Method Detail

initialize

public void initialize(Subject subject,
                       CallbackHandler callbackHandler,
                       java.util.Map<java.lang.String,?> sharedState,
                       java.util.Map<java.lang.String,?> options)
Initialize this LoginModule.

Specified by:
initialize in interface LoginModule
Parameters:
subject - the Subject to be authenticated.

callbackHandler - a CallbackHandler for communicating with the end user (prompting for usernames and passwords, for example). This particular LoginModule only extracts the underlying Windows64 system information, so this parameter is ignored.

sharedState - shared LoginModule state.

options - options specified in the login Configuration for this particular LoginModule.

login

public boolean login()
              throws LoginException
Import underlying Windows64 system identity information.

Specified by:
login in interface LoginModule
Returns:
true in all cases since this LoginModule should not be ignored.
Throws:
FailedLoginException - if the authentication fails.

LoginException - if this LoginModule is unable to perform the authentication.

commit

public boolean commit()
               throws 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 attempt succeeded (checked by retrieving the private state saved by the login method), then this method associates some number of various Principals with the Subject located in the LoginModuleContext. If this LoginModule's own authentication attempted failed, then this method removes any state that was originally saved.

Specified by:
commit in interface LoginModule
Returns:
true if this LoginModule's own login and commit attempts succeeded, or false otherwise.
Throws:
LoginException - if the commit fails.

abort

public boolean abort()
              throws LoginException

This method is called if the LoginContext's overall authentication failed. (the relevant REQUIRED, REQUISITE, SUFFICIENT and OPTIONAL LoginModules did not succeed).

If this LoginModule's own authentication attempt succeeded (checked by retrieving the private state saved by the login and commit methods), then this method cleans up any state that was originally saved.

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

logout

public boolean logout()
               throws LoginException
Logout the user.

This method removes the UsernamePrincipal, UserIDPrincipal, DomainPrincipal, DomainIDPrincipal, GroupIDPrincipals, PrimaryGroupIDPrincipal and NumericCredential that may have been added by the commit method.

Specified by:
logout in interface LoginModule
Returns:
true in all cases since this LoginModule should not be ignored.
Throws:
LoginException - if the logout fails.
