I will usually on first boot and while installing updates (from a console log in) use the administrator graphical log in to create a desktop user, which then becomes my default log in from second boot onwards (the policy being not to type an administrator password during an X11 session if at all possible, logging in to an administrator log in only from a console).
Now while applications like 'Install/Remove Software' and 'Users and Groups' correctly prompt for the password of the administrator log in even when logged in as a desktop user (they seem to be able to automatically deduce this somehow!), lite-* tools requiring an admin. log in assume an administrator is running the program in the first instance and duly prompt only for a password -- being logged in as a desktop user (without even any sudo rights) the program duly refuses to run.
I can however run lite-* admin. programs from a terminal as a desktop user, logging in as administrator with 'su -l <admin. user>' in the first instance, however it does leave the password exposed to key loggers (although running xterm selecting the 'Secure Keyboard' option is a way around this).
