Profile

A security identifier (SID) is a variable-length unique value that identifies a security principal or a security group in a Windows Server operating system. A common SID is a set of SIDS that identify a generic user or a general group. Their values are the same in all operating systems.

This information can be used to troubleshoot security issues and can also be used to resolve potential display problems that may occur in the ACL editor. In the ACL editor, you might display a SID instead of a user or group name.
