ppp, instructed by networkmanager (via nm-ppp-plugin) passed the option
usepeerdns to pppd (event if in the edit connection -> ipv4 settings ->
Automatic (ppp) address only is selected)
Proposed solution:
When "Automatic (PPP) address only" is selected, Network-Manager (nm-
ppp-plugin) should not pass the usepeerdns to pppd , thus disabling the
IPCP request for <ms-dns1 0.0.0.0> <ms-dns2 0.0.0.0>
** Affects: network-manager (Ubuntu)
Importance: Undecided
Status: New

Cannot connect to server that does not support pppd usepeerdns
