如何获取用户的访问控制或权限?,如果用户在第三方服务中进行了身份验证

How to obtain Access controls or permissions for the user?, If the user is authenticated in the third party services

如果用户在 AEM 实例中不可用并通过 SAML 在第三方服务中进行身份验证,如何获取用户的访问控制或权限? AEM 是否允许对 AEM 中不可用的用户设置或应用权限?

根据SAML Integration Documentation

Limitations
User Must Exist in AEM Users logging in via the handler must exist, or if missing must be created in, AEM (“Autocreate CRX Users” must be checked). This is because the Sling authentication framework, which the SamlAuthenticationHandler is a part of, extracts user credentials from the SAMLResponse and logs into the JCR repository using those credentials.

也参考这个link on Adobe AEM forum
