Method Detail

initialize

public void initialize(Subject subject,
                       CallbackHandler callbackHandler,
                       Map<String,?> sharedState,
                       Map<String,?> options)

Specified by:

initialize in interface LoginModule

Overrides:

initialize in class FileLoginModule

login

public boolean login()
              throws LoginException

Authenticate the user by getting the user name and password from the CallbackHandler.

Specified by:

login in interface LoginModule

Overrides:

login in class FileLoginModule

Returns:

true in all cases since this PAMLoginModule should not be ignored.

Throws:

FailedLoginException - if the authentication fails.

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

See Also:

LoginModule.login()

logUser

protected boolean logUser(String username,
                          String password)
                   throws LoginException

Throws:

LoginException - if authentication and group membership fails.

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).

Specified by:

commit in interface LoginModule

Overrides:

commit in class FileLoginModule

Returns:

true if this LDAPLoginModule's own login and commit attempts succeeded, or false otherwise.

Throws:

LoginException - if the commit fails.

See Also:

LoginModule.commit()

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 LDAPLoginModule'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

Overrides:

abort in class FileLoginModule

Returns:

false if this LoginModule's own login and/or commit attempts failed, and true otherwise.

Throws:

LoginException - if the abort fails.

See Also:

LoginModule.abort()

logout

public boolean logout()
               throws LoginException
