Eric Kerwin commented on HTTPCLIENT-2086:
-----------------------------------------
I believe I am hitting this as well. For the moment, I am able to address the
parser's output in a custom NTLMScheme that doesn't just look at challenge
value, but also looks at params.
I have no idea if that's acceptable, but here's how I'm doing it... (I don't
claim it is good...)
{code:java}
@Override
public void processChallenge(
final AuthChallenge authChallenge,
final HttpContext context) throws MalformedChallengeException {
Args.notNull(authChallenge, "AuthChallenge");
this.challenge = authChallenge.getValue();
if (this.challenge == null && authChallenge.getParams() != null &&
authChallenge.getParams().size() > 0) {
this.challenge = authChallenge.getParams().get(0).getName();
}
if (this.challenge == null || this.challenge.isEmpty()) {
...
{code}

> My Authentication endpoint returns an NTLM Message header like this:

> {code}
> if (!cursor.atEnd() && buffer.charAt(cursor.getPos()) == EQUAL_CHAR) {

> {code}
> When reading the first "=" char of the message, it interprets the value as a
> key-value pair. The first part of the NTLM message being the key and the
> second "=" the value.

> an AuthChallenge is later created with
> {code}
> new AuthChallenge(challengeType, schemeName, null, params.size() > 0 ? params

> {code}
> where {{value}} is null and params a list containing the NTLM message without
> the equals signs.
> Without the "==" the next auth step fails.
