Hi Gustavo, you can find information about setting up SSO’s for your users here:
https://sdk.gooddata.com/gooddata-ui/docs/7.1.0/sso.html, the sso provider is tied to your domain and it would allow the user to sign in to the domain itself. It would depend on how many workspaces this user has access to in your domain. Could you provide some more details as to your use case?
