title: Authentication to NuGet on Artifactory from within Visual Studio
body: <p>We have a local Artifactory Pro server that serves nuget packages and uses LDAP to authenticate all users. Using the Artifactory-NuGet from cmdline works perfectly, but when trying to use the package manager from Visual Studio, authentication fails. </p>
  
  <p>What I noticed is that Visual Studio tries to add a domain prefix after the first failed authentication attempt: Trying to login as 'user' fails, and then the login authentication windows contains 'DOMAIN\user' as username. </p>
  
  <p>I am not sure if the source of the problem is within Visual Studio or within Artifactory. I noticed that the web access to Artifactory does not accept usernames in the form "DOMAIN\user", even though I feel it should. </p>
  
  <p>So my question is: How do I authenticate to an LDAP-backed, Artifactory-provided authenticated NuGet server from within Visual Studio? </p>
