Getting this error: An unexpected error has occurred when trying to use single sign on.

I have a user who can not log in and is getting this error. Has anyone else experienced this?

We have tried the following:

  • Have cleared cookies
  • Using Google Chrome
  • Have logged out and back in
  • Was able to log in fine last week but now getting this error 2 days in a row and can not log in.
  • Have submitted a ticket with tech support
