Hello,
I have installed the IKEv2 VPN connection at my colleague's laptop and
he disappointingly noticed that there is no password authentication in
addition to certificate.
This is also akward because we would have to change all certificates if
i.e. one laptop configured for the Faculty VPN was lost or stolen. :-(
I tried to setup Windows 10 native VPN client with IKEv2 + username +
password and pam-authorize=yes in /etc/ipsec.d/ikev2.conf
What I receive is rather odd: it seems that certificate rightid is taken
as the username, instead of Windows-provided username and password:
Jan 20 09:45:03.533192: "MYCONN-ikev2-cp"[2] 193.198.186.218 #1: IKEv2
FAILED during pam_authenticate with 'User not known to the underlying
authentication modu
le' for state #1, MYCONN-ikev2-cp[2] user=CN=pc-mtodorov.alu.hr,
O=ALU-UNIZG.
Jan 20 09:45:03.533787: | PAM: #1: PAM-process completed for user
'CN=pc-mtodorov.alu.hr, O=ALU-UNIZG' with result FAILURE
I would like to authenticate users from Linux server's /etc/passwd. Is
that possible?
I failed to Google anything on IKEv2 PAM authentication.
My /etc/ipsec.d/ikev2.conf is rather standard, and it works perfectly
when I disable PAM auth:
