Package org.springframework.security.authentication.jaas

Class SecurityContextLoginModule

  • All Implemented Interfaces:
    javax.security.auth.spi.LoginModule
    public class SecurityContextLoginModule
extends java.lang.Object
implements javax.security.auth.spi.LoginModule
    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.

      • abort

        public boolean abort()
        Abort the authentication process by forgetting the Spring Security Authentication.
        Specified by:
        abort in interface javax.security.auth.spi.LoginModule
        Returns:
        true if this method succeeded, or false if this LoginModule should be ignored.
        Throws:
        javax.security.auth.login.LoginException - if the abort fails

      • commit

        public boolean commit()
        Authenticate the Subject (phase two) by adding the Spring Security Authentication to the Subject's principals.
        Specified by:
        commit in interface javax.security.auth.spi.LoginModule
        Returns:
        true if this method succeeded, or false if this LoginModule should be ignored.
        Throws:
        javax.security.auth.login.LoginException - if the commit fails

      • initialize

        public void initialize​(javax.security.auth.Subject subject,
                       javax.security.auth.callback.CallbackHandler callbackHandler,
                       java.util.Map sharedState,
                       java.util.Map options)
        Initialize this 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.
        Specified by:
        initialize in interface javax.security.auth.spi.LoginModule
        Parameters:
        subject - the Subject to be authenticated.
        callbackHandler - is ignored
        sharedState - is ignored
        options - are ignored

      • login

        public boolean login()
              throws javax.security.auth.login.LoginException
        Authenticate the Subject (phase one) by extracting the Spring Security Authentication from the current SecurityContext.
        Specified by:
        login in interface javax.security.auth.spi.LoginModule
        Returns:
        true if the authentication succeeded, or false if this LoginModule should be ignored.
        Throws:
        javax.security.auth.login.LoginException - if the authentication fails

      • logout

        public boolean logout()
