After SSO (chocolatechip) cookie validation on the slave the SSO cookie is resent, this time with cookie['master'] equal to FALSE (because it's set on the slave).
It's difficult to define in reproducible steps, but should authentication fail on the subsite, and the SSO cookie is reset, then the next requests will never authenticate, because the SSO cookie will no longer validate due to having been generated on the slave.
