title: Cross domain access in Sharepoint 2010
body: <p>There are two domains <code>A</code> and <code>B</code> (separate forests). <code>Sharepoint</code> site is deployed in <code>A</code> domain. Is it possible to user from domain <code>B</code> to get access to the site? </p>
  
  <p>As far as I understand <code>Sharepoint</code> is based on <code>Active Directory</code> accounts. Is it possible to have the user in both domains or are there any other alternatives?</p>
