Cause

This issue can occur if the subject in the Name box matches the name of the certification authority (CA).

The subject's CN is string-compared and binary-compared to the issuer's name. If the full DN names are available, these names are compared before a certificate is issued. Comparison does not depend on the actual encoding of the characters in the subject's name.
