This read-write counter reports the number of times this authentication provider entry returned a successful authentication response, automatically resetting when the provider's type changes, and can also be cleared manually. An admin compares it against wwpLeosUserAuthProviderCalled to gauge that provider's success rate. For example, a low success count relative to a high called count for the RADIUS provider suggests many login attempts against RADIUS are failing, warranting a check of the RADIUS server or shared secret.
