Sobre o gerenciamento de identidade e acesso com o SAML de logon único
If you centrally manage your users' identities and applications with an identity provider (IdP), you can configure Security Assertion Markup Language (SAML) single sign-on (SSO) to protect your organization's resources on GitHub.
SAML single sign-on is available with GitHub Enterprise Cloud. For more information, see "GitHub's products."
SAML SSO gives organization owners and enterprise owners on GitHub a way to control and secure access to organization resources like repositories, issues, and pull requests.
After you configure SAML SSO, members of your GitHub organization will continue to log into their user accounts on GitHub. When a member accesses resources within your organization that uses SAML SSO, GitHub redirects the member to your IdP to authenticate. After successful authentication, your IdP redirects the member back to GitHub, where the member can access your organization's resources.
Enterprise owners can also enforce SAML SSO for all organizations in an enterprise account. For more information, see "Enforcing security settings in your enterprise account."
Note: Outside collaborators aren't required to authenticate with an IdP to access the resources in an organization with SAML SSO. For more information on outside collaborators, see "Permission levels for an organization."
Before enabling SAML SSO for your organization, you'll need to connect your IdP to your organization. For more information, see "Connecting your identity provider to your organization."
For an organization, SAML SSO can be disabled, enabled but not enforced, or enabled and enforced. After you enable SAML SSO for your organization and your organization's members successfully authenticate with your IdP, you can enforce the SAML SSO configuration. For more information about enforcing SAML SSO for your GitHub organization, see "Enforcing SAML single sign-on for your organization."
Members must periodically authenticate with your IdP to authenticate and gain access to your organization's resources. A duração desse período de login é especificado pelo seu IdP e geralmente é de 24 horas. Esse requisito de login periódico limita a duração do acesso e exige que os usuários identifiquem-se novamente para continuar.
To access the organization's protected resources using the API and Git on the command line, members must authorize and authenticate with a personal access token or SSH key. For more information, see "Authorizing a personal access token for use with SAML single sign-on" and "Authorizing an SSH key for use with SAML single sign-on."
The first time a member uses SAML SSO to access your organization, GitHub automatically creates a record that links your organization, the member's GitHub account, and the member's account on your IdP. You can view and revoke the linked SAML identity, active sessions, and authorized credentials for members of your organization or enterprise account. For more information, see "Viewing and managing a member's SAML access to your organization" and "Viewing and managing a user's SAML access to your enterprise account."
Organization members must also have an active SAML session to authorize an aplicativo OAuth. You can opt out of this requirement by contacting Suporte do GitHub or Suporte do GitHub Premium. GitHub does not recommend opting out of this requirement, which will expose your organization to a higher risk of account takeovers and potential data loss.
We offer limited support for all identity providers that implement the SAML 2.0 standard. We officially support these identity providers that have been internally tested:
- Active Directory Federation Services (AD FS)
- Azure Active Directory (Azure AD)
Some IdPs support provisioning access to a GitHub organization via SCIM. For more information, see "About SCIM."
Depois que o SAML SSO é habilitado, há várias maneiras possíveis de adicionar novos integrantes à organização. Os proprietários da organização podem convidar novos integrantes manualmente no GitHub ou usando a API. Para obter mais informações, consulte "Convidar usuários a ingressar na sua organização" e "Integrantes" na documentação do GitHub Developer.
You can use team synchronization to automatically add and remove team members in an organization through an identity provider. For more information, see "Synchronizing a team with an identity provider group."
Para provisionar novos usuários sem o convite de um proprietário da organização, você pode usar a URL
https://github.com/orgs/ORGANIZATION/sso/sign_up, substituindo ORGANIZATION pelo nome da sua organização. For example, you can configure your IdP so that anyone with access to the IdP can click a link on the IdP's dashboard to join your GitHub organization.
If your IdP supports SCIM, GitHub can automatically invite members to join your organization when you grant access on your IdP. If you remove a member's access to your GitHub organization on your SAML IdP, the member will be automatically removed from the GitHub organization. For more information, see "About SCIM."
GitHub does not support SAML Single Logout. To terminate an active SAML session, users should log out directly on your SAML IdP.
