A CA certificate with 2 or more certificates included in the CA certificate chain is being imported into OA using the pem.importCertificate API method.
After the method is executed, there are duplicate records in the
apache_certificates OA database table in case 2 or more certificates are passed as the
ca_cert parameter value.
The certificates that are included in the CA certificate chain and passed within the
ca_cert field are not separated or separated with a single line break (the
\012 character sequence).
Certificates must be separated with an empty line - two line breaks (the
\012\012 sequence) between CA certificates.
Documentation bug POA-111010: "pem.importCertificate API guide - add info about several CA certificates (certificates chain)" was reported to the OA maintenance team regarding this issue.
