|
||
|
|
<div><p>Using Enterprise Identity Mapping (EIM) and Digital Certificate
|
||
|
|
Mangers (DCM) together allows you to apply a certificate as the source of
|
||
|
|
an EIM mapping lookup operation to map from the certificate to a target user
|
||
|
|
identity associated with the same EIM identifier.</p>
|
||
|
|
<div class="section"><p>EIM is an <span id="rzahuandeim.dita__eserver_logo"><a name="rzahuandeim.dita__eserver_logo"><!-- --></a><img src="eserver.gif" alt="eServer" /></span> technology that allows you to manage user identities in your
|
||
|
|
enterprise, including user profiles and user certificates. A user name and
|
||
|
|
password is the most common form of user identity; certificates are another
|
||
|
|
form of user identity. Some applications are configured to allow users to
|
||
|
|
be authenticated by means of a user certificate rather than by means of a
|
||
|
|
user name and password.</p>
|
||
|
|
<p>You can use EIM to create mappings
|
||
|
|
between user identities, which allows a user to authenticate with one user
|
||
|
|
identity and access resources of another user identity without the user having
|
||
|
|
to supply the needed user identity. You accomplish this in EIM by defining
|
||
|
|
an association between one user identity and another user identity. User identities
|
||
|
|
can be in various forms, including user certificates. You can either create
|
||
|
|
individual associations between an EIM identifier and the various user identities
|
||
|
|
that belong to a user represented by that EIM identifier. Or, you can create
|
||
|
|
policy associations, which map a group of user identities to a single target
|
||
|
|
user identity. User identities can be in various forms, including user certificates.
|
||
|
|
When you create these associations, user certificates can be mapped to the
|
||
|
|
appropriate EIM identifiers thereby making it easier for the certificates
|
||
|
|
to be used for authentication.</p>
|
||
|
|
<p>To take advantage of this EIM feature
|
||
|
|
for managing user certificates, you need to perform these EIM configuration
|
||
|
|
tasks before performing any DCM configuration tasks: </p>
|
||
|
|
</div>
|
||
|
|
<ol><li class="stepexpand"><span>Use the <span class="uicontrol">EIM Configuration</span> wizard in <span class="uicontrol">iSeries
|
||
|
|
Navigator</span> to configure EIM.</span></li>
|
||
|
|
<li class="stepexpand"><span>Create an EIM identifier for each user that you want to have participate
|
||
|
|
in EIM. </span></li>
|
||
|
|
<li class="stepexpand"><span>Create a target association between each EIM identifier and that
|
||
|
|
user's user profile in the local <span class="keyword">i5/OS™</span> user
|
||
|
|
registry so that any user certificates that the user assigns through DCM or
|
||
|
|
creates in DCM can be mapped to the user profile.</span> Use the EIM registry
|
||
|
|
definition name for the local <span class="uicontrol"><span class="keyword">i5/OS</span></span> user
|
||
|
|
registry that you specified in the <span class="uicontrol">EIM Configuration</span> wizard.</li>
|
||
|
|
</ol>
|
||
|
|
<div class="section"><p>After you complete the necessary EIM configuration tasks, you must
|
||
|
|
use the <span class="uicontrol">Manage LDAP Location</span> task to configure Digital
|
||
|
|
Certificate Manager (DCM) to store user certificates in a Lightweight Directory
|
||
|
|
Access Protocol (LDAP) location instead of with a user profile. When you configure
|
||
|
|
EIM and DCM to work together, the <span class="uicontrol">Create Certificate</span> task
|
||
|
|
for user certificates and the <span class="uicontrol">Assign a user certificate</span> task
|
||
|
|
process certificates for EIM usage rather than assigning the certificate to
|
||
|
|
a user profile. DCM stores the certificate in the configured LDAP directory
|
||
|
|
and uses the certificate's distinguished name (DN) information to create a
|
||
|
|
source association for the appropriate EIM identifier. This allows operating
|
||
|
|
systems and applications to use the certificate as the source of an EIM mapping
|
||
|
|
lookup operation to map from the certificate to a target user identity associated
|
||
|
|
with the same EIM identifier.</p>
|
||
|
|
<p>Additionally, when you configure EIM and
|
||
|
|
DCM to work together you can use DCM to check user certificate expiration
|
||
|
|
at the enterprise level rather than just at the system level.</p>
