The current authentication documentation lacks clarity on several important configuration behaviors:

• It does not state that the authentication mechanism can be used independently of the catalog provider.
• It does not explain that the LDAP authentication provider can fully replace the Keycloak provider.
• The documentation does not mention that the key value used in the OIDC configuration must match the value defined in the environment variables, which caused confusion during setup.

Update the authentication documentation to clearly describe these scenarios and configuration requirements, ensuring users understand provider independence and required key alignments.
