On our server (Apache/Ubuntu18) we have a web app running which is a multi-tenant web app. So for every new client there will be a new tenant setup and it will create a new subdomain. So:
ClientA: A.domain.com (But want to access the app through their own company url. So A.nike.com) ClientB: B.domain.com (But want to access the app through their own company url. So A.adidas.com)
Because they want to use their own company URL, we did setup a wildcard SSL certificate for our web app and every time a company needs to be added to this list we will need to run Certbot to add and verify the domain to the list. But this is really a pain because like this we need to ask clients to add TXT records every time when we need to renewal the certificate.
Would it be possible to separately create SSL certificates for each company url, and configure the app/vhost to handle these certificates? So no wilcard ssl anymore but a ssl certificate for each company
