git clone http://drupalcode.org/sandbox/Rory/1426848.git domain_access_login
This module depends on the Domain Access module.
It prevents users logging into domains that aren't assigned to them.
Known issues
This module does not currently prevent a user logging in with OpenID - using an OpenID identity to log in will bypass the form validation this module provides. Suggestions are welcome on how to address this.
