Hi list,
We are trying to integrate the STS into our solution for SSO but we
encountered an issue that is hard to solve.
For the moment, the token validator uses a callback to be able to
verify the correct username and password to deliver the token.
The problem appears when you need to store hashed passwords and check.
There would be needed some mechanism no to set the current password to the
WSPasswordCallback to be verified directly against the string value of the
password but to check it agains a hashed value.
The following code is coming from the PasswordCallbackHandler:
-----------------------------------------------------------------------------------------------------------------------------
public void handle(Callback[] callbacks) throws IOException,
UnsupportedCallbackException {
if (getPasswords() == null || getPasswords().size() == 0)
return;
for (int i = 0; i < callbacks.length; i++) {
if (callbacks[i] instanceof WSPasswordCallback) { // CXF
WSPasswordCallback pc = (WSPasswordCallback) callbacks[i];
String pw = getPasswords().get(pc.getIdentifier());
pc.setPassword(pw);
}
}
}
-----------------------------------------------------------------------------------------------------------------------------
The correct/original password and the one provided is evaluated at the
UsernameTokenValidator
(org.apache.ws.security.validate.UsernameTokenValidator). Method:
verifyDigestPassword (called from the "verifyPlaintextPassword" method).
-----------------------------------------------------------------------------------------------------------------------------
if (!origPassword.equals(password)) {
throw new
WSSecurityException(WSSecurityException.FAILED_AUTHENTICATION);
}
-----------------------------------------------------------------------------------------------------------------------------
I could imagine that it could be set a flag to indicate that the
password should be checked instead of compared and also the algorithm to be
used for the digest check.
Any suggestion about how this could/should be done? Any other idea?
Thanks in advance.
Fran.
