In the domains section, you can set options for the default domain ("") in addition to creating new domains to establish a multi-tenancy server. For standard configuration, the root domain and other domains will be accessible like this :

🔗 https://servername:8080/ — Default domain

🔗 https://servername:8080/customer1 — Customer1 domain

🔗 https://servername:8080/customer2 — Customer2 domain

When a user setup many domains, the server considers each domain separately and each domain has separate user accounts, administrators, etc. If a domain has no users, the first created account will be administrator for that domain.
