// Determine whether a client is trying to impersonate innappropriately
// This routine should only be called if a thread requesting impersonation
// is itself already impersonating a client of its own. This routine
// indicates whether the client is attempting to violate the level of
// impersonation granted to it by its client.
//
// Arguments:
//
// ImpersonationLevel - Is the impersonation level of the client's
// effective token.
//
// ServerIsRemote - Is a boolean flag indicating whether the client
// is requesting impersonation services to a remote system. TRUE
// indicates the session is a remote session, FALSE indicates the
// session is a local session. Delegation level is necessary to
// achieve a remote session.
//
// Return Value:
//
// TRUE - Indicates that the impersonation level of the client's client
// token is innapropriate for the attempted impersonation.
// An error (STATUS_BAD_IMPERSONATION_LEVEL) should be generated.
//
// FALSE - Indicates the impersonation attempt is not bad, and should
// be allowed.
