When multiple domains point to same host, user accounts can be restricted to a certain domain only, following these steps:

- change the HTTP server item's User Connection Group to @AutoHostHttp on Preferences -> Ip/Servers page
- add new user connection groups named as the domain FQDN ( wst0.intranet.local and wst0.intranet2.local in this example)

- add new login page entries on Preferences -> Webinterfcace page, Options panel, as the domain FQDN prepended with an asterisk (*)

Now we can select a User Connection group in User Manager and add user accounts into. These accounts will be restricted to log only when accessing one of these domain URLs.

 A special case of usage is when only one CrushFTP server instance is used as a forward proxy in front of multiple FTP servers belonging to different domains. We need to add a template account into each user connection group set up as described in this article
