Hi everyone,

I'm currently working on a performance testing scenario involving IFS IEE, and I'm exploring the possibility of using Apache JMeter for this purpose.

Our IFS setup uses Active Directory Federation Services (ADFS) to enable Single Sign-On (SSO) with Windows credentials. This adds a challenge since the IEE client authentication is tightly integrated with Windows authentication (Kerberos/NTLM), which JMeter doesn't support out of the box.

I'd like to ask:

• Has anyone successfully connected or simulated IEE actions via JMeter in an ADFS-authenticated environment?
• Are there any known workarounds (e.g., session token replay, fallback to basic authentication)?
• Would it be more feasible to test via Aurena REST APIs instead of the IEE client in such a case?
• Any advice on how to structure the test plan or simulate real user activity under SSO constraints?

Appreciate any insights, examples, or best practices!
