<p>The <strong>eimGetAttribute()</strong> function is used to get attributes
for this EIM handle.</p>
<p>The ldap configuration file is used to retrieve information for the master
host, master port, and secure port. If the host system is not a replica then
the master information retrieved is the same as the host and port defined in
the handle.</p>
