I am new to AACC real-time data API. I am using the downloaded sample C++ code to test the API, but NIrtd_Login fails with error code 60006, invalid user id. Our server admin told me that the user and password were correct, and I could log in AACC through browser with the user and password. But the sample C++ code always fails when calling NIrtd_Login and return code is 60006. Can someone help me, please?

Thank you very much in advance?
