<div><p>This information explains the process of authentication and the
|
||
|
|
role that it plays in a single signon solution.</p>
|
||
|
|
<p>Authentication is the process in which an individual indicates who he is
|
||
|
|
and then proves it, typically based on a user name and password. The process
|
||
|
|
of authentication is different from the process of <a href="rzamzauthorization.htm">authorization</a>,
|
||
|
|
in which an entity or a person is granted or denied access to a network or
|
||
|
|
system resource.</p>
|
||
|
|
<p>A single signon environment streamlines the process and management of authentication
|
||
|
|
for users and administrators. Because of the way single signon is implemented
|
||
|
|
on your system, not only do users need to supply fewer IDs and passwords but,
|
||
|
|
if you choose to, they do not even need to have a <span class="keyword">i5/OS™</span> passwords.
|
||
|
|
Administrators need to troubleshoot identity and password problems less often
|
||
|
|
because users need to know fewer identities and passwords to access the systems
|
||
|
|
that they use.</p>
|
||
|
|
<div class="p">Interfaces that are enabled for single signon require the use of Kerberos
|
||
|
|
as the authentication method. <a href="../rzakh/rzakh000.htm">Network authentication service</a> is the <span class="keyword">i5/OS</span> implementation
|
||
|
|
of the Kerberos authentication function. Network authentication service provides
|
||
|
|
a distributed authentication mechanism through the use of a Kerberos server,
|
||
|
|
also called a key distribution center (KDC), which creates service tickets
|
||
|
|
that are used to authenticate the user (a <span class="uicontrol">principal</span> in
|
||
|
|
Kerberos terms) to some service on the network. The ticket provides proof
|
||
|
|
of the principal's identity to other services that the principal requests
|
||
|
|
in the network.<div class="note"><span class="notetitle">Note:</span> If you are an application developer, it is possible to
|
||
|
|
make use of other types of authentication methods as you enable your applications
|
||
|
|
to work in a single signon environment. For example, you can create applications
|
||
|
|
that use an authentication method, such as digital certificates, in conjunction
|
||
|
|
with EIM APIs to enable your application to participate in a single signon
|
||
|
|
environment.</div>
