unfortunately, the only reliable way to make it appear one JMeter is 10 different IP addresses is to modify the TCP header. Even if you change the HTTPHeader, if the webserver uses reverse lookup, it will figure out it is the same machine. Your best option is to use 10 machines to hit the same server. Is there a particular reason the single signon uses the IP address? I ask because users behind a NAT will appear to the be the same user, unless you use something more reliable to determine it is an unique visitor. For example, some use MAC address. That's probably not the answer you're looking for, but testing single sign-on application can be tricky, since security is inherently an issue. For a single sign-on to be good, it has to make it hard or impractical to spoof. Otherwise the single sign-on wouldn't be worth anything. peter lin

Lets think that there are 10 users accessing this application from 10 different machines. Thereby the application reads 10 different IP addresses corresponding to these 10 different users. My actual problem is simulating these 10 users from the JMeter. When I am using 10 users from the JMeter, all the 10 users are sending the same IP, there by only the last user is accessing the application and the remaining are not accessing the application i.e. they are logged out as the Single Sign On is enabled. So is there any way I can assign 10 different IPs for 10 Users by changing some classes of JMeter? Please give me suggestions in achieving this functionality.
