12 years ago Disabling automatic account creation has been implemented in version 1.0.3. To get the equivalent of a list of permitted users, simply create accounts for the permitted users and disable automatic account creation
In many use cases, only a subset of the email user accounts on a domain should be permitted access to Joomla!.
One possible (simple) implementation is to restrict login to user accounts which already exist in Joomla!, such that administrators must create the account in Joomla! before login is permitted.
