This might not be the correct location for this, but I try anyway.
I have problems finding out how to authenticate users in each thread using JMeter. Via the website I post username and password through j_security_check. I tried to simulate a login by creating a HTTP Request in JMeter that has the path: hostname/j_security_check. The parameters are j_username with value and j_password with value.
I found out that it actually does the authentication, but JMeter gives be an error: "408 - The time allowed for the login process has exceeded......". I have even tried with one thread only cause I thought it didn't create a new session for each thread. That didn't help.
Does anyone have any experience with this? And know how to handle such authentication using JMeter.
