Restrict SSH user to one folder

[Noturns]

I need to create a SSH account for an subscription.
This account is not allowed to access other domains. How do i do that?

I know how to create an SSH account with remote access.
Is this possible and can someone give me some directions?

This solution works is not acceptable http://kb.odin.com/en/122286
Because the account also has access to system directories like "bin" and "var" below the "httpd" directory.

Can i duplicate the account and limit it to see only the subdomain directory?
