Comment 19 for bug 203973

Ok everything works it authenticates fine within GDM, add remove/programs and other places sudo would be needed. I only needed to logout to the GDM greeter for it too ask without me doing anything.

Interesting thing though, is that gnome-terminal stopped asking me to auth at all when I run sudo commands within it.

Also sudo is required to even verify the fingerprint (sudo tf-tool --verify)

As for the (sudo /usr/lib/pam-thinkfinger/pam-thinkfinger-enable) command I cannot verify whether its valid as mine was already enabled and the script said as much.

Hope this helps.
