Harald Kirsch updated HTTPCLIENT-1129:
--------------------------------------
Attachment: customAuthScheme.log
Hi Oleg,
we tried the code below and it threw an exception as shown in the attachment.
Harald.
DefaultHttpClient client = new DefaultHttpClient();
UsernamePasswordCredentials creds = new
UsernamePasswordCredentials("username", "password");
client.getCredentialsProvider().setCredentials(new
AuthScope(AuthScope.ANY_HOST, AuthScope.ANY_PORT, AuthScope.ANY_REALM,
AuthPolicy.SPNEGO), creds);
AuthSchemeFactory asf = new AuthSchemeFactory() {
public AuthScheme newInstance(HttpParams params) {
return new NegotiateScheme() {
@Override
public boolean isConnectionBased() {
return false;
}
};
}
};
client.getAuthSchemes().register(AuthPolicy.SPNEGO, asf);
HttpGet httphead = new HttpGet("http://moss-test/";);
HttpResponse response = client.execute(httphead); //throws an
IllegalStateException (see logs)
> 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.
