In the past, we have had customers record and use applications with AngularJS and Shibboleth Single-SignOn technology. It was mostly a matter of correlation. Neoload 5.0 should work, but I can not guarantee there isn't some issue that would require using a later version, because we don't know the specifics of your application. I know that there will most likely be a "SAMLResponse" parameter you will need to handle, along with other parameters associated with the session and tokens, but it should not be too hard to figure out which.
