);

Parameters

hSession [in]
Handle to the session returned by the OpenNtmsSession function.

Return Value

This function returns one of the following values.

Value	Meaning
ERROR_ACCESS_DENIED	The privileges required to modify the security descriptor are denied.

Remarks

If an application uses SetNtmsObjectSecurity to set the discretionary access-control list (ACL) of an object, the application must have WRITE_DAC permission or be the owner of the object.

If an application uses SetNtmsObjectSecurity to set the system ACL of an object, the SE_SECURITY_NAME privilege must be enabled for the application. For more information, see the SetPrivateObjectSecurity function. For more information on RSM security, see RSM Security.
