Question

User-1042970710 posted

Hi Friends,

I simply want to authenticate the username and password with my Domain's AD...  I don't want to use Identity Framework...

What is the best way to achieve this  can I simply write a class method to authenticate?   Can anyone give me working example?

Regards;

Imran Jalali.

You can try to use windows authentication. However, that will only work if the server you run this on is joined to the domain (or a trusted domain).

If not, then you will have to use Forms Authentication, where the user enters their username and password, and you authenticate against AD in your code via LDAP. There are two ways to do this in .NET Core:

1.If you will only run this on a Windows server, then you can install and use the Microsoft.Windows.Compatibility NuGet package.

2.Use the third-party Novell.Directory.Ldap.NETStandard.

And you can refer to this link about the answers on this question that describe how to implement both solutions.
