I am using JMeter for QA automation tools. I've tried some ways to log in, read from blazemeter and jmeter manuals, read about oAuth. I also made JMeter use browser(firefox in my case) to log in (but I didn't understand that much) but still didn't pass it.

I also asked the IT person who is responsible for developing the site, but he never used JMeter before as well, so he didn't know how to solve it.

>The most response I got from JMeter is "redirecting" which as far as I know I have issue with the oAuth.

I tried it on demo.a  
Can anyone give solution?
