```
protected NtlmPasswordAuthentication getNtlmPasswordAuthentication()
```
    An application extending this class must provide an implementation for this method that returns new user credentials try try when accessing SMB resources described by the getRequestingURL and getRequestingException methods. If this method returns null the SmbAuthException that triggered the authenticator check will simply be rethrown. The default implementation returns null.
