Method Detail

authenticate

boolean authenticate()

Performs authentication on the request. If authentication is REQUIRED then setAuthenticationRequired() should be called before calling this method. If the result indicates that a response has been sent to the client then no further attempts should be made to modify the response. The caller of this method is responsible for ending the exchange. If this method returns true it can still have committed the response (e.g. form auth redirects back to the original page). Callers should check that the exchange has not been ended before proceeding.

Returns:

true if either the request is successfully authenticated or if there is no failure validating the current request so that the request should continue to be processed, false if authentication was not completed and challenge has been prepared for the client.

login

boolean login(String username,
              String password)

Attempts to log the user in using the provided credentials. This result will be stored in the current AuthenticatedSessionManager (if any), so subsequent requests will automatically be authenticated as this user.

This operation may block

Parameters:

username - The username

password - The password

Returns:

true if the login succeeded, false otherwise

logout

void logout()

de-authenticates the current exchange.

setAuthenticationRequired

void setAuthenticationRequired()

Marks this request as requiring authentication. Authentication challenge headers will only be sent if this method has been called. If authenticate() is called without first calling this method then the request will continue as normal even if the authentication was not successful.

isAuthenticationRequired

boolean isAuthenticationRequired()

Returns true if authentication is required

Returns:

true If authentication is required

addAuthenticationMechanism

@Deprecated
void addAuthenticationMechanism(AuthenticationMechanism mechanism)

Deprecated. This method is now only applicable to SecurityContext implementations that also implement the AuthenticationMechanismContext interface.

Adds an authentication mechanism to this context. When authenticate() is called mechanisms will be iterated over in the order they are added, and given a chance to authenticate the user.

Parameters:

mechanism - The mechanism to add

getAuthenticationMechanisms

@Deprecated
List<AuthenticationMechanism> getAuthenticationMechanisms()

Deprecated. Obtaining lists of mechanisms is discouraged, however there should not be a need to call this anyway.

Returns:

A list of all authentication mechanisms in this context

isAuthenticated

boolean isAuthenticated()

Returns:

true if a user has been authenticated for this request, false otherwise.

getAuthenticatedAccount

Account getAuthenticatedAccount()

Obtain the Account for the currently authenticated identity.

Returns:

The Account for the currently authenticated identity or null if no account is currently authenticated.

getMechanismName

String getMechanismName()

Returns:

The name of the mechanism that was used to authenticate

getIdentityManager

@Deprecated
IdentityManager getIdentityManager()

Deprecated. Authentication mechanisms that rely on the IdentityManager should instead hold their own reference to it.

Obtain the associated IdentityManager to use to make account verification decisions.

Returns:

The associated IdentityManager

authenticationComplete

void authenticationComplete(Account account,
                            String mechanismName,
                            boolean cachingRequired)

Called by the AuthenticationMechanism to indicate that an account has been successfully authenticated. Note: A successful verification of an account using the IdentityManager is not the same as a successful authentication decision, other factors could be taken into account to make the final decision.

Parameters:

account - - The authenticated Account

mechanismName - - The name of the mechanism used to authenticate the account.

cachingRequired - - If this mechanism requires caching

authenticationFailed

void authenticationFailed(String message,
                          String mechanismName)

Called by the AuthenticationMechanism to indicate that an authentication attempt has failed. This should only be called where an authentication attempt has truly failed, for authentication mechanisms where an additional round trip with the client is expected this should not be called. Where possible the failure message should contain the name of the identity that authentication was being attempted for, however as this is not always possible to identify in advance a generic message may be all that can be reported.

Parameters:

message - - The message describing the failure.

mechanismName - - The name of the mechanism reporting the failure.

registerNotificationReceiver

void registerNotificationReceiver(NotificationReceiver receiver)

Register a NotificationReceiver interested in receiving notifications for security events that happen on this SecurityContext.

Parameters:

receiver - - The NotificationReceiver to register.

removeNotificationReceiver

void removeNotificationReceiver(NotificationReceiver receiver)

Remove a previously registered NotificationReceiver from this SecurityContext. If the supplied receiver has not been previously registered this method will fail silently.

Parameters:

receiver - - The NotificationReceiver to remove.
