letsencrypt wildcard

[petroniolopes]

Hi there,

Can I create a wildcard with letsencrypt, but using this ssl in a new account (domain), for example:
maindomain.com (installed wildcard letsencrypt here)

and create a new domain/user: subdomain1.maindomain.com
and create a new domain/user: subdomain2.maindomain.com
and create a new domain/user: subdomain3.maindomain.com
and create a new domain/user: subdomain4.maindomain.com

and have been using the same ssl (wildcard) those subdomains, but not creaded inside the same maindomain.com (not using login inside de user maindomain > subdomain)

did you get it ? is possible?
