With Enterprise Managed Users service, organizations can connect identity providers such as Azure Active Directory and Okta directly to GitHub Cloud, which enables management of GitHub identity and access for employees, and helps to streamline processes like onboarding and user group management.
The move is perhaps intended to help organizations of all sizes to easily transition software development operations to the cloud.
About GitHub's Enterprise Managed Users Service
GitHub's Enterprise Managed Users service allows you to control the user accounts of enterprise members through identity provider (IdP).
And you can simplify authentication with SAML single sign-on (SSO) and deprovision user accounts for enterprise members, with users assigned to the GitHub Enterprise Managed User application in the IdP provisioned as new user accounts on GitHub and added to your enterprise. You can control usernames, profile data, team membership, and repository access from the IdP.
Also, team membership can be managed within an organization in your enterprise directly through your IdP, allowing you repository access using groups in your IdP and organization membership can be managed manually or automatically as managed users are added to teams within the organization.
You can grant managed users access to contribute to repositories within your enterprise, but managed users can't create public content or collaborate with other users, organizations, and enterprises on GitHub.
However, to use Enterprise Managed Users, you'll need a separate type of enterprise account with Enterprise Managed Users enabled. You can check the "About enterprises with managed users" for more information about creating this account.
