The LSAPR_POLICY_PRIVILEGE_DEF structure specifies a privilege definition, which consists of a pairing of a human-readable name with a locally unique identifier (LUID).

 typedef struct _LSAPR_POLICY_PRIVILEGE_DEF {
   RPC_UNICODE_STRING Name;
   LUID LocalValue;
 } LSAPR_POLICY_PRIVILEGE_DEF,
  *PLSAPR_POLICY_PRIVILEGE_DEF;

Name: An RPC_UNICODE_STRING that contains the privilege name.

LocalValue: This field contains the LUID value assigned locally for efficient representation of the privilege. This value is meaningful only on the system where it was assigned.
