Can I have several Employee Surveys accounts with only one global SSO?

Yes, it is very common that company groups that own several companies have one Employee Surveys account for each company but only one global SSO Solution, so the same “IDP Metadata.xml” file can be uploaded to all those Employee Surveys accounts, however, every email address can only exist once and cannot coexist in different accounts, meaning that their credentials will be verified in the global SSO and once verified, they will be logged in the Employee Surveys account where they are registered.
