About automatic license synchronization
GitHub uses a unique-user licensing model. With the GitHub Enterprise plan, you're entitled to use both GitHub Enterprise Cloud and GitHub Enterprise Server. Your GitHub Enterprise Cloud allowance includes one deployment, on either GitHub.com or GHE.com.
GitHub determines how many licenses you're consuming based on the number of unique users across your deployments. Each user only consumes one license, no matter how many GitHub Enterprise Server instances the user uses, or how many organizations the user is a member of on your GitHub Enterprise Cloud deployment. This model allows each person to use multiple GitHub Enterprise deployments without incurring extra costs.
For a person using multiple GitHub Enterprise environments to only consume a single license, you must synchronize license usage between environments. Then, GitHub will deduplicate users based on the email addresses associated with their user accounts. GitHub deduplicates licenses for the GitHub Enterprise plan itself, and for GitHub Advanced Security products. See GitHub Enterprise Server에서 클라우드로 라이선스 사용량 동기화. For more information, see GitHub Connect 정보.
If you enable automatic user license sync for your enterprise, every week, GitHub Connect will automatically synchronize license usage between GitHub Enterprise Server and your enterprise on GitHub.com or GHE.com. You can also synchronize your license data at any time outside of the automatic weekly sync, by manually triggering a license sync job. For more information, see GitHub Enterprise Server에서 클라우드로 라이선스 사용량 동기화.
If you use multiple GitHub Enterprise Server instances, you can enable automatic license sync between each of your instances and the same enterprise account on GitHub Enterprise Cloud.
After you synchronize license usage, you can see a report of consumed licenses across all your environments in the enterprise settings on GitHub Enterprise Cloud. For more information, see GitHub Enterprise 계획의 사용량 보기.
You can also manually upload GitHub Enterprise Server user license information to GitHub Enterprise Cloud. For more information, see GitHub Enterprise Server에서 클라우드로 라이선스 사용량 동기화.
참고
To make troubleshooting easier, if you synchronize license usage and do not use Enterprise Managed Users, we highly recommend enabling verified domains for your enterprise account on GitHub Enterprise Cloud. See 엔터프라이즈의 도메인 확인 또는 승인 in the GitHub Enterprise Cloud documentation.
Enabling license synchronization
Before enabling license synchronization on your GitHub Enterprise Server instance, you must enable GitHub Connect. See GHE.com의 GitHub Connect 사용 or GitHub Connect를 GitHub.com에 활성화하기.

참고
If SAML with SCIM is enabled, the scim-admin setup user will not consume a license. For more information, see 사용자 관리를 위한 엔터프라이즈 관리 사용자 구성.
