<h3 id="rzahyssl-rf">Secure Sockets Layer (SSL) and Transport Layer Security (TLS) with
|
|
the Directory Server</h3>
|
|
<p>To make communications with your Directory Server more secure, Directory Server can
|
|
use Secure Sockets Layer (SSL) security and Transport Layer Security (TLS).</p>
|
|
<p>SSL is the standard for Internet security. You can use SSL to communicate
|
|
with LDAP clients, as well as with replica LDAP servers. You can use client
|
|
authentication in addition to server authentication to provide additional
|
|
security to your SSL connections. Client authentication requires that the
|
|
LDAP client present a digital certificate that confirms the client's identity
|
|
to the server before a connection is established.</p>
|
|
<p>To use SSL, you must have Digital Certificate Manager (DCM), option 34
|
|
of i5/OS, installed on your system. DCM provides an interface for you to create
|
|
and manage digital certificates and certificate stores. See the "<a href="../rzahu/rzahurazhudigitalcertmngmnt.htm">Digital Certificate Manager</a>" topic for information about digital certificates
|
|
and using DCM. For information about SSL on iSeries, see the "<a href="../rzain/rzainoverview.htm">Secure Sockets Layer (SSL)</a>" topic.</p>
|
|
<p><img src="delta.gif" alt="Start of change" />TLS is designed as a successor to SSL and uses the same cryptographic
|
|
methods but supports more cryptographic algorithms. For information about
|
|
TLS on the iSeries server, see <a href="../rzain/rzainrzaintls.htm">Supported SSL and Transport
|
|
Layer Security (TLS) protocols</a>. TLS enables the server to receive secure
|
|
and unsecure communications from the client over the default port, 389. For
|
|
secure communications the client must use the StartTLS extended operation.<img src="deltaend.gif" alt="End of change" /></p>
|
|
<p>In order for a client to use TLS:</p>
|
|
<ol type="1">
|
|
<li>The Directory Server must be configured to use TLS or SSLTLS. See <a href="rzahyess-pi.htm#rzahyess-pi">Enable SSL and Transport Layer Security on the Directory Server</a>.</li>
|
|
<li>The -Y option needs to be specified on the client command line utilities.</li></ol>
|
|
<a name="wq49"></a>
|
|
<div class="notetitle" id="wq49">Note:</div>
|
|
<div class="notebody">TLS and SSL are not interoperable. Issuing a start TLS
|
|
request (the -Y option) over an SSL port causes an operations error.</div>
|
|
<p>A client can connect to the secure port (636) using either TLS or SSL.
|
|
StartTLS is an LDAP feature that allows you to start secure communication
|
|
over an existing non-secure connection (i.e. port 389). As such, you can
|
|
only use StartTLS (or command line utility -Y option) with the standard non-secure
|
|
port (389); you cannot use StartTLS with a secure connection.</p>
