check the permissions on /usr/bin/kppp
kppp is a program that needs to be root to function, on my computer i see that 
i has the setuid permission, so it always runs as root, regardless of who 
starts it, maybe that's what you're missing?

-rwsr-xr-- 1 root dialout 546060 2012-04-06 12:39 /usr/bin/kppp

these commands should get you there:

sudo chown root:dialout /usr/bin/kppp
sudo chmod 4754 /usr/bin/kppp

after that, you should be able to run kppp as non-root, and it'll function.
