Current behaviour
The master admin portal signup form is accessible at /signup and it is at least partially functional in that it allows a user to sign up and a new Tenant is created. From the tests performed on RHOAM in MGDAPI-7000 it seems the activation link generated has the wrong domain which means the user cannot complete the signup process. This is good as we do not want this functionality outside of SaaS.
Expected behaviour
The signup page should not be accessible unless explicitly configured by the user to be so. This presents an undesired behaviour being exposed publicly (or within the network the domain can be resolved) and Tenants being created but inaccessible.
