Error 13806<br>
Authentication from Windows 10 client fails when trying to use
just certificates but EAP-Mschapv2 it works fine. <br>
Error 13806, "IKE failed to find valid machine certificate"<br>
<br>
I followed the advise about certificate needs for windows.<br>
All the keys are of type ecdsa:<br>
<br>
server cert:<br>
Ipsec pki --pub --in serverKey.der --type ecdsa | ipsec pki
--issue --cacert caCert.der --cakey caKey.der --dn "O=xxx, CN=<a
moz-do-not-send="true" href="http://home1234.ddns.com">home1234.ddns.com</a>"
--san="<a moz-do-not-send="true" href="http://home1234.ddns.com">home1234.ddns.com</a>"
--flag serverAuth --flag ikeIntermediate > serverCert.der<br>
<br>
client cert:<br>
ipsec pki --pub --in clientKey.der --type ecdsa | ipsec pki
--issue --cacert caCert.der --cakey caKey.der --dn "O=xxx,
CN=client" > clientCert.der<br>
<br>
converted der files to pem and packaged them into pkcs12 file<br>
<br>
openssl pkcs12 -export -in clientCert.pem -name "client" -inkey
clientKey.pem -certfile caCert.pem -caname "xxx CA" -out
clientCert.p12<br>
<br>
the first time I imported caCert.pem and clientCert.p12 files
into windwos cert store I made a mistake and imported them into
the current user account.<br>
Deleted them and imported them into the "computer account".<br>
and checked that it looks as in the last two sreencaps at <a
moz-do-not-send="true"
href="https://wiki.strongswan.org/projects/strongswan/wiki/Win7Certs">https://wiki.strongswan.org/projects/strongswan/wiki/Win7Certs</a><br>
it says you have a private key that corresponds to this
certificate.<br>
<br>
the san and CN are same for the server.<br>
<br>
ipsec.conf settings are:<br>

# ipsec.conf - strongSwan IPsec configuration file<br>
<br>
# basic configuration<br>
<br>
config setup<br>
# strictcrlpolicy=yes<br>

Windows 10 is hosed in the head (as are other windows versions);
here's what I have, and it works -- but it took a while to figure it
out by turning debugging up and chasing what the two sides were
saying to each other. You do not want eap-mschapv2 unless you're
using a password; for a machine certificate you want eap-tls (which
may not be in your build; if not you will have to add it), and the
eap_identity clause is also required.<br>
<br>
Snip from ipsec.conf:<br>
<br>
conn WinUserCert<br>
left=%any<br>
leftsubnet=0.0.0.0/0<br>
leftcert=genesis.denninger.net.crt<br>
leftauth=pubkey<br>
right=%any<br>
rightsourceip=192.168.2.0/24<br>
rightauth=eap-tls<br>
eap_identity=%identity<br>
auto=add<br>
dpdaction=clear<br>
dpddelay=300s<br>
<br>
And then the cert must contain:<br>

Note that BOTH SAN and CN are set in the user certificate. SAN is
there because I use this cert/key pair for S/MIME as well. However,
if you don't set CN to the same thing (which is usually not done if
SAN is set) then Win10 will send the CN, whatever it may be (e.g.
the user's full name), and StrongSwan won't find the cert because
when it looks for it in the certificate store it compares against
SAN and the comparison fails.<br>
