<h3><a name="refprofiles"></a>User profiles and authorities</h3>
<p>WebSphere Application Server - Express uses two i5/OS user profiles by default:</p>
<ul>
<li>QEJB</li>
<li>QEJBSVR</li>
</ul>
<p>The QEJB user profile is is shipped as part of the i5/OS operating system. This user profile is used only when accessing validation list objects used for storing the encoded passwords used with WebSphere Application Server - Express. For more information on using validation list objects to store encoded passwords, see <a href="../sec/encoding.htm">Password encoding</a></p>
<p>The QEJBSVR user profile is created on your iSeries when you install WebSphere Application Server - Express. This profile is the default profile under which all application servers run. Directories and files used by WebSphere Application Server - Express are normally owned by user profile QEJBSVR. The WebSphere Application Server - Express runtime, administration tools, and Qshell scripts sets the ownership and authorities correctly on any objects created. If you create objects manually outside of the WebSphere Application Server - Express tools, or if you modify the authorities on objects used by WebSphere Application Server - Express, you must ensure QEJBSVR has the correct authorities to these objects.</p>
<p>When you create new directories for WebSphere Application Server - Express, the QEJBSVR user profile must have read and execute authorities (*RX) to those directories.</p>
<p><strong>Note:</strong> If you have specified another user profile to run your application servers, it is recommended that you specify QEJBSVR for its group profile. See <a href="../sec/isprfchg.htm">Run under a different profile</a> for more information.</p>
