To comply with industry standards, Per the CA/B Forum, as of Sept 1, 2022 (9/1/22), public TLS certs will not have an OU, and will ignore OU in a request for public TLS.
DigiCert will retire the Organizational Unit (OU) field for all public TLS/SSL certificates by August 24th 2022.
August 3, 2022 - Is the last day Digicert will allow new orders, reissue, duplicate orders to be submitted with an OU. If you attempt to place a new order, reissue, or duplicate after this date, the OU will not be listed on the certificate.
DigiCert will deprecate the Organizational Unit (OU) field to simplify certificate ordering. The OU field allows optional metadata to be stored in a certificate, however, it’s intended purpose is extremely limited and is subject to validation requirements. To reduce confusion around this optional field and to help improve validation times, we are removing it from future ordering processes.
