Issues when using the Mozilla Firefox
Enabling Kerberos Authentication in Firefox
Firefox does not automatically perform Kerberos authentication against any sites. You must manually add sites to a trusted sites list.
To enable Kerberos authentication in Firefox:
# Open Firefox and enter about:config in the address bar. Dismiss any warnings that appear.
# In the Search field, enter negotiate.
# Double-click the network.negotiate-auth.trusted-uris preference.
# This preference lists the trusted sites for Kerberos authentication.
# In the dialog box, enter the PeopleSoft domain, such as example.com or localhost.
# Click the OK button.
The domain that you just entered in the network.negotiate-auth.trusted-uris should now appear in Value column. The setting takes effect immediately; you do not have to restart Firefox.
