Method Detail

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. This method is called by the LoginContext after this LoginModule has been instantiated. The purpose of this method is to initialize this LoginModule with the relevant information. If this LoginModule does not understand any of the data stored in sharedState or options parameters, they can be ignored.

Specified by:

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

Parameters:

subject - the Subject to be authenticated.

callbackHandler - a CallbackHandler for communicating with the end user (prompting for usernames and passwords, for example).

sharedState - state shared with other configured LoginModules.

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

login

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

Method to authenticate a Subject (phase 1). The implementation of this method authenticates a Subject. For example, it may prompt for Subject information such as a username and password and then attempt to verify the password. This method saves the result of the authentication attempt as private state within the LoginModule.

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

commit

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

Method to commit the authentication process (phase 2). 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 relevant Principals and Credentials with the Subject located in the LoginModule. If this LoginModule's own authentication attempted failed, then this method removes/destroys any state that was originally saved.

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

abort

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

Method to abort the authentication process (phase 2). 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 method), then this method cleans up any state that was originally saved.

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

logout

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

Method which logs out a Subject. An implementation of this method might remove/destroy a Subject's Principals and Credentials.

Specified by:

logout 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 logout fails
