HttpRetriever NEGOTIATE/NTLM

Hi I am trying to perform some HTTP requests, however I get the following errors:

WARN  HttpRetriever        0:91       NEGOTIATE authentication error: No valid credentials provided (Mechanism level: No valid credentials provided (Mechanism level: Failed to find any Kerberos tgt))
WARN  HttpRetriever        0:91       NTLM authentication error: Credentials cannot be used for NTLM authentication: org.apache.http.auth.UsernamePasswordCredentials

How can I provide valid credentials and/or make the NTLM authentication work?

Thanks.

Hi,

short anwser: we do not (currently?) support NTLM.

Best,
Philipp
