William Hooper quoting Thiers and asking: >> BTW, 1 - I can browse normally on Mozilla (after explicit proxy >> authentication request), although It doesn't open https site above >> (probably a certificate issue). > Is this using just username:thiers, password:my_password_here ? > William Hooper Hi William, Since you asked, the whole Mozilla story is: When accessing first URL after opening Mozilla, login and password are required for authentication to the ISA server (proxy). I can browse normally on most sites but, when pointing to https://lists.linux.duke.edu/mailman/listinfo/yum I received a dialog box entitled 'Alert' with the msg: lists.linux.duke.edu could not be found. Please check the name and try again. When pointing to that same URL from IE or Opera on Windows, I receive some notification about irregular certificate, install it anyway and can then access normally. Maybe I should export the certificate from one of these and export to Moz ? Cheers Thiers
