RE: UsernameToken Authentication with WSS4J

Hi,

The problem lies in WSS4J's processing of the password. If the incoming
password is hashed, then the CallbackHandler is used to retrieve a
password, which is then compared in the UsernameTokenProcessor. However,
if the password is in plaintext, as yours is, then all validation is
delegated to the CallbackHandler implementation.

See the javadoc here for further explanation:

http://ws.apache.org/wss4j/apidocs/org/apache/ws/security/processor/User
nameTokenProcessor.html#handleUsernameToken(org.w3c.dom.Element,%20javax
.security.auth.callback.CallbackHandler)

A JIRA has already been raised in WSS4J to improve the processing of
password:

http://issues.apache.org/jira/browse/WSS-54

Colm.

Hi Zarar,

Thanks for the reply.  I have added SAAJInInterceptor() to the
interceptor
chain and error has gone.  But the problem is that the service is
getting
invoked eventhough the passwords are not matching.  I want to understand
where does the password comparison occurs.  From logs I have the
following:

- Inside ValidateUserTokenInterceptor..
- principal.isPasswordDigest()= false
- principal.getNonce()= null
- principal.getPassword()= test
- principal.getCreatedTime()= null

The client is sending the password "test" while the CallbackHandler that
is
registered with the server is setting the password "test123".  

Thanks,
Durga
