My server team wants to stop using AD for authentication and start using SAML. In a test system, we implemented SAML. But I am no longer able to login with the 'admin' user. My domain id has the admin role in Splunk Enterprise 6.6. Will I lose any functionality by never being able to login as the 'admin' user? Is there something that only that user can do, but someone with the admin role cannot do?
