<p>The <strong>eimGetAssociatedIdentifiers()</strong> function returns a list
of the identifiers. Given a registry name and user name within that user
registry, return the EIM identifier associated with it.</p>
<p>It is possible that more than one person is associated with a specific
identifier. This occurs when users share identities (and possibly passwords)
within a single instance of a user registry. While this practice is not
condoned, it does happen. This creates an ambiguous result.</p>
<p>
<img src="delta.gif" alt="Start of change">
If there are no specific associations for the registry name and user name
within that registry to an EIM identifer, then group registries will be used.
If the specified registry is a member of any group registries, then
this API will return any EIM identifiers associated with the group
registry (or registries) and the registry user name.

<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>
<li>EIM Registries Administrator</li>
<li>EIM Identifiers Administrator</li>
<li>EIM Mapping Lookup</li>
<li>EIM authority to an individual registry</li>
</ul>
<p>The list returned contains only the information that the user has authority
to access.</p>
