wvdial for normal user

[christophe barbe <christophe.barbe@online.fr>]

In order to set a ppp connection as a normal user I have had myself in the
dip group (for pppd) and in dialout for my /dev/ttySx.

Is this safe ?

Now it works but I obtain this 

$ wvdial provider
...
--> PPP negotiation detected.
--> Warning: Could not modify /etc/ppp/pap-secrets: Permission denied
--> --> PAP (Password Authentication Protocol) may be flaky.
--> Warning: Could not modify /etc/ppp/chap-secrets: Permission denied
--> --> CHAP (Challenge Handshake) may be flaky.
--> Starting pppd at Tue Jan  4 23:37:56 2000

But the files are in the group root. Should I changed something or not ?
