Today I come here with an issue a coworker of mine faced on Elluminate (I think it’s called Blackboard Collaborate now). The problem he faced was a user who couldn’t create sessions getting the error “Session Authentication Token Invalid” or something to that effect. He was having trouble since it was only a single user who was having this issue.
I tried to help him even though I know nothing of Elluminate or Blackboard, but I thought that problems are still problems, which meant a logical solution would be there waiting to be found. I tried looking at .jnlp files that are downloaded upon hitting the create a new session link and tried to edit the username found in the file (the very last part of the file), but it was useless.
I tried clearing the browser’s cache and cookies but to no avail. What did work then? It’s a silly solution but it worked. The people at Elluminate should have handled this issue better, but as a developer myself, I know a lot of small issues can fall through the cracks.
The solution: you have to closely examine the first name and last name of the user having the problem. In my case, the last name had a double space between two names (the last name field had several names in it) and upon removing the extra space, the problem was resolved. You have to make sure that the source from where these names are read (in my case it was an active directory) and update the names there. I hope this helps anyone out there with the same issue.
