Why am I having trouble logging into Oncourse CL?

For basic login instructions, see Logging in. If you have trouble logging into Oncourse CL, check the following:

  • Make sure you are typing your username and passphrase correctly on the Central Authentication Service (CAS) login page. Both are case sensitive; verify that your Caps Lock key is not on.

  • Your CAS login may be stale. This can happen if you click your browser's Back button while in Oncourse CL. To resolve this issue, close and reopen your browser. (Instead of Back, use Cancel or the up arrow icon, as appropriate.)

  • Check that your browser is set up to use Secure Sockets Layer (SSL) connections. Most browsers are set up by default to use SSL.

  • Use your ADS domain account username and passphrase for authentication. If you do not have an ADS domain account, visit the Account Management Service page to request one. (If you don't know if you have one or not, see How can I find out which UITS computing accounts I have?)

  • If you have an ADS domain account, and are still having trouble connecting, try synchronizing your passphrases using the Passphrase Maintenance utility at: https://passphrase.iu.edu/

    Once you synchronize your passphrases, there will be a delay of about 20 minutes before you can log in.

  • If you are using a Guest account, check to see if you can log into CAS by trying to log into OneStart with your Guest account.

    • If you cannot log into CAS with your Guest account, you may not have activated your Guest account after creating it. In the email account you used to create your Guest account, look for a message with a subject such as "Activate your IU Guest account now". Click the link within the message to activate your account.

    • If you can log into CAS but cannot connect to Oncourse CL, you may not have been added to a course roster. In this case, you may receive the error, "Account not found." Ask your course instructor or the site owner to verify that you have been correctly added to the roster.

If you are still unable to access Oncourse CL, contact your campus Support Center for assistance.
