Before you enable smart card authentication, you must configure the reverse proxy on the vCenter Server system.
Reverse proxy configuration is required in vSphere 6.5 and later.
Copy the CA certificates to the vCenter Server system.
- Log in to the vCenter Server shell as the root user.
- Create a trusted client CA store.
This store contains the trusted issuing CA's certificates for client certificate. The client here is the browser from which the smart card process prompts the end user for information.
The following example shows how you create a certificate store on the vCenter Server.For a single certificate:
cd /usr/lib/vmware-sso/ openssl x509 -inform PEM -in xyzCompanySmartCardSigningCA.cer > /usr/lib/vmware-sso/vmware-sts/conf/clienttrustCA.pem
For multiple certificates:
cd /usr/lib/vmware-sso/ openssl x509 -inform PEM -in xyzCompanySmartCardSigningCA.cer >> /usr/lib/vmware-sso/vmware-sts/conf/clienttrustCA.pem
- Make a backup of the /etc/vmware-rhttpproxy/config.xml file that includes the reverse proxy definition, and open config.xml in an editor.
- Make the following changes and save the file.
<http> <maxConnections> 2048 </maxConnections> <requestClientCertificate>true</requestClientCertificate> <clientCertificateMaxSize>4096</clientCertificateMaxSize> <clientCAListFile>/usr/lib/vmware-sso/vmware-sts/conf/clienttrustCA.pem</clientCAListFile> </http>The config.xml file includes some of these elements. Uncomment, update, or add the elements as needed.
- Restart the service.
