About IAM for GitHub AE
On GitHub AE, you provision user accounts from a SAML identity provider (IdP). You must configure SAML single sign-on (SSO) so people can authenticate to access your enterprise on GitHub AE.
GitHub AE uses SAML SSO for authentication. Enterprise owners must configure SAML SSO with a SAML identity provider (IdP) during initialization. For more information, see "About SAML for enterprise IAM."
To provision user accounts on GitHub AE, you must configure provisioning on your IdP using System for Cross-domain Identity Management (SCIM). For more information, see "Configuring user provisioning with SCIM for your enterprise."
