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.

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
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.
