Configuring Firefox for Active Directory in Transparent mode or Bridged mode

When the web appliance uses Active Directory authentication in Transparent mode, and Web Cache Communication Protocol provides load balancing between two or more appliances, Firefox users are prompted to enter a username and a password once per appliance. To avoid these prompts, configure Firefox to connect automatically.
  1. In the Firefox address bar, type about:config .
  2. In the Filter text box type ntlm .
  3. Double click on network.automatic-ntlm-auth.trusted-uris to edit the field.
  4. Enter the hostname(s) of the web appliance(s).
