Web browser settings required by SSO


The Single Sign On (SSO) service requires that the following two options are enabled in your browser:

  • Session Cookies
  • JavaScript

These two option are often enabled in default browser configuration. Please note that the cookies need to be enabled only on the session (temporary) level - these cookies do not persist across browser restarts and cannot be used to track your past visits to various websites.

Please see the Browser section for further details on cookies and JavaScript and for instructions how to enable them.


Troubleshooting tips

If you encounter an error (Access Manager error) on login with SSO please clear your session cookies first. The instructions how to do it on various browsers are below. You can also try using an incognito /private browsing window - this can be accessed via the menu in your browser.


If you continue receiving an error (Access Manager error) even after you have restarted the browser and cleared the cache then please file a support issue with the CCS IT Help Centre.

If you receive "Authentication Failed" error please make sure your credentials are correct and your account is not locked. Your account may become locked by the  IT Security Office or it can be locked temporarily due to a number of invalid login attempts with wrong credentials. The latter case happens, for example, when a user has a mobile device set up to query GryphMail, the user changes the central password but does not update the password used by the mobile device, and as the mobile device continues querying email with wrong credentials every minute it causes the user to become locked out.
