Subject [jira] [Updated] (HTTPCLIENT-1266) Flag issues in NTLM implementation prevent authentication on some servers
Date Fri, 30 Nov 2012 17:33:58 GMT

     [ https://issues.apache.org/jira/browse/HTTPCLIENT-1266?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Karl Wright updated HTTPCLIENT-1266:
------------------------------------

    Description: 
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.

Please see CONNECTORS-572 for details and research results.
