> NTLM authentication error: Unexpected state: MSG_TYPE3_GENERATED
> ----------------------------------------------------------------
>
> Key: HTTPCLIENT-1882
> URL: https://issues.apache.org/jira/browse/HTTPCLIENT-1882
> Project: HttpComponents HttpClient
> Issue Type: Bug
> Components: HttpClient (async), HttpClient (classic), HttpClient
> (Windows)
> Affects Versions: 4.5.1
> Reporter: Matthias Schmalz
> Priority: Major
> Attachments: commonCase.log, rareCase.log
>
>
> We use the httpClient as part of our products to send http requests. One of
> our customers makes use of NTLM authentication. In most cases (as in
> commonCase.log), authentication works well.
> In rare cases (as in rareCase.log), the HttpAuthenticator logs
> {code:java}
> ERROR org.apache.http.impl.auth.HttpAuthenticator: NTLM authentication error:
> Unexpected state: MSG_TYPE3_GENERATED
> {code}
> Note that in rareCase.log the http client does not log anything between
> 10:08:48.990 and 10:10:23.577. We have analysed numerous cases where the
> authentication was and was not successful. We have observed that this period
> of inactivity occurs if and only if the NTLM authentication error is logged.
> Is this a bug?
> If not, could you please provide further information on why this is logged
> and how this can be avoided?
