To use the autologin feature, a browser has to be configured to use SPNego authentication for trusted Intranet sites. Furthermore proxy usage for Intranet sites should be disabled.

• Open the Firefox configuration page by typing “about:config” into the URLaddress bar. You can filter the configuration options by typing “nego” into the search bar.
• Change <font inherit/Courier New,Courier,monospace;;inherit;;inherit>network.negotiate-auth.delegation-uris</font> and <font inherit/Courier New,Courier,monospace;;inherit;;inherit>network.negotiateauth.trusted-uris</font> to the DNS domain name of the Stages server. You are free to use a smaller sub-part like in our example. The original domain name is <font inherit/Courier New,Courier,monospace;;inherit;;inherit>pkitbuild.er.methodpark.de</font>, but we used <font inherit/Courier New,Courier,monospace;;inherit;;inherit>methodpark.de</font> to enable SPNego for the whole company.
• Change the search filter to “proxy” and add an expression like <font inherit/Courier New,Courier,monospace;;inherit;;inherit>*.methodpark.de</font> to the property <font inherit/Courier New,Courier,monospace;;inherit;;inherit>network.proxy.no_proxies_on</font>.
