Hi,

Basically what I need to do is to perform digest authentication. First thing I tried is the official example available here. But when I try to execute it(with some small changes, Post instead of the the Get method) I get a

org.apache.http.auth.MalformedChallengeException: missing nonce in challange
at org.apache.http.impl.auth.DigestScheme.processChallenge(DigestScheme.java:132)

When this failed I tried using:

DefaultHttpClient client = new DefaultHttpClient();
client.getCredentialsProvider().setCredentials(new AuthScope(null, -1, null), new UsernamePasswordCredentials("<username>", "<password>"));

HttpPost post = new HttpPost(URI.create("http://<someaddress>"));
        List<NameValuePair> nvps = new ArrayList<NameValuePair>();
nvps.add(new BasicNameValuePair("domain", "<username>"));
post.setEntity(new UrlEncodedFormEntity(nvps, HTTP.UTF_8));

DigestScheme digestAuth = new DigestScheme();
digestAuth.overrideParamter("algorithm", "MD5");
digestAuth.overrideParamter("realm", "http://<someaddress>");
digestAuth.overrideParamter("nonce", Long.toString(new Random().nextLong(), 36));
digestAuth.overrideParamter("qop", "auth");
digestAuth.overrideParamter("nc", "0");
digestAuth.overrideParamter("cnonce", DigestScheme.createCnonce());

Header auth = digestAuth.authenticate(new
      UsernamePasswordCredentials("<username>", "<password>"), post);
System.out.println(auth.getName());
System.out.println(auth.getValue());
post.setHeader(auth);


HttpResponse ret = client.execute(post);
ByteArrayOutputStream v2 = new ByteArrayOutputStream();
ret.getEntity().writeTo(v2);
System.out.println("----------------------------------------");
System.out.println(v2.toString());
System.out.println("----------------------------------------");
System.out.println(ret.getStatusLine().getReasonPhrase());
System.out.println(ret.getStatusLine().getStatusCode());

At first I have only overridden "realm" and "nonce" DigestScheme parameters. But it turned out that PHP script running on the server requires all other params, but no matter if I specify them or not DigestScheme doesn't generate them when I call its authenticate() method.

I've been struggling with this for two days, and no luck. Based on everything I think that the cause of the problem is the PHP script. It looks to me that it doesn't send a challenge when app tries to access it unauthorized.

Any ideas anyone?
