title: Fatal: authentication failed for [GIT client]
body: <p>I use Windows on the clients and I have a stand-alone installation of GitLab-CE (through omnibus package), I'm having problem with authentication but it isn't a server problem, I have the problem only from one client, I can access from other clients without problems then the problem is in this client.</p>
  
  <p>When git needs authentication I get this error:</p>
  
  <pre><code>fatal: Authentication failed for 'http://sgit.emuasa.es/jros/PruebaGit1.git/'
  </code></pre>
  
  <p>I have created several repos in the server and when I do a <code>push</code> operation where git needs authentication the client shows me the authentication dialog (user and pwd prompt), I write my credentials and I get the same error. I can access to the gitlab frontend using the same credentials but I can't perform <code>push</code> (or <code>clone</code> from private repositories).</p>
  
  <p>I can access only if I put user and password in the remote using:</p>
  
  <pre><code>git remote delete origin
  git remote add origin http://USER:PASSWORD@sgit.emuasa.es/jros/PruebaGit1.git
  </code></pre>
  
  <p>Then I can access but I don't want to have the password visible in the remote list.</p>
  
  <p>I have tried to write only the user:</p>
  
  <pre><code>git remote delete origin
  git remote add origin http://USER@sgit.emuasa.es/jros/PruebaGit1.git
  </code></pre>
  
  <p>Git prompts me for the password but the result is the same:</p>
  
  <pre><code>fatal: Authentication failed for 'http://jros@sgit.emuasa.es/jros/PruebaGit1.git/'
  </code></pre>
  
  <p>I have clear the credential helper using:</p>
  
  <pre><code>git config --unset credential.helper
  </code></pre>
  
  <p>And I have erased the credential from Windows Credential Manager ... but I can't find the source of this problem ...</p>
  
  <p>It's a strange behaivor due to I use github and gitlab (online) repositories with no problem.</p>
  
  <p>I have uninstall and reinstall all git client applications (tortoisegit, GitExtension, GitKraken) and uninstall Git but nothing ...</p>
  
  <p>Can you help me? any ideas? What can I do?</p>
