Yes, it is very common that company groups that own several companies have one &frankly account for each company but only one global SSO Solution, so the same “IDP Metadata.xml” file can be uploaded to all those &frankly 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 &frankly account where they are registered.
