Solved
Hi,
Trying to configure AnyConnect with Certificate Authentication. Since there are no visible logs available from Meraki interface, I am unable to troubleshoot and understand what is really happening here. I have tried to contact Meraki support on several occasion, but have been met by agents without real knowledge or understanding about this, plus 1-2 hours wait time on the telephone with random disconnects. I guess beta features with beta support go hand in hand.
This gives me the opportunity to try and ask the Community to see if there is somebody out there that has a working configuration. I have been told by others that it should work, but they have not given any details about it so not sure. It seems so basic, but I just can't figure it out. Does anybody have some pointers?
I have not tested if {{DeviceName}} should be added to SAN, or that the issue is that I really need a (public) Root CA and issue SCEPman with Intermediate CA Certificate (but Meraki documentation does not really mention the need for it). Anybody knows?
My configuration is as follows:
- MX84 with 16.11 (tried 16.8 too)
- SCEPman CA certificate uploaded to Meraki
- Machine and User certificate successfully deployed to device, also root added to Trusted
- AnyConnect Client v4.10.00093 for Windows with Profile below (manual cert selection for testing)
<?xml version="1.0" encoding="UTF-8"?>
<AnyConnectProfile xmlns="http://schemas.xmlsoap.org/encoding/">
<ClientInitialization>
<AuthenticationTimeout>60</AuthenticationTimeout>
<AutomaticCertSelection>false</AutomaticCertSelection>
</ClientInitialization>
<ServerList>
<HostEntry>
<HostName>AnyConnect</HostName>
<HostAddress>***.dynamic-m.com</HostAddress>
</HostEntry>
</ServerList>
</AnyConnectProfile>
When connecting, attempting both Machine and User certificate, gives the following Error:
The causing Error in Event Log I assume:

Have you tried it with an Base64 encoded certificate from the CA?
Hi,
I recently tried to do that also. But without a CA.
With only a Self-Sign Root CA and a client certificate signed with this root CA.
It’s not the best way, but an easy way to get it done.
First, in Windows 10 with Powershell, generate a Root CA cert.
$cert = New-SelfSignedCertificate -Type Custom -KeySpec Signature -Subject "CN=MerakiRootCert" -KeyExportPolicy Exportable -NotAfter (Get-Date).AddYears(15) -HashAlgorithm sha256 -KeyLength 2048 -CertStoreLocation "Cert:\CurrentUser\My" -KeyUsageProperty Sign -KeyUsage CertSign
Don’t close your Powershell
This Self-sign root CA certificate will be stored in your user personal store.
Now export it on your desktop in Base64 format. No need to export private key.
Then Upload it on your Dashboard
Now
Create a client certificate signed by the Self-sign root ca.
New-SelfSignedCertificate -Type Custom -DnsName MerakiChildCert -KeySpec Signature -Subject "CN=MerakiChildCert" -NotAfter (Get-Date).AddYears(15) -KeyExportPolicy Exportable -HashAlgorithm sha256 -KeyLength 2048 -CertStoreLocation "Cert:\CurrentUser\My" -Signer $cert -TextExtension @("2.5.29.37={text}1.3.6.1.5.5.7.3.2")
That it.
If you want to deploy the certificate to other computers, you can export it and import it manually or with a GPO.
Regards,
