org.acegisecurity.providers.jaas
Class SecurityContextLoginModule  

java.lang.Object
  org.acegisecurity.providers.jaas.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 javax.security.auth.spi.LoginModule that uses an Acegi 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 Acegi to authenticate against Jaas.
The SecurityContextLoginModule allows a Jaas based application to authenticate against Acegi. 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.

Constructor Detail

SecurityContextLoginModule

public SecurityContextLoginModule()

Method Detail

abort

public boolean abort()
              throws javax.security.auth.login.LoginException

Abort the authentication process by forgetting the Acegi Security Authentication.

Specified by:

abort in interface javax.security.auth.spi.LoginModule

---

commit

public boolean commit()
               throws javax.security.auth.login.LoginException

Authenticate the Subject (phase two) by adding the Acegi Security Authentication to the Subject's principals.

Specified by:

commit in interface javax.security.auth.spi.LoginModule

---

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 Acegi Security. Also ignores the sharedState and options parameters, since none are recognized.

Specified by:

initialize in interface javax.security.auth.spi.LoginModule

---

login

public boolean login()
              throws javax.security.auth.login.LoginException

Authenticate the Subject (phase one) by extracting the Acegi Security Authentication from the current SecurityContext.

Specified by:

login in interface javax.security.auth.spi.LoginModule

---

logout

public boolean logout()
               throws javax.security.auth.login.LoginException

Log out the Subject.

Specified by:

logout in interface javax.security.auth.spi.LoginModule

---

getAuthentication

org.acegisecurity.Authentication getAuthentication()

---

getSubject

javax.security.auth.Subject getSubject()
