For more information, see Controlling object access in Active Directory Domain Services.The last review of FastCopy here on this site dates back to 2008 when I reviewed version 3.30 of the application.

Active Directory Service Interfaces (ADSI) include routines to create and modify the contents of these ACLs. For more information, see Getting information from an ACL and Creating or modifying an ACL.ĪCLs also provide access control to Microsoft Active Directory service objects. To ensure that ACLs are semantically correct, use the appropriate functions to create and manipulate ACLs. For more information about SACLs, see Audit generation and SACL access right.ĭon't try to work directly with the contents of an ACL. An ACE in an SACL can generate audit records when an access attempt fails, when it succeeds, or both. Each ACE specifies the types of access attempts by a specified trustee that cause the system to generate a record in the security event log. For information about how to properly create a DACL, see Creating a DACL.Ī system access control list (SACL) allows administrators to log attempts to access a secured object.

For more information, see How DACLs control access to an object. The system checks the ACEs in sequence until it finds one or more ACEs that allow all the requested access rights, or until any of the requested access rights are denied. If the object's DACL has no ACEs, the system denies all attempts to access the object because the DACL doesn't allow any access rights. If the object doesn't have a DACL, the system grants full access to everyone.

When a process tries to access a securable object, the system checks the ACEs in the object's DACL to determine whether to grant access to it. The security descriptor for a securable object can contain two types of ACLs: a DACL and an SACL.Ī discretionary access control list (DACL) identifies the trustees that are allowed or denied access to a securable object. Each ACE in an ACL identifies a trustee and specifies the access rights allowed, denied, or audited for that trustee. An access control list (ACL) is a list of access control entries (ACE).
