Working with DirectoryServices in ASP.NET Core

Question

I am upgrading my ASP.NET Core RC1 application to RC2. I have some references to System.DirectoryServices and System.DirectoryServices.AccountManagement

You can use LDAP client library for .NET Standard 1.3
Compatible .NET runtimes: .NET Core, .NET Framework 4.6, ...
It works against any LDAP protocol compatible directory server (including Microsoft Active Directory).

private static bool LoginLdap(string username, string password)
{
    try
    {
        using (var conn = new LdapConnection())
        {
            conn.Connect("", 389);
            conn.Bind(LdapConnection.Ldap_V3, $"\\{username}", password);
        }
        return true;
    }
    catch (LdapException)
    {
        return false;
    }            
}

It works well for me. (in .NET Core 1.1.1)
