<h1 class="topictitle1">Create and join a new local domain</h1>
<div><p>This information explains how to create a new Enterprise Identity
Mapping (EIM) domain for your enterprise and to configure the local directory
server to be the EIM domain controller for the new domain.</p>
<div class="section"><p>When you use the EIM Configuration wizard to create and join a
new domain, you can choose to configure the EIM domain controller on the local
system as part of creating your EIM configuration. If necessary, the EIM Configuration
wizard ensures that you provide basic configuration information for the directory
server. Also, if Kerberos is not currently configured on the iSeries™ server,
the wizard prompts you to launch the Network Authentication Service Configuration
wizard.</p>
<div class="p">When you complete the EIM Configuration wizard, you can accomplish
these tasks: <ul><li>Create a new EIM domain.</li>
<li>Configure the local directory server to act as the EIM domain controller.</li>
<li>Configure network authentication service for the system.</li>
<li>Create EIM registry definitions for the local i5/OS™ registry and the Kerberos registry.</li>
<li>Configure the system to participate in the new EIM domain.</li>
</ul>
</div>
<p>To configure your system to create and join a new EIM domain,
you must have all the following special authorities: </p>
<ul><li>Security administrator (*SECADM).</li>
<li>All object (*ALLOBJ). </li>
<li>System configuration (*IOSYSCFG). </li>
</ul>
<p>To use the EIM Configuration wizard to create and join a new local
domain, complete these steps:</p>
</div>
<ol><li class="stepexpand"><span>In iSeries Navigator,
select the system for which you want to configure EIM and expand <span class="uicontrol">Network
&gt; Enterprise Identity Mapping</span>.</span></li>
<li class="stepexpand"><span>Right-click <span class="uicontrol">Configuration</span> and select <span class="uicontrol">Configure...</span> to
start the EIM Configuration wizard. </span> <div class="note"><span class="notetitle">Note:</span> This option is labeled <span class="uicontrol">Reconfigure...</span> if
EIM has been previously configured on the system.</div>
</li>
<li class="stepexpand"><span>On the <span class="uicontrol">Welcome</span> page of the wizard, select <span class="uicontrol">Create
and join a new domain</span>, and click <span class="uicontrol">Next</span>.</span></li>
<li class="stepexpand"><span>On the <span class="uicontrol">Specify EIM Domain Location</span> page,
select <span class="uicontrol">On the local Directory server</span> and click <span class="uicontrol">Next</span>.</span> <div class="note"><span class="notetitle">Note:</span> This option configures the local directory server to act as the
EIM domain controller. Because this directory server stores all EIM data for
the domain, it must be active and remain active to support EIM mapping lookups
and other operations.</div>
<p>If network authentication service is not currently
configured on the iSeries server, or additional network authentication
configuration information is needed to configure a single signon environment,
the <span class="uicontrol">Network Authentication Services Configuration</span> page
displays. This page allows you start the Network Authentication Service Configuration
wizard so that you can <a href="../rzakh/rzakhconfig.htm">configure network authentication service</a>. Or, you can
configure Network Authentication Service at a later time by using the configuration
wizard for this service through iSeries Navigator. When you complete
network authentication service configuration, the EIM Configuration wizard
continues.</p>
</li>
<li class="stepexpand"><span>To configure network authentication service, complete these steps:</span><ol type="a"><li class="substepexpand"><span>On the <span class="uicontrol">Configure Network Authentication Service</span> page,
select <span class="uicontrol">Yes</span> to start the Network Authentication Service
Configuration wizard. With this wizard, you can configure several i5/OS interfaces
and services to participate in a Kerberos realm as well as configure a single
signon environment that uses both EIM and network authentication service.</span></li>
<li class="substepexpand"><span>On the <span class="uicontrol">Specify Realm Information</span> page,
specify the name of the default realm in the <span class="uicontrol">Default realm</span> field.
If you are using Microsoft<sup>®</sup> Active Directory for Kerberos authentication,
select <span class="uicontrol">Microsoft Active Directory is used for Kerberos authentication</span>,
and click <span class="uicontrol">Next</span>.</span></li>
<li class="substepexpand"><span>On the <span class="uicontrol">Specify KDC Information</span> page,
specify the fully qualified name of the Kerberos server for this realm in

and click <span class="uicontrol">Next</span>.</span></li>
<li class="substepexpand"><span>On the <span class="uicontrol">Specify Password Server Information</span> page,
select either <span class="uicontrol">Yes</span> or <span class="uicontrol">No</span> for
setting up a password server. The password server allows principals to change
passwords on the Kerberos server. If you select <span class="uicontrol">Yes</span>,
enter the password server name in the <span class="uicontrol">Password server</span> field.
In the <span class="uicontrol">Port</span> field, accept the default value of <samp class="codeph">464</samp>,
and click Next.</span></li>
<li class="substepexpand"><span>On the <span class="uicontrol">Select Keytab Entries</span> page, select <span class="uicontrol">i5/OS
Kerberos Authentication</span>, and cllick <span class="uicontrol">Next</span>.</span> <div class="note"><span class="notetitle">Note:</span> In addition you can also create keytab entries for the IBM<sup>®</sup> Directory
Server for iSeries (LDAP), iSeries NetServer™,
and iSeries HTTP
server if you want these services to use Kerberos authentication. You may
need to perform additional configuration for these services before they can
use Kerberos authentication.</div>
</li>
<li class="substepexpand"><span>On the <span class="uicontrol">Create i5/OS Keytab Entry</span> page,
enter and confirm a password, and click <span class="uicontrol">Next</span>. This
is the same password you will use when you add the i5/OS principals to the Kerberos server.</span></li>
<li class="substepexpand"><strong>Optional: </strong><span>On the <span class="uicontrol">Create Batch File</span> page,
select <span class="uicontrol">Yes</span>, specify the following information, and

Click <span class="uicontrol">Browse</span> to locate the appropriate directory path,
or edit the path in the <span class="uicontrol">Batch file</span> field.</li>
<li>In the <span class="uicontrol">Include password</span> field, select <span class="uicontrol">Yes</span>.
This ensures that all passwords associated with the i5/OS service principal are included in
the batch file. It is important to note that passwords are displayed in clear
text and can be read by anyone with read access to the batch file. Therefore,
it is essential that you delete the batch file from the Kerberos server and
from the PC immediately after you use it. If you do not include the password,
you will be prompted for the password when you run the batch file.<div class="note"><span class="notetitle">Note:</span> You
can also manually add the service principals that are generated by the wizard
to Microsoft Active
Directory. To learn how to do this, see <a href="../rzakh/rzakhdefineiseries.htm">Add i5/OS principals to the Kerberos server</a></div>

or <span class="uicontrol">Kerberos principal and password</span>. Which user types
you can select vary based on the current system configuration. For example,
if Network Authentication Service is not configured for the system, then Kerberos
user types may not be available for selection. The user type that you select
determines the other information that you must provide to complete the page
as follows: <div class="note"><span class="notetitle">Note:</span> You must specify a user that is currently defined in the
directory server which is hosting the EIM domain controller. The user that
you specify must have privileges to perform mapping lookup and registry administration
for the local user registry at a minimum. If the user that you specify does
not have these privileges, then certain operating system functions related
to the use of single signon and the deletion of user profiles may fail.<p>If
you have not configured the directory server prior to running this wizard,
the only user type you can select is <span class="uicontrol">Distinguished name and password</span> and
the only distinguished name you can specify is the LDAP administrator's DN.</p>

<li class="stepexpand"><span>If the only EIM user you have defined is the DN for the LDAP administrator,
then your EIM user has a high level of authority to all data on the directory
server. Therefore, you might consider creating one or more DNs as additional
users that have more appropriate and limited <a href="../rzalv/rzalveservereimauths.htm">access control</a> for EIM data. </span> To learn more
about creating DNs for the directory server, see <a href="../rzahy/rzahyunderdn.htm">Distinguished names</a> in the IBM Directory Server for iSeries (LDAP)
topic. The number of additional EIM users that you define depends on your
security policy's emphasis on the separation of security duties and responsibilities.
Typically, you might create at least the two following types of DNs:<ul><li><strong>A user that has EIM administrator access control</strong><p>This EIM administrator
DN provides the appropriate level of authority for an administrator who is
responsible for managing the EIM domain. This EIM administrator DN could
be used to connect to the domain controller when managing all aspects of the
EIM domain by means of iSeries Navigator.</p>
</li>
<li><strong>At least one user that has all of the following access controls</strong>:<ul><li>Identifier administrator</li>
<li>Registry administrator</li>
<li>EIM mapping operations</li>
</ul>
This user provides the appropriate level of access control required for
the system user that performs EIM operations on behalf of the operating system.</li>
</ul>
<div class="note"><span class="notetitle">Note:</span> To use this new DN for the system user instead of the LDAP administrator
DN, you must change the EIM configuration properties for the iSeries server.
See <a href="../rzalv/rzalvmanageconfigprops.htm">Manage
EIM configuration properties</a> to learn how to change the system user
DN.</div>
</li>
</ol>
<div class="section"><p>Additionally, you might want to use Secure Sockets Layer (SSL)
or Transport Layer Security (TLS) to <a href="rzalvseccon.htm#rzalvseccon">configure
a secure connection to the EIM domain controller</a> to protect the transmission
of EIM data. If you enable SSL for the directory server, you must update EIM
configuration properties to specify that the iSeries server uses a secure SSL connection.
Also, you must update the properties for the domain to specify that EIM uses
SSL connections for managing the domain through iSeries Navigator.</p>
<div class="note"><span class="notetitle">Note:</span> You might
need to perform additional tasks if you created a basic network authentication
