<div><p>Specify an LDAP server, a Domain Name System (DNS), and static
|
|
mappings to resolve host names and realm names. </p>
|
|
<div class="section"><p> With network authentication service, you can specify an LDAP
|
|
server, a Domain Name System (DNS), and static mappings that are added to
|
|
the configuration file to resolve host names and realm names. You can also
|
|
select all three of these methods to resolve host names. If you do select
|
|
all of these methods, network authentication service will check the directory
|
|
server first, the DNS entries second, and finally the static mappings to resolve
|
|
host names.</p>
|
|
<p>To change host resolution, complete the following steps:</p>
|
|
</div>
|
|
<ol><li class="stepexpand"><span>In iSeries™ Navigator,
|
|
expand <span class="menucascade"><span class="uicontrol">your iSeries server</span> > <span class="uicontrol">Security</span></span>.</span></li>
|
|
<li class="stepexpand"><span>Right-click <span class="uicontrol">Network Authentication Service</span> and
|
|
select <span class="uicontrol">Properties</span>.</span></li>
|
|
<li class="stepexpand"><span>On the <span class="uicontrol">Host Resolution</span> page, select <span class="uicontrol">Use
|
|
LDAP lookup</span>, <span class="uicontrol">Use DNS lookup</span>, or <span class="uicontrol">Use
|
|
static mappings</span>.</span></li>
|
|
<li class="stepexpand"><span>If you select <span class="uicontrol">Use LDAP lookup</span> as the host
|
|
resolution type, enter the name of the directory server and its corresponding
|
|
port. </span> For example, ldapsrv.myco.com might be a valid name for
|
|
the directory server. A valid port number can be 1-65535. The default port
|
|
for the directory server is 389. After you have indicated that you will use
|
|
an LDAP server to handle host name resolution, you must ensure that the realm
|
|
has been properly defined in the LDAP server. See <a href="rzakhdefinerealmsldap.htm#definerealmsldap">Define realms in the LDAP server</a> for
|
|
more information.</li>
|
|
<li class="stepexpand"><span>If you select <span class="uicontrol">Use DNS lookup</span> as the host
|
|
resolution type, you must have configured the DNS to map to realm names. After
|
|
you have indicated that you will use a DNS server to handle host name resolution,
|
|
you must ensure that the realm has been properly defined in the DNS. See <a href="rzakhdefinerealmsdns.htm#definerealmsdns">Define realms in the DNS database</a> for more information.</span></li>
|
|
<li class="stepexpand"><span>If you select <span class="uicontrol">Use static mappings</span> as the
|
|
host resolution type, enter the name of the realm name and its corresponding
|
|
DNS name. For example, the host name might be mypc.mycompanylan.com and the
|
|
realm name is MYCO.COM. You can also map generic host names to a specific
|
|
realm. For instance if all machines that end with myco.lan.com are part of
|
|
the MYCO.COM, you might enter <tt>myco.lan.com</tt> as the DNS name and MYCO.COM
|
|
as the realm. This creates an association between the realm name and the DNS
|
|
name in the configuration file. Click <span class="uicontrol">Add</span> to create
|
|
a static mapping between the DNS and realm name in the configuration file.</span></li>
|
|
<li class="stepexpand"><span>After you have entered the pertinent information for the selected
|
|
host resolution type, click <span class="uicontrol">OK</span>.</span></li>
