Enterprise owners on GitHub Enterprise Cloud can control the requirements for authentication and access to the enterprise's resources.
You can choose to allow members to create and manage user accounts, or your enterprise can create and manage accounts for members with Entepriseで管理されているユーザ. If you allow members to manage their own accounts, you can also configure SAML authentication to both increase security and centralize identity and access for the web applications that your team uses.
After learning more about these options, to determine which method is best for your enterprise, see "Identifying the best authentication method for your enterprise."
The following options are available for account management and authentication on GitHub Enterprise Cloud.
- Authentication through GitHub.com
- Authentication through GitHub.com with additional SAML access restriction
- Authentication with Entepriseで管理されているユーザ and federation
By default, each member must create a personal account on GitHub.com. You grant access to your enterprise, and the member can access your enterprise's resources after signing into the account on GitHub.com. The member manages the account, and can contribute to other enterprises, organizations, and repositories on GitHub.com.
If you configure additional SAML access restriction, each member must create and manage a personal account on GitHub.com. You grant access to your enterprise, and the member can access your enterprise's resources after both signing into the account on GitHub.com and successfully authenticating with your SAML identity provider (IdP). The member can contribute to other enterprises, organizations, and repositories on GitHub.com using their personal account. For more information about requiring SAML authentication for all access your enterprise's resources, see "About SAML for enterprise IAM."
If you use a standalone organization with GitHub Enterprise Cloud, or if you don't want to use SAML authentication for every organization in your enterprise, you can configure SAML for an individual organization. For more information, see "About identity and access management with SAML single sign-on."
If you need more control of the accounts for your enterprise members on GitHub.com, you can use Entepriseで管理されているユーザ. With Entepriseで管理されているユーザ, you provision and manage accounts for your enterprise members on GitHub.com using your IdP. Each member signs into an account that you create, and your enterprise manages the account. Contributions to the rest of GitHub.com are restricted. For more information, see "About Entepriseで管理されているユーザ."
Both SAML SSO and Entepriseで管理されているユーザ increase security for your enterprise's resources. Entepriseで管理されているユーザ additionally allows you to control the user accounts for your enterprise members and restricts what the accounts are able to do. However, those restrictions may be unacceptable for your enterprise if they obstruct your developers' workflows.
To determine whether your enterprise would benefit more from SAML SSO or Entepriseで管理されているユーザ, ask yourself these questions.
- Do you want to control the user accounts for your users?
- Which identity provider does your enterprise use?
- Do your developers work in public repositories, gists, or GitHub Pages sites?
- Do your developers rely on collaboration outside of your enterprise?
- Does your enterprise rely on outside collaborators?
- Can your enterprise tolerate migration costs?
Entepriseで管理されているユーザ may be right for your enterprise if you don't want enterprise members to use their own personal accounts on GitHub.com to access your enterprise's resources.
With SAML SSO, developers create and manage their own personal accounts, and each account is linked to a SAML identity in your IdP. Entepriseで管理されているユーザ functions more like other familiar SSO solutions, as you will provision the accounts for your users. You can also ensure user accounts conform with your company identity, by controlling usernames and the email addresses associated with the accounts.
If you currently require your users to create a new account on GitHub.com to use with your enterprise only, Entepriseで管理されているユーザ might be right for you. However, SAML SSO may be a better option if using your IdP as the source of truth for your user and access management would add too much complexity. For example, perhaps your enterprise does not have an established process for onboarding new users in your IdP.
Entepriseで管理されているユーザ is supported for a limited number of IdPs, while SAML SSO offers full support for a larger number of IdPs, plus limited support for all IdPs that implement the SAML 2.0 standard. For the list of supported IdPs for each option, see "About Entepriseで管理されているユーザ" and "About SAML for enterprise IAM."
You can use Entepriseで管理されているユーザ with an unsupported IdP only if you federate the unsupported IdP to a supported IdP to use as an integration point. If you wish to avoid this extra complexity, SAML SSO may be a better solution for you.
To prevent enterprise members from accidentally leaking corporate-owned content to the public on GitHub.com, Entepriseで管理されているユーザ imposes strong restrictions on what users can do. For example, 管理されているユーザアカウント cannot create public repositories, gists of any visibility, or GitHub Pages sites that are visible outside the enterprise. For a full list of restrictions, see "Abilities and restrictions of 管理されているユーザアカウント."
These restrictions are unacceptable for some enterprises. To determine whether Entepriseで管理されているユーザ will work for you, review the restrictions with your developers, and confirm whether any of the restrictions will hinder your existing workflows. If so, SAML SSO may be a better choice for your enterprise.
管理されているユーザアカウント can only contribute to repositories within your enterprise. If your developers need to collaborate in repositories outside your enterprise, even private repositories, to complete their work, Entepriseで管理されているユーザ may not be right for your enterprise, and SAML SSO may be a better solution.
With SAML SSO, you can give access to specific repositories to people who are not members of your IdP's directory, by using the outside collaborator role. This can be especially useful for collaborators that are external to your business, such as contractors. For more information, see "Adding outside collaborators to repositories in your organization."
With Entepriseで管理されているユーザ, the outside collaborator role does not exist. Your enterprise's resources can only be accessed by 管理されているユーザアカウント, which are always provisioned by your IdP. To give external collaborators access to your enterprise, you would have to use guest accounts in your IdP. If you're interested in Entepriseで管理されているユーザ, confirm with your developers whether this will hinder any of their existing workflows. If so, SAML SSO may be a better solution.
If your enterprise is new to GitHub.com, SAML SSO and Entepriseで管理されているユーザ are equally easy to adopt.
If you're already using GitHub.com with developers managing their own user accounts, adopting Entepriseで管理されているユーザ requires migrating to a new enterprise account. For more information, see "About enterprises with 管理されているユーザアカウント."
Although Entepriseで管理されているユーザ is free, the migration process may require time or cost from your team. Confirm that this migration process is acceptable to your business and your developers. If not, SAML SSO may be the better choice for you.
