NTLM Authentication

[yogimogi]

Hello,
This is not really an issue with this library as such, we just wanted to check how can this code be modified so that it uses NTLM authentication underneath.

We have set up a SQUID proxy server with Kerberos, but apparently, it always falls back to NTLM authentication when we route traffic to internet through it via a web browser. We concluded that looking at SQUID log files. Though we can potentially fix configuration issue, assuming there is one, we also wanted to make sure, we are able to write code for a proxy which solely uses NTLM authentication.

We tried modifying

Registry<AuthSchemeProvider> authSchemeRegistry = 
        		RegistryBuilder.<AuthSchemeProvider>create().register(AuthSchemes.SPNEGO, new SPNegoSchemeFactory(true)).build();

TO

Registry<AuthSchemeProvider> authSchemeRegistry = 
        		RegistryBuilder.<AuthSchemeProvider>create().register(AuthSchemes.NTLM, new NTLMSchemeFactory()).build();

but we get this error
WARNING: Authentication scheme Negotiate not supported

We tried a lot of different things, but code always tried Kerberos authentication and then it fails with 407 Proxy Authentication needed error.
