In the security descriptor definition language (SDDL), security descriptor string use SID strings for the following components of a security descriptor:
- Owner
- Primary group
- The trustee in an ACE
A SID string in a security descriptor string can use either the standard string representation of a SID (S-R-I-S-S…) or one of the string constants defined in Sddl.h. For more information about the standard SID string notation, see SID Components.
The following SID string constants for well-known SIDs are defined in Sddl.h. For information about the corresponding relative IDs (RIDs), see Well-known SIDs.
