DigiCert will deprecate the Organizational Unit (OU) field to simplify certificate ordering.
To comply with industry standards, DigiCert will retire the Organizational Unit (OU) field for all public TLS/SSL certificates by the end of August 2022. 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.
