Hi Xi,

The Web Services binding uses UsernameToken by default for the 
authentication (as defined by the CMIS specification). Your server 
doesn't seem to support that.

To turn on HTTP authentication add this line:

parameters[SessionParameter.AuthenticationProviderClass] = 
"DotCMIS.Binding.NtlmAuthenticationProvider";

(Don't be confused by "NTLM". The authentication provider handles both, 
basic auth and NTLM.)


And a final note: Do not use the Web Services binding if you don't have 
to! It's slow and cumbersome.
