[jira] [Commented] (HTTPCLIENT-1107) HttpClient does not retry
authentication when multiple challenges are present if the primary one
fails
[ https://issues.apache.org/jira/browse/HTTPCLIENT-1107?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13083958#comment-13083958 ]
David Waite commented on HTTPCLIENT-1107:
-----------------------------------------
Oleg, can you give more details on your envisioned approach?
I've been working on this for my own needs, but my approaches keep having issues due to the authentication schemes being split into processChallenge and authenticate, which are called in very different parts of the code.
One approach I thought of is to create every challenged scheme from the response and attempt to authenticate in order for making the headers out - but this will make an array of AuthState objects, which will break ClientContext.TARGET_AUTH_STATE (and the proxy equivalent).

> Components: HttpAuth

> I'm trying to request a page from IIS (6 and 7.5). If the IIS is configured with providers for "negotiate" and "ntlm" then the Negotiate authentication is tried and fails, but it does not then try to use the NTLM authentication which is what I require. If I removed "negotiate" as a provider from IIS and just use NTLM then all works well - but this is not a solution as I don't have control of the web servers.
