I am not sure what you have tried. If you are on Windows, you can try using
the native providers. I think these are officially unsupported (probably
because constantly testing this would require too much money / effort), but
they work.
HttpClientBuilder builder;
<snip>
Registry<AuthSchemeProvider> authSchemeRegistry =
RegistryBuilder.<AuthSchemeProvider>create()
.register(AuthSchemes.NTLM, new
WindowsNTLMSchemeFactory(null))
.register(AuthSchemes.SPNEGO, new
WindowsNegotiateSchemeFactory(null))
.register(AuthSchemes.DIGEST, new
DigestSchemeFactory())
.register(AuthSchemes.BASIC, new
BasicSchemeFactory())
.build();
<snip>
builder.setDefaultAuthSchemeRegistry(authSchemeRegistry);
If you don't want to use them, you can subclass a CredentialsProvider.
However, if you are on Windows, I would try the canned versions at first and
see if you can get it to work.
(If you create your own CredentialsProvider)
builder.setDefaultCredentialsProvider(credentialsProvider);
Do you check these email threads?

Subject: HttpClient & NTLM-auth
I have read (and tested) hundreds (maybe only dozens ;)) of threads/posts
regarding HttpClient and NTLM auth.
-plain HttpClient (which I'd prefer!)
-jcifs
- spnego
- ...
None of the snippets I came along works out for me though, always ending up
with a 401.
Networksniffing shows, that no credential-negotiation/exchange is taking
place...
Taking the latest greatest HttpClient 4.5 what needs to be programmed and
configured(?) to get my java client to do NTLM authentication with a webservice
endpoint?
Do I need to follow anything mentioned here:

Thanks for your advices/hints
