What is the purpose of theadmin.

Theadmin.authsetting in therun.propertiesfile is used to specify a fallback authentication method for the administrative console.

Exact Extract from official documentation:

“To define a fallback administrator authentication method if the OIDC token provider is unreachable, enable the admin.auth=native property in the run.properties file. This overrides any configured administrative authentication to basic authentication.”

This makes it clear that the purpose ofadmin.authis tooverrideany configured SSO for the admin UI and enforce native (basic) authentication instead.

Option Ais incorrect because theadmin.authsetting does not configure SSO. SSO for the admin UI is configured separately.

Option Bis incorrect because this setting does not apply to the administrative API; it specifically applies to the admin UI console.

Option Cis correct because it directly reflects the documented behavior:admin.authoverrides SSO configuration for the administrative UI and enables native authentication.

Option Dis incorrect because the setting does not enable automatic authentication. It still requires credentials, but falls back to basic auth.
