CoInitializeSecurity parameters:
- Without TurnOffCallSecurity: dwAuthnLevel = RPC_C_AUTHN_LEVEL_CONNECT (2); dwImpLevel = RPC_C_IMP_LEVEL_IMPERSONATE (3); pSecDesc = <by CSecurityDescriptor::InitializeFromThreadToken()>
- With TurnOffCallSecurity: dwAuthnLevel = RPC_C_AUTHN_LEVEL_NONE (1); dwImpLevel = RPC_C_IMP_LEVEL_IMPERSONATE (3); pSecDesc = NULL
COAUTHINFO* pAuthInfo in COSERVERINFO* passed to CoCreateInstanceEx (when machine name is not empty):
- Without TurnOffActivationSecurity: dwAuthnSvc = RPC_C_AUTHN_NONE; dwAuthzSvc = RPC_C_AUTHZ_NONE; pwszServerPrincName = NULL; dwAuthnLevel = RPC_C_AUTHN_LEVEL_NONE; dwImpersonationLevel = RPC_C_IMP_LEVEL_IMPERSONATE; pAuthIdentityData = NULL; dwCapabilities = EOAC_NONE;
- With TurnOffActivationSecurity: NULL
