Thanks Raúl.

Just to follow up on this, Blackboard have identified that the issue was caused by our customised login page which appeared to be missing some calls to Javascript libraries - including one to expire/remove cookies. If there's anyone who has customised their login page, could you let us know your Blackboard URL so we can have a look?

Thanks,
Julie

For us, in SP13 with load balancing in Windows environment isn't happened the same.

Hi Julie,

We're a Microsoft environment, so four load-balanced application servers on Windows Server 2008 R2, and the database is SQL Server 2008 R2.

Kind regards,

Sonya

Thanks Sonja. This is very useful to know as we're on SP12 as well. What operating system are you using for your application nodes and which database are you using?

Best wishes,
Julie

Hi Julie,

I have tested this and could not replicate the problem. Using LDAP and we're on SP12. I tested IE9 and latest versions of Firefox and Chrome on Windows 7. If it is pertinent, both of the test students I used had grades entered for all of the graded tests.

Kind regards,

Sonya

Dear All,

We have identified an issue whereby a student can view another student's grades if the first student does not close the browser after they log out. It would be good to know if this is affecting other institutions using LDAP authentication.

To test this on your system, log in as a student who has at least one grade available and access My Grades via the Global Navigation. You should see the grades for that student. Now click log out, but do not close the browser. Log in with a second student account who also has a grade available and view My Grades from the Global Navigation. Do you see two grades listed for the same assignment in the same course?

It would seem to us that the session cookies aren't being cleared and we are working with Blackboard to identify why. Closing the browser and/or logging off the computer does stop this from occurring.

I'd be grateful if some of you could test this out and let me know whether it occurs on your system too.

Best wishes
Julie
