Overview
SubInACL is a command-line tool that enables administrators to obtain security information about files, registry keys, and services, and transfer this information from user to user, from local or global group to group, and from domain to domain. For example, if a user has moved from one domain (DomainA) to another (DomainB), the administrator can replace DomainA\User with DomainB\User in the security information for the user's files. This gives the user access to the same files from the new domain.

SubInACL enables administrators to do the following:

• Display security information associated with files, registry keys, or services. This information includes owner, group, permission access control list (ACL), discretionary ACL (DACL), and system ACL (SACL).
• Change the owner of an object.
• Replace the security information for one identifier (account, group, well-known security identifier (SID)) with that of another identifier.
• Migrate security information about objects. This is useful if you have reorganized a network's domains and need to migrate the security information for files from one domain to another.
