Currently, we're not using a SAML auth plugin in our Moodle, though I am looking into the possibility. So far, this one looks promising to me and I'll be testing it soon: https://github.com/catalyst/moodle-auth_saml2
Instead, our Moodle is using what Okta calls "Secure Web Authentication". https://www.okta.com/resources/whitepaper/how-okta-integrates-applications-architectural-overview/

"Okta can leverage its Secure Web Authentication protocol to automatically log users into these internal web applications. When an internal web application is configured to delegate authentication to AD (the same source to which Okta delegates authentication), Okta captures the user’s AD password at login and automatically sets that password for that user in any applications that also delegate to AD. This allows users to simply click a link to access these applications, and then be logged in automatically."
