sigh. Thanks anyway, Sahoo. Nobody seems to know how to deal with this -
I've even pinged the tomcat-users alias and ... no response.
Then for now, I'll just use the roll-my-own-session approach, supplying
a username/password...until I get some better insight. If I break
through with something, I'll post the list.
