Hello Cyrus,

Ok, then the server should be sending you a WWW-Authenticate headed for Digest that does NOT contains a "qop=..." option in it. Can you check what you are sending back to the server? The client should NOT be sending back a "qop=..." if the server did not send one.

Then that might be the problem. The server always returns the client a 'Qop' value in the "WWW-Authenticate" header. I will send you a text dump of the exchange in a few minutes. Best regards, Kervin
