[Openvpn-users] ERROR: could not read Auth username from stdin

[<ci...@gm...>]

I keep receiving this message after trying to connect to my openvpn
server. My config is set to handle authentication
using a file which only has a line of code (exit 0;) for testing. From
the documentation exit 0 means a valid login but I
believe the file does not get called at all since the error clearly
states something related to credentials not being read
or transmitted. My config is as follows:

mode server
dev tun
proto tcp
port 1194

script-security 3

keepalive 10 120

plugin /usr/lib/openvpn/openvpn-auth-pam.so login

client-cert-not-required

auth.pl contents:


#!/usr/bin/perl


my $user = $ENV{username};
my $passwd = $ENV{password};

printf("$user : $passwd\n");
exit 0;


Whatever I try to do I get the same error: ERROR: could not read Auth
username from stdin


Any ideas?
