The GSS-SPNEGO mechanism has been designed and introduced by Microsoft for use by Active Directory clients. It allows to negotiate an underlying Security Mechanism like Krb5 or NTLMSSP. However, the implementaion in cyrus-sasl is broken and never correctly interoperated with Microsoft servers or clients. This patch fixes the compatibility issue which is caused by incorrectly trying to negotiate SSF layers explicitly instead of using the flags negotiated by GSSAPI as required by Microsoft's implementation.
