Having added the users concerned to group dip, I would reinstall
the ppp package to correct all the file permissions which are
probably now all screwed up. (If that doesn't do it, install it,
purge it and reinstall it.)
As pppd *is* setuid, you should get the permissions right.
Not to do so may leave security holes open, and may even cause
pppd to refuse to run (it checks permissions on some files).
