OpenID Connect
Atomic OSSEC (AEO) supports Single Sign On (SSO) via integration with OpenID Connect. A full list of certified providers is available at: https://openid.net/developers/certified/
SSO and OpenID Connect setup for the Atomic OSSEC web console are documented in Identity and enrollment under OpenID Connect (SSO).
That page also covers agent identity and enrollment (endpoint UUID/UID and manager modes) in one place.
