Single Sign-On Browser Settings

The University of Exeter Single Sign On Service enables you to avoid repeating your username and password for access to secure web pages and applications for which you are authorised.

Your browser may be capable of using your current Windows authentication information to automatically login to the Single Sign On Service but requires some configuration to be added to your browser.

Please follow the procedure below to permanently add the required configuration.

3. Double-Click on network.negotiate-auth.trusted-uris and set the value to
   sso.exeter.ac.uk
   Press OK to save the change.
4. Close all instances of Firefox and retry access.
