Description: ------------ A request with NTML authentication using the current, authenticated user (CURLOPT_USERPWD ":") doesn't work, when doing a request to another host in the same domain. Settings the same credentials directly for CURLOPT_USERPWD works as expected. Test script: --------------- Script on "server1.domainXYZ", user already authenicated. Curl requests to "server1.domainXYZ" and "server2.domainXYZ". Version 1 (Server 1, explicitly setting the credentials of the current user): ... curl_setopt($ch, CURLOPT_URL, 'http://server1.domainXYZ/file.php'); curl_setopt($ch, CURLOPT_HEADER, 0); curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1); curl_setopt($ch, CURLOPT_HTTPAUTH, CURLAUTH_NTLM); curl_setopt($ch, CURLOPT_USERPWD, "domainXYZ\\userX:passwordY"); ... Version 2 (Server 1, using current user): ... curl_setopt($ch, CURLOPT_URL, 'http://server1.domainXYZ/file.php'); curl_setopt($ch, CURLOPT_HEADER, 0); curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1); curl_setopt($ch, CURLOPT_HTTPAUTH, CURLAUTH_NTLM); curl_setopt($ch, CURLOPT_USERPWD, ":"); ... Version 3 (Server 2, explicitly setting the credentials of the current user): ... curl_setopt($ch, CURLOPT_URL, 'http://server2.domainXYZ/file.php'); curl_setopt($ch, CURLOPT_HEADER, 0); curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1); curl_setopt($ch, CURLOPT_HTTPAUTH, CURLAUTH_NTLM); curl_setopt($ch, CURLOPT_USERPWD, "domainXYZ\\userX:passwordY"); ... Version 4 (Server 2, using current user): ... curl_setopt($ch, CURLOPT_URL, 'http://server2.domainXYZ/file.php'); curl_setopt($ch, CURLOPT_HEADER, 0); curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1); curl_setopt($ch, CURLOPT_HTTPAUTH, CURLAUTH_NTLM); curl_setopt($ch, CURLOPT_USERPWD, ":"); ... Expected result: ---------------- Version 1: works Version 2: works Version 3: works Version 4: works Actual result: -------------- Version 1: works Version 2: works Version 3: works Version 4: doesn't work In Version 1-3 the user name is correctly sent and logged in the IIS logs ("cs-username"). In Version 4, the user name in the IIS logs is empty ("-"), so no user name is sent by cURL. PatchesPull RequestsHistoryAllCommentsChangesGit/SVN commits

Still experiencing this in PHP 7.1.7, cURL version 7.54.1 When I explicitly specify my own username and password (which are the same for both source and destination servers) under CURLOPT_USERPWD it works perfectly, but with just ":" - authentication fails, error 401 The code is as follows: ... function file_get_contents_curl($url) { $curl = curl_init(); curl_setopt($curl, CURLOPT_URL, $url); curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1); curl_setopt($curl, CURLOPT_HTTPAUTH, CURLAUTH_NTLM); curl_setopt($curl, CURLOPT_UNRESTRICTED_AUTH, TRUE); curl_setopt($curl, CURLOPT_USERPWD, ":"); $data = curl_exec($curl); curl_close($curl); return $data; } ... Can you please advise?
