PPP-Dialup: ioctl(PPPIOCGUNIT): Operation not permitted

[matthschulz@gmx.net]

I'm trying to use my working (as root) ISP-Dialupconnection as an normal
user.

I got following in ppp.log:

I'm in the group dip and all files in /etc/ppp, /etc/ppp.chatscript, pon
and poff are owned by dip.

(P.S. The entry for dip is only in gshadow, not in passwd or passwd-)

What's wrong?
