title: IdentityServer 4 with Active Directory on Premise
body: <p>Our client have many applications and they want to integrate it to just log once (single sign on), but they want that using active directory on premise they have their own server.</p>
  
  <p>We decided to evaluate identityserver so we found this <a href="http://docs.identityserver.io/en/latest/topics/windows.html" rel="nofollow noreferrer">http://docs.identityserver.io/en/latest/topics/windows.html</a> that identitserver 4 support active directory but here we dont see where we are going to put the LPAD//... route to connect to the active directory... so we are with doubts if identityserver supports or not Active directory or Maybe we cant undertand it very well. Thank you.</p>
