About CAS authentication for GitHub Enterprise Server
CAS is a single sign-on (SSO) protocol that centralizes authentication to multiple web applications. For more information, see "Central Authentication Service" on Wikipedia.
After you configure CAS, people who use your GitHub Enterprise Server instance must use a personal access token to authenticate API or Git requests over HTTP(S). CAS credentials cannot be used to authenticate these requests. For more information, see "Creating a personal access token."
If you configure CAS, people with accounts on your identity provider (IdP) do not consume a user license until the person signs into your GitHub Enterprise Server instance.
If you want to allow authentication for some people who don't have an account on your external authentication provider, you can allow fallback authentication to local accounts on your GitHub Enterprise Server instance. For more information, see "Allowing built-in authentication for users outside your provider."
Username considerations with CAS
GitHub Enterprise Server normalizes a value from your external authentication provider to determine the username for each new personal account on your GitHub Enterprise Server instance. For more information, see "Username considerations for external authentication."
