Adding a CA certificate to an edge gateway enables trust verification of SSL certificates that are presented to the edge gateway for authentication, typically the client certificates used in VPN connections to the edge gateway.
You usually add the root certificate of your company or organization as a CA certificate. A typical use is for SSL VPN, where you want to authenticate VPN clients using certificates. Client certificates can be distributed to the VPN clients and when the VPN clients connect, their client certificates are validated against the CA certificate.
When adding a CA certificate, you typically configure a relevant Certificate Revocation List (CRL). The CRL protects against clients that present revoked certificates. See Add a Certificate Revocation List to an Edge Gateway.
Verify that you have the CA certificate data in PEM format. In the user interface, you can either paste in the PEM data of the CA certificate or browse to a file that contains the data and is available in your network from your local system.
To use the vCloud Director tenant portal to work with edge gateway services, the edge gateway must be converted to an advanced edge gateway. You can do this on the edge gateway in the vCloud Director Web console or from the tenant portal. For details on performing this step from the tenant portal, see Convert an Edge Gateway to an Advanced Edge Gateway.
