Platform Services normally excludes certain special users from Authentication Services processing and Identity Provisioning. You can use the platform configuration file to override this or to specify additional users and groups to be excluded.
Users excluded from Authentication Services are authenticated using the local security system. Provisioning events are not processed for users and groups excluded from Identity Provisioning.
