|
<p>The <strong>ldap_extended_operation()</strong> function is used to initiate
|
|
an asynchronous extended operation, which returns LDAP_SUCCESS if the extended
|
|
operation was successfully sent, or an LDAP error code if not. If successful,
|
|
the <strong>ldap_extended_operation()</strong> API places the message id of the
|
|
request in *<em>msgid</em>. A subsequent call to <a href="ldap_result.htm">
|
|
ldap_result()</a> can be used to obtain the result of the extended operation,
|
|
which can then be passed to <a href="ldap_parse_extended_result.htm">
|
|
ldap_parse_extended_result()</a> to obtain the Object IDentifier (OID) and data
|
|
contained in the response.</p>
|
|
|
|
<p>If the LDAP server does not support the extended operation, the server will
|
|
reject the request. To determine if the requisite extended operation is
|
|
supported by the server, get the rootDSE of the LDAP server, and check for the
|
|
supportedExtension attribute. If the values for this attribute include the OID
|
|
of your extended operation, then the server supports the extended operation. If
|
|
the supportedExtension attribute is not present in the rootDSE, then the server
|
|
is not configured to support any extended operations.</p>

<h3>Authorities and Locks</h3>
|
|
|
|
<p>No i5/OS authority is required. All authority checking is done by the LDAP
|
|
server.</p>
|
|
|
|
<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>.</dd>
|
|
|
|
<dt><em>reqoid</em></dt>
|
|
|
|
<dd>(Input) Specifies the dotted-OID text string that identifies the extended
|
|
operation to be performed by the server.</dd>
|
|
|
|
<dt><em>reqdata</em></dt>
|
|
|
|
<dd>(Input) Specifies the arbitrary data required by the extended operation (if
|
|
NULL, no data is sent to the server).</dd>
|
|
|
|
<dt><em>serverctrls</em></dt>
|
|
|
|
<dd>(Input) Specifies a list of LDAP server controls. This parameter may be set
|
|
to null. See <a href="ldap_controls.htm">LDAP Controls</a> for more information
|
|
about server controls.</dd>
|
|
|
|
<dt><em>clientctrls</em></dt>
|
|
|
|
<dd>(Input) Specifies a list of LDAP client controls. This parameter may be set
|
|
to null. See <a href="ldap_controls.htm">LDAP Controls</a> for more information
|
|
about client controls.</dd>
|
|
|
|
<dt><em>msgidp</em></dt>
|
|
|
|
<dd>(Output) This result parameter is set to the message id of the request if
|
|
the <strong>ldap_extended_operation()</strong> call succeeds.</dd>
|
|
</dl>
|
|
|
|
<br>
|
|
|
|
|
|
<h3>Return Value</h3>
|
|
|
|
<dl>
|
|
<dt><strong>LDAP_SUCCESS</strong></dt>
|
|
|
|
<dd>if the request was successful. <strong>ldap_extended_operation()</strong>
|
|
places the message id of the request in *<em>msgidp</em>. To check the result
|
|
of this operation, call <a href="ldap_result.htm">ldap_result()</a> and <a
|
|
href="ldap_parse_extended_result.htm">ldap_parse_extended_result()</a> APIs.
|
|
The server may also return an OID and result data.
|
|
<br><br>
|
|
</dd>
|
|
|
|
<dt><strong>another LDAP error code</strong></dt>
|
|
|
|
<dd>if the request was not successful.</dd>
|
|
</dl>
|
|
|
|
<br>
|
|
<br>
|
|
|
|
|
|
<h3>Error Conditions</h3>
|
|
|
|
<p>If <strong>ldap_extended_operation()</strong> is not successful, will return
|
|
a -1 instead of a valid msgid, setting the session error in the LD structure,
|
|
which can be obtained by using <a href="ldap_get_errno.htm">
|
|
ldap_get_errno()</a>.</p>
|
|
|
|
<br>
|
|
<br>
|
