[jira] [Resolved] (HTTPCLIENT-1266) Flag issues in NTLM
implementation prevent authentication on some servers
[ https://issues.apache.org/jira/browse/HTTPCLIENT-1266?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Oleg Kalnichevski resolved HTTPCLIENT-1266.
-------------------------------------------
Resolution: Fixed
Fix Version/s: (was: Future)
4.3 Alpha1
I cannot do much as far as this patch is concerned other than saying it looks well written and comes with abundance of test cases. I am committing the patch as is. The only thing I would do is reducing visibility of all non-public method to package private.

> At the ManifoldCF project, we've recently encountered two SharePoint servers (Windows 2008 Server R2) which seem to be configured in a way that the connector cannot authenticate with them using httpcomponents NTLM. It's worth noting that cURL succeeds, so the NTLM setup is apparently reasonable. Furthermore, the mcf patched version of commons-httpclient also fails in exactly the same way, so it looks like a long-standing issue.
> Working through the problem, it appears that the NTLM flags httpclient sends are, in some cases, inconsistent with the data we include. I am working on a httpclient patch, which I hope to be able to exercise in one of the client situations within the next week or two.
