<p>The <strong>ldap_modrdn()</strong> function is used to perform an LDAP
modify relative distinguished name (RDN) operation. The function takes the
distinguished name of the entry whose RDN is to be changed, and <em>
newrdn</em>, the new RDN to give the entry. The <em>deleteoldrdn</em> parameter
is used as a boolean value to indicate whether the old RDN values should be
deleted from the entry or not.</p>
<p><strong>ldap_modrdn()</strong> performs an asynchronous request. The result
of the operation can be obtained by a subsequent call to <a href=
"ldap_result.htm">ldap_result()</a>.</p>
<p>In LDAP V2, the <strong>ldap_modrdn()</strong> and <a href=
"ldap_modrdn_s.htm">ldap_modrdn_s()</a> APIs were used to change the name of an
LDAP entry. They could only be used to change the least significant component
of a name (the RDN or relative distinguished name). LDAP V3 provides the Modify
DN protocol operation that allows more general name change access. The <a href=
"ldap_rename.htm">ldap_rename()</a> and <a href="ldap_rename_s.htm">
ldap_rename_s()</a> routines are used to change the name of an entry, and the
use of the <strong>ldap_modrdn()</strong> and <a href="ldap_modrdn_s.htm">
ldap_modrdn_s()</a> routines are deprecated.</p>
<br>
<h3>Authorities and Locks</h3>
<p>No i5/OS authority is required. All authority checking is done by the LDAP
server.</p>
<br>
<br>
<h3>Parameters</h3>
<dl>
<dt><em>ld</em></dt>
<dd>(Input) Specifies the LDAP pointer returned by a previous call to <a href=
"ldap_init.htm">ldap_init()</a>, <a href="ldap_ssl_init.htm">
ldap_ssl_init()</a>, or <a href="ldap_open.htm">ldap_open()</a>.<br>
<br>
</dd>
<dt><em>dn</em></dt>
<dd>(Input) Specifies the DN of the entry whose RDN is to be changed.<br>
<br>
</dd>
<dt><em>newrdn</em></dt>
<dd>(Input) Specifies the new RDN to be given to the entry.<br>
<br>
</dd>
<dt><em>deleteoldrdn</em></dt>
<dd>(Input) Specifies a boolean value. When set to 1, the old RDN value is to
be deleted from the entry. When set to 0, the old RDN value should be retained
as a non-distinguished value.<br>
<br>
</dd>
</dl>
<br>
<h3>Return Value</h3>
<dl>
<dt><strong>Message ID of the Operation Initiated</strong></dt>
<dd>if the request was successful. A subsequent call to <a href=
"ldap_result.htm">ldap_result()</a>, can be used to obtain the result of the
modify.<br>
<br>
</dd>
<dt><strong>-1</strong></dt>
<dd>if the request was not successful.<br>
<br>
</dd>
</dl>
<br>
<h3>Error Conditions</h3>
<p>If <strong>ldap_modrdn()</strong> is not successful, <em>ld_errno</em> will
be set to indicate the error. See <a href="ldap_error_condt.htm">LDAP Client
API Error Conditions</a> for possible LDAP error code values. Use the <a href=
"ldap_get_errno.htm">ldap_get_errno()</a> function to retrieve the error
information.</p>
