How to Load Test OpenId Secured Websites

OpenId enables users to be authenticated using a single ID. The OpenId provider (OP) is the third party that authenticates a user signing in with an identificator.

OpenId is an open standard and decentralized authentication protocol. It is one of the few technologies for single sign-on (SSO) with token based authentication. This post will describe the implementation of JMeter scripts for load testing websites that use the OpenId protocol to authenticate users. We have already discussed the implementation of JMeter scripts for load testing SAML and OAuth, which are also authentication technologies.

OpenId enables users to be authenticated using a single ID. This means that a user who needs to be authenticated in a web service that supports OpenId doesn’t need to enter a unique login and password, but only an identificator. This identificator will be the same for all web services that support OpenId.

The authentication workflow requires the presence of a third party that confirms to the web service that the provided identity is correct. That third party may provide the user related data to the web service as well.
