title: Authenticate against Active Directory in .NET Core 1.0 application?
body: <p>With the recent release of .NET Core 1.0, we're in the process of migrating our RC1 applications to the final release. The only piece we can't seem to figure out is how to integrate Active Directory authentication. </p>
  
  <p>Previously in the RC1 applications, we had used the System.DirectoryServices.AccountManagement library to handle the LDAP authorization queries. However, we can no longer mix this library with .NET Core v1.</p>
  
  <p>Generally, what is the best way to integrate Active Directory authentication into our applications using the libraries available for use in the .NET Core framework? IdentityServer, some other third party service like Auth0 or something else?</p>
