When configuring an OpenStack provider with SSL security protocol, the user cannot provide the CA certificate chain that validates the endpoint. The only way today is to configure the CA certificate chain system wide on all CloudForms appliances that interact with the provider. This can be quite painful and is not user-friendly. The oVirt/RHV provider provides this capability and it would be great if the OpenStack provider allowed the user to specify the CA certificate chain when configuring the provider.
We already have documented the process, even though not optimal. Moving it to 5.12 to not affect provider code after code freeze.
