Security Descriptor Definition Language

The security descriptor definition language (SDDL) defines the string format that the ConvertSecurityDescriptorToStringSecurityDescriptor and ConvertStringSecurityDescriptorToSecurityDescriptor functions use to describe a security descriptor as a text string. The language also defines string elements for describing information in the components of a security descriptor. Conditional access control entries (ACEs) have a different SDDL format than other ACE types. For ACEs, see ACE Strings . For conditional ACEs, see Security Descriptor Definition Language for Conditional ACEs . Want to try using Ask Learn to clarify or guide you through this topic?
