function domain_settings_form_alter in Domain Access 6.2

Same name and namespace in other branches

1. 7.3 domain_settings/domain_settings.module \domain_settings_form_alter()
2. 7.2 domain_settings/domain_settings.module \domain_settings_form_alter()

Implement hook_form_alter()

This function checks the #submit value of the form to see if system_settings_form() has been invoked. If so, we may attach domain-specific settings to the form, if the user is permitted to use this module and the form is not on the administrator's denied list.
