Better exception handling when kerberos is not supported #18

Open pfoppe opened 7 years ago

scenario - developer tries to access service protected with MS Negotiate... but Kerberos is not supported (like the SPN is not set correctly). the code tries NTLM but if there is no password the NTLM module throws an error. Capture this and raise our own error with this information blatantly stated.
