OAuth 用户身份验证和 Active Directory 用户身份验证有什么区别？

Question

I want that only the authenticated users can access my web application (.net). For this, in my solution design I am proposing an Identity management system.

But I want to understand whether I should go with

OAuth authentication

or the Active Directory authentication

What is the difference between these two and which one should used when.

Answer 1

I guess you´re mixing concepts:

OAuth is basically delegation of the authorization to another application. It can be an application written by you/your team, or it can be the active directory. Finally, it can be the google login there is here in stackowerflow)

The authorization will generate a token and is the one used by the application to authorize each time.

What I think you are trying to compare is SAML with OAuth :

The main difference is what I told before, using OAuth you will trust the 3rd party application which the user is logged on.

SAML is an standard that achieves the Single sign on, federation and identity manager.

There is other differences

The Token generated

• SAML is an `XML
• OAuth is Json

The transport layer

• OAuth is limited to HTTP
• there is no limit for SALM

The main goal

• OAuth was fully designed to use into internet, to delegate the authorization to trusted companies.
• SAML was designed for enterprise scenarios.
