Please ignore my stupidity, I had a typo. Fixed and now working. But in
case anyone wants to know, 2nd call didn't have port, host, path..
var NTLMCall = function(options, callback){
var host = options.host;
var port = options.port;
var user = options.user;
var pass = options.pass;
var domain = options.domain;
var path = options.path||'/';
var hostname = options.hostname||require('os').hostname();
var head = function(options, callback){
options.method = 'HEAD';
var req = http.request(options, function(res){
callback(null, res.headers);
});
req.end();
};
// Generate Type 1 to send to server in HTTP Request:
var buf = ntlm.encodeType1(hostname, domain);
// Should be capturing the connection here for re-use
head({headers: {Authorization: 'NTLM ' + buf.toString('base64')}, host:
host, port: port, path: '/'}, function(err, headers){
var hdr = headers['www-authenticate'];
var m = /^NTLM (.*)$/.exec(hdr);
var inbuf = new Buffer(m[1], 'base64');
// Extract Type 2 from HTTP Response header, and use it here:
var serverNonce = ntlm.decodeType2(inbuf);
// Generate Type 3 to send as authentication to server:
var buf = ntlm.encodeType3(user, hostname, domain, serverNonce, pass);
// Should be re-using the captured connection for this, it fails as is
var req = http.request({headers: {Authorization: 'NTLM ' +
buf.toString('base64')}, host: host, port: port, path: path}, function(res){
var data = '';
res.setEncoding('utf8');
res.on('data', function (chunk){
data += chunk;
});
res.on('end', function(){
callback(null, data);
});
res.on('error', function(err){
callback(err);
});
}).on('error', function(err){
callback(err);
});
req.end();
});
};
