Method Detail

abort

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

Specified by:
abort in interface javax.security.auth.spi.LoginModule
Returns:
false if this LoginModule's own login and/or commit attempts failed, and true otherwise.
Throws:
javax.security.auth.login.LoginException - if the abort fails.

commit

public boolean commit()
               throws javax.security.auth.login.LoginException
This method is called if the LoginContext's overall authentication succeeded (the relevant REQUIRED, REQUISITE, SUFFICIENT and OPTIONAL LoginModules succeeded). If this LoginModule's own authentication attempted failed, then this method removes any state that was originally saved.
Specified by:
commit in interface javax.security.auth.spi.LoginModule
Returns:
true if this LoginModule's own login and commit attempts succeeded, or false otherwise.
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,
