Cool! This did the trick!
If anyone is interested, I have created a Portlet (extending
FileServerPortlet) which will pass the login userid and password to a URL. I
use it to display the logged-in user's calendar and todo list in portlets on
the Home page.
Should I post the code to the group here? Or just let anyone who wants it
send me their email address?
Anyway, thanks for the help, Vedran!
Steve B.
