Created attachment 8542315 [details] certificates_imported_with_same_nickname.zip User Agent: Mozilla/5.0 (Windows NT 6.1) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/39.0.2171.95 Safari/537.36 Steps to reproduce: (1) one root certificate is imported into the firefox certificate database. Certificate Manager -> Authorities-> Import ... (Import rootCA_key_cert.pem) (2) another certificate is imported as a server certificate Certificate Manager -> Servers -> Import...(Import 126.96.36.199.pem) (3) Open a terminal and list all the certs in the database certutil -L -d ... Actual results: The two certificates suddenly have the same nickname and thus I cannot use the certutil to modify the Trust Attributes as I like. I have to modify their attributes using the firefox Certificate Manager. In fact some other certificates with the same nickname may be rejected. Expected results: One certificate needs to be rejected when the second certificate is imported and some error messages need to be reported.
