Running N no of Jmeter threads in the order of sequence

Although i found a similar question, the answer wasn't satisfactory or perhaps doesn't work in my condition.

I have N no of threads to run with ramp up period of suppose 5. The login authentication for N users are being passed from a CSV file. The listener's report shows that thread 38 or any other thread runs before thread 1 i.e first iteration is of a thread no X (where X!=1). Using a loop controller doesn't seem to be the solution since my N users are all different. Below is the Test report of my test.

Thread           Iteration      Time(milliseconds)      Bytes   Success
ThreadNo 1-38         1         94551         67485         true
ThreadNo 1-69         2         92724         67200         true
ThreadNo 1-58         3         91812         66332         true
ThreadNo 1-12         4         92144         66335         true
ThreadNo 1-18         5         91737         66340         true
ThreadNo 1-17         6         93055         66514         true

So i want my iteration 1 to start with thread 1(ThreadNo 1-1).

Update: My test plan has the

Run thread groups consecutively(i.e. run groups one at a time)

as selected.
