The document outlines the implementation of a web-based authentication provider called 'CCI Connect' that authenticates users against an LDAP server using OAuth 1.0. It highlights features such as centralized control of user access, security mechanisms, and flexibility for third-party applications. Users only log in once, as their authentication details are not shared with third-party apps, and they can revoke access when needed.

Slide 1
Authentication Server (OAuth2 or similar)
The objective of this presentation is to implement an Authentication
provider that can be used simply to authenticate users only once. This
may be like the one you use for authenticating yourself on
Facebook, LinkedIn, or Google.
The authentication should be Web-based and/or API-based and should
authenticate against our LDAP Server.
This provider should also remember which third-party systems are
authorized to authenticate against this server and what information, if
any, shared.
Authentication Client
Once a user is authenticated, they should not be required to enter login
details again in this system.
If the user is not logged in, a login screen should be
presented similar to Facebook connect or Google login.
Authentication will be done on Authentication provider
server and client will get no username/password ever.

Features
Security
• OAuth1.0
Control
• Centralized authentication process
• Centralized controlling of shared Active Directory
protected resources
Flexibility and Ease of Use
• Third party apps can use any OAuth1.0 client API

15. Slide 15
Features in detail…
Security
• For each access third party app has to follow OAuth1.0
protocol
• Uses HMAC – SHA1
• No user password is shared with third party app
Control
• User can revoke access to remembered browsers from
CCI connect
• Third party apps can be registered or removed
• Activity monitoring on CCI connect
Flexibility and Ease of Use
• No need to use HTTPS to implement OAuth protocol
• All data returned from CCI connect is in JSON format in
case of successful authentication
