ppp problem

[Alisdair McDiarmid <alisdair@letdown.demon.co.uk>]

i've got a wierd problem with ppp (the pon command to be
precise). look:

[root:/home/alisdair/development/c] # ls -l /etc/ppp/peers/green
-rwxrwxrwx   1 root     dip           575 Jun 20 03:37
/etc/ppp/peers/green
[root:/home/alisdair/development/c] # x
exit
[alisdair%letdown ~/development/c] $ cat /etc/ppp/peers/green
cat: /etc/ppp/peers/green: Permission denied

this is just a test example: i'm trying to get pon to work
normally. alisdair is a member of group dip, but why on earth
is the above happening?

tia,
