I have a KDC server setup on our networking doing login window authentication. My question is, is there a setting that will allow applications to auth off of kerberos also? For example the lock icons in the System Preferences windows that allow you to gain administrator priveleges, or when you install a application that requires admin privs. Any ideas if this can do done? To me it doesn't make sure to allow authentication from the login window and then have to use a different password to auth on the system when making changes. Thanks for the help.
