Michael Osipov commented on HTTPCLIENT-1662:
--------------------------------------------
Colin, the provided code snippet is not correct. You cannot assume that a
simple substring will translate a DNS domain to a netbios domain. The best
solution is to query AD with LDAP for a proper translation. Windows does this
with a RPC. In your company, the forest root is {{COMPANY.NET}} and the
appropriate netbios name is {{COMPANY-NET}}. This will probably be your case.
> NTLM auth failed because NTLMEngineImpl strip domain to base domain name

> Key: HTTPCLIENT-1662
> URL: https://issues.apache.org/jira/browse/HTTPCLIENT-1662
> Project: HttpComponents HttpClient
> Issue Type: Bug
> Components: HttpAuth
> Affects Versions: 4.5
> Environment: HttpClient 4.3, 4.5
> A http site with NTLM auth
> A domain which Netbios name is not match domain name(e.g.
> domain=mydomain.com; netbios name= testdomain)
> Reporter: Colin
>
> When generate type 3 message, we change the domain name to base domain name:
> {code}
> // Use only the base domain name!
> final String unqualifiedDomain = convertDomain(domain);
> {code}
> {code}
> /** Strip dot suffix from a name */
> private static String stripDotSuffix(final String value) {
> if (value == null) {
> return null;
> }
> final int index = value.indexOf(".");
> if (index != -1) {
> return value.substring(0, index);
> }
> return value;
> }
> /** Convert domain to standard form */
> private static String convertDomain(final String domain) {
> return stripDotSuffix(domain);
> }
> {code}
> I got http 401 in my environment with correct credential and found the root
> cause is those code got wrong domain name so the domain controller return a
> NTLM sub status code 0xC0000064, which means " The username you typed does
> not exist!"
> The Netbios name of a domain is the "Pre Windows 2000 name" of the domain.
> Is there any issue to use full domain name?
