This test has a road warrior, ("road") connecting to VPN host east. It shows up from a random IP. It uses RSASIG to authenticate for phase 1. It then uses XAUTH to authenticate the phase 1.5. East is uses password based XAUTH using /etc/ipsec.d/passwd It then proceeds to phase 2. (see -04 for a case where aggressive mode is used) This test case confirms that XAUTH without ModeCFG does not end up with a partial PHASE 1 state. libreswan up to 3.21 suffered from this bug.
