LoginModule
public class NTLoginModule extends Object implements LoginModule
ThisLoginModulerenders a user's NT security information as some number ofPrincipals and associates them with aSubject.This LoginModule recognizes the debug option. If set to true in the login Configuration, debug messages will be output to the output stream, System.out.
This LoginModule also recognizes the debugNative option. If set to true in the login Configuration, debug messages from the native component of the module will be output to the output stream, System.out.

Method Detail

initialize
public void initialize(Subject subject, CallbackHandler callbackHandler, Map<String,?> sharedState, Map<String,?> options)
Initialize thisLoginModule.- Specified by:
initializein interfaceLoginModule- Parameters:
subject- theSubjectto be authenticated.callbackHandler- aCallbackHandlerfor communicating with the end user (prompting for usernames and passwords, for example). This particular LoginModule only extracts the underlying NT system information, so this parameter is ignored.sharedState- sharedLoginModulestate.options- options specified in the loginConfigurationfor this particularLoginModule.
-
login
public boolean login() throws LoginExceptionImport underlying NT system identity information.- Specified by:
loginin interfaceLoginModule- Returns:
- true in all cases since this
LoginModuleshould not be ignored. - Throws:
FailedLoginException- if the authentication fails.LoginException- if thisLoginModuleis unable to perform the authentication.
-
commit
public boolean commit() throws LoginExceptionThis 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
loginmethod), then this method associates some number of variousPrincipals with theSubjectlocated in theLoginModuleContext. If this LoginModule's own authentication attempted failed, then this method removes any state that was originally saved.- Specified by:
commitin interfaceLoginModule- 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 LoginExceptionThis 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
loginandcommitmethods), then this method cleans up any state that was originally saved.- Specified by:
abortin interfaceLoginModule- 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 LoginExceptionLogout the user.This method removes the
NTUserPrincipal,NTDomainPrincipal,NTSidUserPrincipal,NTSidDomainPrincipal,NTSidGroupPrincipals, andNTSidPrimaryGroupPrincipalthat may have been added by thecommitmethod.- Specified by:
logoutin interfaceLoginModule- Returns:
- true in all cases since this
LoginModuleshould not be ignored. - Throws:
LoginException- if the logout fails.
