If you want users to log in only if they already exist in your system, and prevent new users from being created automatically, follow these steps:
Configuration Steps:
- Go to the Configured Provider in the plugin settings.
- Click on Advanced Settings for the selected provider.
- Scroll down to the User Creation section.
- Disable the toggle for Allow User Creation.
Note: This ensures that only existing users can authenticate. If a user does not already exist in the system, they will not be able to log in.
