Subject [jira] [Commented] (HTTPCLIENT-1545) Possible infinite loop when WindowsNegotiateScheme authentication fails
Date Tue, 19 Aug 2014 14:41:18 GMT

    [ https://issues.apache.org/jira/browse/HTTPCLIENT-1545?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14102251#comment-14102251

Ka-Lok Fung commented on HTTPCLIENT-1545:
-----------------------------------------

The likely reason why it isn't failing is because {{InitializeSecurityContext}} in {{getToken}}
isn't causing a {{Win32Exception}} to be thrown.

By any chance is your Windows machine not joined to a domain, i.e., it's a member of WORKGROUP?
Also, what version of Windows are you using?

I'll try to replicate the issue on a virtual machine that matches the conditions you specified.
In the end, I might be forced to add a JUnit assumption that the test can only run on Windows
machines that is a member of a domain.

> When {{WindowsNegotiateScheme}} authentication fails, it's possible for HttpClient to
retry the authentication in an endless loop because the {{continueNeeded}} flag is not set
to {{false}} when authentication fails.
> One possible way of causing authentication to fail is to use a service principle name
that is outside your Windows domain (e.g., HTTP/EXAMPLE.COM).
