Is there a way to prevent user creation when user is logged in using SSO to DOMO for the first time, and email of that user is not present in DOMO users database?
Under Admin > Authentication > SSO there's an advanced section where you can check "Only invited people can access Domo". This will prevent new users from being created and require you to manually add them to the instance.
Thank you @GrantSmith, that solved my problem. Will i be able to import new users trough DOMO Users API?
Yes, you can still create users, they just won't get automatically created when the login through SSO the first time.
Thank you very much for your help.
