Configuring CAS Authentication Login
# Overview
This section introduces the integration configuration process for CAS protocol authentication login. After configuring the integration of a CAS authentication source on the IDaaS platform, refer to this module to configure CAS authentication login. When accessing an application system, IDaaS will redirect to a third-party identity provider to complete identity authentication.
# Prerequisites
- Have administrative permissions for the application system of a third-party identity provider (IDP), and this identity provider supports CAS authentication.
- Have administrator permissions for the IDaaS Enterprise Center platform.
- The application has been integrated on the IDaaS platform.
- Have already configured a CAS authentication source on the IDaaS platform.
# Configuration Process

# Steps
# Configuring CAS Authentication for an Application
Log in to the IDaaS Enterprise Center platform. In the top navigation bar, select "Resources > Applications". Taking the User Center application as an example, select "User Center" and switch to the "Login Configuration" tab. Scroll down to CAS and enable the previously added CAS authentication source.

# Verifying CAS Authentication Login
The actual process of CAS authentication login is related to the "When no user is associated" option in Configuring a CAS Authentication Source. Please refer to the interface prompts for login.
Access the User Center. On the application system login page, select CAS authentication login.

The page will redirect to the CAS authentication platform. Enter the account and password registered on that platform to log in to the User Center.
