Subject [jira] [Commented] (HTTPCLIENT-1662) NTLM auth failed because NTLMEngineImpl strip domain to base domain name
Date Wed, 24 Jun 2015 11:49:04 GMT

    [ https://issues.apache.org/jira/browse/HTTPCLIENT-1662?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14599286#comment-14599286
] 

Michael Osipov commented on HTTPCLIENT-1662:
--------------------------------------------

I would rather disallow fully-qualified domain names and accept netbios ones. To make it reliable,
one would need to have the source code of {{DsGetDcName}} or try to find appropriate ones
in Samba.

> 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?
