<h1 class="topictitle1">Troubleshoot assigning a user certificate</h1>
<div><div class="section"> <p>When you use the <span class="uicontrol">Assign a user certificate</span> task,
Digital Certificate Manager (DCM) displays certificate information for you
to approve before registering the certificate. If DCM is unable to display
a certificate, the problem might be caused by one of these situations: </p>
</div>
<ol><li><span>Your browser did not request that you select a certificate to present
to the server. This may happen if the browser cached a previous certificate
(from accessing a different server). Try clearing the browser's cache and
try the task again. The browser will prompt you to select a certificate.</span></li>
<li><span>This may also happen if you configure your browser so that it does
not display a selection list and the browser contains only one certificate
from a Certificate Authority (CA) in the list of CAs that the server trusts.
Check your browser configuration settings and change them, if necessary. Your
browser will then prompt you to select a certificate. If you cannot present
a certificate from a CA that the server is set to trust, you cannot assign
a certificate. Contact your DCM administrator. </span></li>
<li><span>The certificate that you want to register is already registered
with DCM. </span></li>
<li><span>The Certificate Authority that issued the certificate is not designated
as trusted for the system or the application in question. Therefore, the certificate
you are presenting is not valid. Contact your system administrator to determine
if the CA that issued your certificate is correct. If the CA is correct, the
system administrator may need to <span class="uicontrol">Import</span> the CA certificate
into the *SYSTEM certificate store. Or, the administrator may need to use
the <span class="uicontrol">Set CA status</span> task to enable the CA as trusted
to correct the problem.</span></li>
<li><span>You do not have a certificate to register. You can check for user
certificates in your browser to see if this is the problem. </span></li>
<li><span>The certificate that you are trying to register is expired or incomplete.
You must either renew the certificate or contact the CA that issued it to
resolve the problem.</span></li>
<li><span>The <span class="keyword">IBM<sup>®</sup> HTTP Server for i5/OS™</span> is
not correctly set up to do certificate registration using SSL and client authentication
on the secure Administrative server instance. If none of the previous troubleshooting
tips works, contact your system administrator to report the problem.</span></li>
</ol>
<div class="section"> <p>To <span class="uicontrol">Assign a user certificate</span>, you must
connect to Digital Certificate Manager (DCM) by using an SSL session. If you
are not using SSL when you select the <span class="uicontrol">Assign a user certificate</span> task,
DCM displays a message that you must use SSL. The message contains a button
so that you can connect to DCM by using SSL. If the message displays without
the button, inform your system administrator of the problem. The Web server
may need to be restarted to ensure that the configuration directives for using
SSL are activated. </p>
