SPNEGO

Last week I had an issue that some Domino Server didn’t provide SSO through SPNEGO any longer (environment worked for over 2 years now). This environment uses the customized domcfg.nsf template of Andreas Artner , maybe it’s related, but I don’t think so, on Windows 7 with latest Internet Explorer 11 and Domino Servers 9.0.1 with latest fix pack.
