Get the list of mTLS Authenticators that are configured to authenticate certificates for the specified mTLS Identity Provider.

An mTLS Identity Provider always has 1 mTLS Authenticator configured automatically by default:

• The Default Authenticator is capable of authenticating certificates issued by the Certificate Authority of the mTLS Identity Provider.
• The Default Authenticator maps each authenticating certificate to an identity of accountType car in the realm
• The Default Authenticator uses the Subject.CN field from the certificate to identify and map to the carId field of the car
• The Default Authenticator is automatically created with a new app in the realm that is included in all access tokens provided by the authenticator
• The Default Authenticator is enabled by default when it is created
• The Default Authenticator and its corresponding app is automatically deleted when its mTLS Identity Provider is deleted

Access Control:

• The calling principal must have "readMtlsIdentityProviders" action permission for the resource "{realm}" in the "account" service.
• The calling principal MUST NOT include a project scope.
