Introducing Security Identifier (SID) field via our GCC Enterprise user interface

What is a Security Identifier (SID)?

A Security Identifier (SID) is a unique identification number that a computer or domain controller uses to identify a user. It can be generated by using the command 'whoami /user' from a Windows computer." You will see your SID in your command prompt like this:

Where can I add this?

The GCC EPKI User Interface will be updated to accommodate the SID (Security Identifier) parameter for a user to provide a value by December 11, 2023. You will find this field in the Certificate Identity Details tab at the time of ordering your certificate, as shown below. This will be optional. ​​​​

Why is it being introduced?

To address a certificate-based authentication vulnerability in domain controllers, Microsoft has published a requirement change to support security identifiers for Certificates used for authentication purposes.

You will be required to use this field for all Authentication Certificates from February 11, 2025, onwards.

What do I do?

We recommend that you add this new SID field to your authentication Certificate and take advantage of this new update. Once added, GlobalSign will be able to issue Certificates that contain this necessary Non–Critical Extension Security Identifier information in your Certificate.
