Q: How do I configure Firefox to enable Kerberos authentication?

A:

  1. In the address bar, type about:config. If it brings up a warning page, click I'll be careful, I promise!
  2. Paste network.negotiate-auth.trusted-uris into the search field.
  3. Double click the preference and you should get a dialog box asking you to Enter string value.
  4. Enter the domain for which you want to enable Kerberos authentication, e.g. stanford.edu.
  5. You may need to repeat the procedure for the preference network.negotiate-auth.delegation-uris, although this is not required most of the time.

Q: Why does Heracles ask for my administrator password?

A: If Heracles detects that Google Chrome is your default browser, then it will attempt to automatically enable Kerberos authentication for it. However, permanently enabling Kerberos authentication for Chrome requires administrator access. If you do not need this feature or do not want to give Heracles administrator access, it is perfectly okay to click Cancel at the authorization prompt.
Note: When the authorization prompt comes up, the text in Heracles’ window shows which URL it is trying to whitelist. If this URL is not the URL that should be whitelisted, please contact me.
