Check the box beside each access detail that you would like to validate. Check none to validate the license key only.

Use &lt;b&gt;Per Seat&lt;/b&gt; validation when you want to restrict the licensing to a single hosted account. 

Use &lt;b&gt;Per Server&lt;/b&gt; validation when you want to restrict the licensing to a single server with one or many hosted accounts.

It is generally a good idea &lt;b&gt;not to mix&lt;/b&gt; per seat and per server validation. However, it is entirely possible to do just that. Mixing the two will nullify the benefits of per server, but will strengthen per seat validation.
