<pre>public final class <span class="typeNameLabel">AuthenticationPermission</span>
extends <a href="http://docs.oracle.com/javase/6/docs/api/java/security/Permission.html?is-external=true" title="class or interface in java.security">Permission</a></pre>
<div class="block">Represents permission to use the private credentials of subjects for the
purpose of authenticating as any subset of the local principals specified
in the target name, during secure remote calls with any peer that
authenticates as at least the set of peer principals specified in the
target name. In general, security providers check for this permission
instead of checking for
<a href="http://docs.oracle.com/javase/6/docs/api/javax/security/auth/PrivateCredentialPermission.html?is-external=true" title="class or interface in javax.security.auth"><code>PrivateCredentialPermission</code></a>. This
permission does not need to be granted for anonymous communication;
it only needs to be granted if an entity needs to authenticate itself.
<p>
An instance of this class contains a name (also referred to as a "target
name") and a set of actions. The target name specifies both the maximum
set of principals that an entity can authenticate as, and the minimum
set of principals that the peer must authenticate as. The actions specify
whether the permission is granted for making outbound remote calls with or
without delegation, listening for incoming remote calls, receiving
incoming remote calls, or some combination.
<p>
The syntax of the target name is either:
<pre><i>LocalPrincipals</i></pre>
or:
<pre><i>LocalPrincipals</i> <code>peer</code> <i>PeerPrincipals</i></pre>
where <i>LocalPrincipals</i> specifies the maximum set of principals that
an entity can authenticate as (that is, the entity can authenticate as any
subset of these principals), and <i>PeerPrincipals</i> specifies the
minimum set of principals that the peer must authenticate as (that is,
the peer must authenticate as at least all of these principals). If the
first syntactic form is used, the peer can authenticate as anyone (and can
be anonymous). The syntax of both <i>LocalPrincipals</i> and
<i>PeerPrincipals</i> is:
<pre><i>PrincipalClass</i> "<i>PrincipalName</i>" ...</pre>
That is, alternating principal classes and principal names, separated by
spaces, with each principal name surrounded by quotes. The order in which
principals are specified does not matter, but both class names and
principal names are case sensitive. For <i>LocalPrincipals</i>, in any
given principal specification, a wildcard value of "*" can be used for
both <i>PrincipalClass</i> and <i>PrincipalName</i> or for just
<i>PrincipalName</i>, but it is illegal to use a wildcard value for just
<i>PrincipalClass</i>. Explicit wildcard values cannot be used in
<i>PeerPrincipals</i>; only complete wildcarding of the peer is supported,
and is expressed by using the first syntactic form instead.
<p>
The syntax of the actions is a comma-separated list of any of the following
(case-insensitive) action names: <code>listen</code>, <code>accept</code>,
<code>connect</code>, <code>delegate</code>. The <code>listen</code> action
grants permission to authenticate as the server when listening for
incoming remote calls; in this case, the peer principals are ignored
(because it is assumed that in general servers authenticate themselves
before clients do). The <code>accept</code> action grants permission to
receive authenticated incoming remote calls; in this case, the entity has
authenticated as the server, and the peer has authenticated as the client.
If the <code>accept</code> action is specified, the <code>listen</code>
action is implied and need not be specified explicitly. The
<code>connect</code> action grants permission to authenticate when
making outgoing remote calls; in this case, the entity authenticates as
the client, and the peer authenticates as the server. The
<code>delegate</code> action grants permission to authenticate with
(or without) delegation when making outgoing remote calls. If the
<code>delegate</code> action is specified, the <code>connect</code>
action is implied and need not be specified explicitly.
<p>
A principal <code>p</code> matches <i>LocalPrincipals</i> if
<i>LocalPrincipals</i> has any of the following principal specifications:
<ul>
<li>"*" for both <i>PrincipalClass</i> and <i>PrincipalName</i>
<li>a <i>PrincipalClass</i> equal to the value of
<code>p.getClass().getName()</code> and a <i>PrincipalName</i> equal to "*"
<li>a <i>PrincipalClass</i> equal to the value of
<code>p.getClass().getName()</code> and a <i>PrincipalName</i> equal to
the value of <code>p.getName()</code>
</ul>
A principal <code>p</code> matches <i>PeerPrincipals</i> if
<i>PeerPrincipals</i> has a <i>PrincipalClass</i> equal to the value of
<code>p.getClass().getName()</code> and a <i>PrincipalName</i> equal to
the value of <code>p.getName()</code>.
<p>
Some example policy file permissions:
<pre>
// client authenticate as jack, with or without delegation, to any server
permission net.jini.security.AuthenticationPermission
"javax.security.auth.x500.X500Principal \"CN=jack\"", "delegate";
// client authenticate as joe and/or sue, without delegation, to any server
permission net.jini.security.AuthenticationPermission
"javax.security.auth.x500.X500Principal \"CN=joe\" javax.security.auth.x500.X500Principal \"CN=sue\"", "connect";
