MBPM 9.5 eclsample.war for Java

Has anyone been able to successfully log in using the eclsample.war application included in the 9.x.x SDK (JAVA)?

The ECL Web Service is installed (IIS) during the process of installing MBPM 9.5.1. An instance of Tomcat is installed and the war file deployed in the tomcat container. The SAP scripts were installed and in proper order, along with debugging statements enabled. The debugging statements in the ELOG table shows there was a successful login (also confirmed in the ESSESSION table), but the "MetastormOperation" object in the eclsample application does not seem to recognize that the user has successfully authenticated (isAuthenticated() is always false)

IMetastormOperation bpm = new MetastormOperation();

String sessionId = bpm.login(user,pwd)

sessionId is always blank.

Am I missing anything?
