SECURITY_QUALITY_OF_SERVICE

The SECURITY_QUALITY_OF_SERVICE data structure contains information used to support client impersonation. A client can specify this information when it connects to a server; the information determines whether or not the server may impersonate the client, and if so, to what extent.

typedef struct _SECURITY_QUALITY_OF_SERVICE { // sqos 
    DWORD Length; 
    SECURITY_IMPERSONATION_LEVEL ImpersonationLevel; 
    SECURITY_CONTEXT_TRACKING_MODE ContextTrackingMode; 
    BOOLEAN EffectiveOnly; 
} SECURITY_QUALITY_OF_SERVICE;

Members

Length: Specifies the size, in bytes, of this structure.
ImpersonationLevel: Specifies what the server may be told about the client, and how the server may represent, or impersonate, the client. Security impersonation levels govern the degree to which a server process can act on behalf of a client process. This member is a SECURITY_IMPERSONATION_LEVEL enumeration type value.
ContextTrackingMode: Specifies whether the server is to be given a snapshot of the client's security context (called static tracking), or is to be continually updated to track changes to the client's security context (called dynamic tracking). The value SECURITY_STATIC_TRACKING specifies static tracking, and the value SECURITY_DYNAMIC_TRACKING specifies dynamic tracking. Not all communications mechanisms support dynamic tracking; those that do not will default to static tracking.
EffectiveOnly: Specifies whether or not the server may enable or disable privileges and groups that the client's security context may include.
