Need help to validate user against Active Directory & LDAP in ASP .NET Core Application

Hi,

I have started using ASP .NET Core Web Application with .NETCoreApp V1.0.

Now my requirement is to take a username and credentials from login screen and validate it against a active directory and LDAP.

If we have to use simple .net framework app then I can easily add references of System.DirectoryServices.AccountManagement; and start using PrincipalContext.

but How to achieve above requirement in ASP .NET Core app.

Thanks
