Thanks for your answers Josh and Seb. So it is kind of SSO...but not really. Plus it looks like you do not have control of the URL that is populated on that sign-on screen. Thus not end user friendly and not ready for prime time. 
I have also tried tweaking the BOESystems.xml file to no avail.
This is very bad news and I hope SAP will rectify this in the near future.
Kindest regards,
Kelly
