<h3>Authorities and Locks</h3>
<dl>
<dt><em>EIM Data</em></dt>
<dd>Access to EIM data is controlled by EIM access groups. LDAP administrators
also have access to EIM data. The access groups whose members have authority to
the EIM data for this API follow:
<ul>
<li>EIM Administrator</li>
</ul>
<p>The list returned contains only the information that the user has authority
to access.</p>
</dd>
</dl>
<br>
<!-- ============================================================== -->
<!-- -->
<!-- P A R A M E T E R S -->
<!-- -->
<!-- ============================================================== -->
<h3>Parameters</h3>
<dl><!-- ============================================================== -->
<!-- ldapURL -->
<!-- ============================================================== -->
<dt><strong>ldapURL</strong>&nbsp;&nbsp;(Input)</dt>
<dd>A uniform resource locator (URL) that contains the EIM host information.
This URL has the following format:
<pre>
ldap://host:port/dn
or
ldaps://host:port/dn
</pre>
<p>where:</p>
<ul>
<li><samp>host:port</samp> is the name of the host on which the EIM domain
controller is running with an optional port number.</li>
<li><samp>dn</samp> is the distinguished name of the domain to list. If dn is
not set then all domains that are reachable from this platform are
returned.</li>
<li><samp>ldaps</samp> indicates that this host/port combination uses SSL and
TLS.</li>
</ul>
<p>Examples:</p>
<ul>
<li>ldap://systemx:389/ibm-eimDomainName=myEimDomain,o=myCompany,c=us</li>
<li>ldaps://systemy:636/</li>
</ul>
<br>
</dd>
<!-- ============================================================== -->
<!-- connectInfo -->
<!-- ============================================================== -->
<dt><strong>connectInfo</strong>&nbsp;&nbsp;(Input)</dt>
<dd>Connect information. EIM uses ldap. This parameter provides the information
required to bind to ldap.
<p>If the system is configured to connect to a secure port, EimSSLInfo is
required.</p>
<p>For EIM_SIMPLE connect type, the <samp>creds</samp> field should contain the
EimSimpleConnectInfo structure with a binddn and password. EimPasswordProtect
is used to determine the level of password protection on the ldap bind.</p>
<table cellpadding="5">
<!-- cols="40 60" -->
<tr>
<td align="left" valign="top" nowrap><em>EIM_PROTECT_NO (0)</em></td>
<td align="left" valign="top">The clear-text password is sent on the bind.</td>
</tr>
<tr>
<td align="left" valign="top" nowrap><em>EIM_PROTECT_CRAM_MD5 (1)</em></td>
<td align="left" valign="top">The protected password is sent on the bind. The
server side must support cram-md5 protocol to send the protected password.</td>
</tr>
<tr>
<td align="left" valign="top" nowrap><em>EIM_PROTECT_CRAM_MD5_OPTIONAL
(2)</em></td>
<td align="left" valign="top">The protected password is sent on the bind if the
cram-md5 protocol is supported. Otherwise, the clear-text password is
sent.</td>
</tr>
</table>
<p>For EIM_KERBEROS, the default logon credentials are used. The <samp>kerberos
creds</samp> field must be NULL.</p>
<p>For EIM_CLIENT_AUTHENTICATION, the <samp>creds</samp> field is ignored.
EimSSLInfo must be provided.</p>
<p>The structure layouts follow:</p>
<pre>
enum EimPasswordProtect {
EIM_PROTECT_NO,
EIM_PROTECT_CRAM_MD5,
EIM_PROTECT_CRAM_MD5_OPTIONAL
