What is IAM for GitHub?
Administrators who configure a GitHub Enterprise Server instance can use local accounts and built-in authentication on the instance. Alternatively, to centralize identity and access for an enterprise's web applications, administrators can configure an external authentication method. If you use SAML, you can optionally provision user accounts on the instance from your identity provider (IdP) using System for Cross-domain Identity Management (SCIM).
Which authentication method are available to me?
The following authentication methods are available for GitHub Enterprise Server.
Built-in authentication
Quando você usa a autenticação interna para sua instância do GitHub Enterprise Server, cada pessoa cria uma conta pessoal a partir de um convite ou de uma inscrição. To access your instance, people authenticate with the credentials for the account. For more information, see Configurar a autenticação integrada.
External authentication
If you use an external directory or identity provider (IdP) to centralize access to multiple web applications, you may be able to configure external authentication for sua instância do GitHub Enterprise Server. For more information, see the following articles.
Observação
Você pode usar SAML ou LDAP, mas não ambos.
If you choose to use external authentication, you can also configure fallback authentication for people who don't have an account on your external authentication provider. For example, you may want to grant access to a contractor or machine user. For more information, see Como permitir a autenticação interna para usuários de fora do seu provedor.
How does provisioning work?
If you configure built-in authentication, CAS, LDAP, or SAML, GitHub Enterprise Server creates a user account when an authorized person signs into the instance, or "just in time" (JIT). Optionally, if you use SAML, you can provision user accounts from your identity provider (IdP) using SCIM. For more information, see Sobre o provisionamento de usuário com SCIM no GitHub Enterprise Server.
