Set your browser defaults to delete history/cache/cookies on exit?

 Hi folks,

We have an interesting, yet troubling, problem.  We use Ellucian's
"Luminis" portal as part of our Banner system - and one of the "channels"
that we have on our Luminis portal is directly to Gmail, because we
outsourced our student email to Google about 2 years ago.  What we have
discovered is:

   1. "Student A" walks up to an open kiosk system in our Admissions area
   and logs in to Luminis with their own credentials
   2. "Student A" clicks on the Gmail "channel" in the Luminis portal and
   checks their email
   3. "Student A" finishes reading their email and just closes the active
   window, (ie, clicks on the "X" in the upper right corner of the window) and
   walks away....
   4. Now - "Student B" walks up to the same open kiosk - they open a new
   browser window and is prompted to login to Luminis with their own
   credentials
   5. "Student B" clicks on the Gmail channel in the Luminis portal to
   check their email
   6. PROBLEM - what "Student B" finds is that they are NOT in their own
   email - in fact, "Student B" has full access to "Student A's" email,
   because the cookie left behind by Google with the first student has kept
   the session active, even once the browser is closed.


....and the browser doesn't seem to matter.  It works this way in IE, Chrome
- all versions, apparently.

We've run this problem all the way up to Ellucian *and* Google.  Google
says everything is "working as designed" - there's no way to keep the
cookie from remaining resident and active, as long as the system isn't
rebooted.  The only thing that *appears* to work is making the student
explicitly logout of the Luminis session when they are done.....but - since
these systems are setup to be self-service kiosks, there's not always
someone there to remind students to "log off before you leave", so we have
students closing the window thinking that they've "logged off", but the
next student steps up, logs in, and gets the previous student's email.

The problem doesn't seem to occur with any other "channels" - and we've
tried just about everything within the browser, with the Gmail settings,
popup blockers, security settings on the OS, etc.  Ellucian seems to be
very perplexed by our inquiries - seems that no one else is experiencing
this except us....??

Anyone else see or experience anything like this?

Anyone else already *solve* a problem like this?

Thanks for your time and consideration.....
