Authentication tester failing to recognize session cookie?

[Adam Risch]

I'm trying to setup an automation framework to scan one of my company's web apps, and when testing the authentication script in the authentication tester, it's failing seemingly on the session handling (see attached image)?

I've watched the Firefox browser that opens up, and Zap appears to login successfully. When I record the diagnostics I get this:

You can see the JSESSIONID cookie is present, and this token is enabled under tools->options->http sessions. I tried changing the session management method for the "Authentication test" context from "auto-detect" to "cookie-based", but I got the same result, and the authentication tester appears to set it back to "auto-detect" automatically anyway. Am I missing something?
