When you receive a certificate there is a possibility that the name on the certificate does not match the account it has been sent to. In such cases, a name mismatch message is shown on the digital certificate page, indicating to an inspector that there may be a problem with the certificate's validity.
The mismatch could be because:
The name mismatch algorithm does not check for an exact organisation name match. For example, it ignores variations in Ltd, Limited, etc and looks for a consistent phrase within the name.
A certificate issued in the name 'University Xyz, Department Abc' to an organisation called 'University Xyz' will not give rise to a name mismatch.
But if that was the first certificate issued, the organisation name would have been auotmatically set as the full university and department name. If a subsequent certificate was then issued to that organisation as "University Xyz, Department Def", a name mismatch would arise. The solution is to then edit the organisation name to just be 'University Xyz", and neither certificate will give rise to a name mismatch.
