Method Detail

initialize

  1. public void initialize(Subject subject,
  2. CallbackHandler callbackHandler,
  3. java.util.Map<java.lang.String,?> sharedState,
  4. 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).

sharedState - shared LoginModule state.

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

login

  1. public boolean login()
  2. throws LoginException
Authenticate the user (first phase).

The implementation of this method attempts to retrieve the user's AIX Subject information by making a native AIX system call.

Specified by:
login in interface LoginModule
Returns:
true in all cases (this LoginModule should not be ignored).
Throws:
FailedLoginException - if attempts to retrieve the underlying system information fail.
LoginException - if the authentication fails

commit

  1. public boolean commit()
  2. throws LoginException
Commit the authentication (second phase).

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 (the importing of the AIX authentication information succeeded), then this method associates the AIX Principals with the Subject currently tied to the LoginModule. If this LoginModule's 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

  1. public boolean abort()
  2. throws LoginException
Abort the authentication (second phase).

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

This method cleans up any state that was originally saved as part of the authentication attempt from the login and commit methods.

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

  1. public boolean logout()
  2. throws LoginException
Logout the user.

This method removes the Principals associated with the Subject.

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