This article provides information on the possibility of using the same DN for different local certificates on the firewall.
The possibility of using the same DN for different local certificates on the firewall.

  • In a particular ScreenOS device, multiple certificates with the same Subject (or DN) name are not supported.

  • So, it is recommended to use a separate subject name for every key pair to avoid confusion.

  • Certain CA’s also have limitations on supporting multiple key pairs for the same subject name.

  • The ScreenOS device will auto-generate different CN values to ensure that the DN’s are unique. The device's serial number is included in this.
