Subject [jira] [Created] (HTTPCLIENT-1129) Redirect and Kerberos authentication in conflict
Date Mon, 26 Sep 2011 15:06:28 GMT
Redirect and Kerberos authentication in conflict
------------------------------------------------

                 Key: HTTPCLIENT-1129
                 URL: https://issues.apache.org/jira/browse/HTTPCLIENT-1129
             Project: HttpComponents HttpClient
          Issue Type: Wish
          Components: HttpClient
    Affects Versions: 4.1.2
            Reporter: Harald Kirsch


We are using the HttpClient to connect to a Website that uses Kerberos-Authentication.

Beware this trigger word: Kerberos! I think this is *not* the problem, but please read on.

Here is the sequence of events:

Client: GET /
Server: Unauthorized.
Client: GET / and includes authentication.
Server: 302 to /something on the same host (this shows that in principle authentication works)
Client: GET /something,  does not include authentication
Server: Unauthorized

Client quits with 401-Unauthorized.

I would have expected one of the following instead:

1) Client immediately sends authorization information with the redirected GET /something
2) Client re-requests the /something with authorization after 401-Unauthorized.

We could get around the problem by setting the ConnectionReuseStrategy to a constant false.

It would be great if someone could tell me if HttpClient works as expected or whether there
is a bug or misconfiguration lurking.

Thanks,
Harald.
