecurityContextHolder
the login() method will throw a LoginException
by default. This functionality can be changed with the ignoreMissingAuthentication option by setting it
to "true". Setting ignoreMissingAuthentication=true will tell the SecurityContextLoginModule to simply return false
and be ignored if the authentication is null.

LoginModule
. Ignores the callback handler, since the code establishing the
LoginContext
likely won't provide one that understands Spring Security. Also ignores the
sharedState
and options
parameters, since none are recognized.
