public abstract class AbstractUsernameTokenAuthenticatingInterceptor
extends WSS4JInInterceptor

Base class providing an extensibility point for populating javax.security.auth.Subject from a current UsernameToken. WSS4J requires a password for validating digests which may not be available when external security systems provide for the authentication. This class implements WSS4J Processor interface so that it can delegate a UsernameToken validation to an external system. In order to handle digests, this class currently creates a new WSS4J Security Engine for every request. If clear text passwords are expected then a supportDigestPasswords boolean property with a false value can be used to disable creating security engines. Note that if a UsernameToken containing a clear text password has been encrypted then an application is expected to provide a password callback handler for decrypting the token only.

handleMessage

public void handleMessage(SoapMessage msg)
                   throws Fault

Description copied from interface: Interceptor

Intercepts a message. Interceptors should NOT invoke handleMessage or handleFault on the next interceptor - the interceptor chain will take care of this.

Specified by:

handleMessage in interface Interceptor<SoapMessage>

Overrides:

handleMessage in class WSS4JInInterceptor

Throws:

Fault

createSecurityContext

protected SecurityContext createSecurityContext(Principal p)

Overrides:

createSecurityContext in class WSS4JInInterceptor

doCreateSecurityContext

protected SecurityContext doCreateSecurityContext(Principal p,
                                                  Subject subject)

Creates default SecurityContext which implements isUserInRole using the following approach : skip the first Subject principal, and then check optional Groups the principal is a member of. Subclasses can override this method and implement a custom strategy instead

Parameters:

p - principal

subject - subject

Returns:

security context

setSubject

protected void setSubject(String name,
                          String password,
                          boolean isDigest,
                          String nonce,
                          String created)
                   throws org.apache.ws.security.WSSecurityException

Throws:

org.apache.ws.security.WSSecurityException

createSubject

protected abstract Subject createSubject(String name,
                                         String password,
                                         boolean isDigest,
                                         String nonce,
                                         String created)
                                  throws SecurityException

Create a Subject representing a current user and its roles. This Subject is expected to contain at least one Principal representing a user and optionally followed by one or more principal Groups this user is a member of. It will also be available in doCreateSecurityContext.

Parameters:

name - username

password - password

isDigest - true if a password digest is used

nonce - optional nonce

created - optional timestamp

Returns:

subject

Throws:

SecurityException

getSecurityEngine

protected org.apache.ws.security.WSSecurityEngine getSecurityEngine(boolean utNoCallbacks)

Overrides:

getSecurityEngine in class WSS4JInInterceptor

Returns:

the WSSecurityEngine in use by this interceptor. This engine is defined to be the secEngineOverride instance, if defined in this class (and supplied through construction); otherwise, it is taken to be the default WSSecEngine instance (currently defined in the WSHandler base class).
