User can't access user databases in SQL Server. Can access only system databases
<p>I have created new user in SQL Server 2012 on one of my cloud machines. But when I try to access any database other than the system ones, they are not accessible. Showing dialog "<em>The Database XXX is not accessible</em>". </p>

<p>How can I access all the tables which are created by other users? OR how can I make user who has all the database object access?</p>
