We have a system we are working on that has STS on Forms DMZ server. When walking through the documentation and on the Directory Server Endpoint Configuration Utility enabling 'Enable alternate service' there are no certificates to select from in the corresponding drop-down list. We do have a certificate installed on the machine from a trusted authority and the Service User has permissions on the certificate. Does anyone know why it would not be showing in the dropdown?
The certificate type is SHA256.
