<h1 class="topictitle1">Creating GSSContext</h1>
|
|
<div><p>IBM<sup>®</sup> JGSS
|
|
supports two methods provided by GSSManager for creating a context.</p>
|
|
<p>These methods are:</p>
|
|
<ul><li> A method used by the context initiator</li>
|
|
<li> A method used by the acceptor</li>
|
|
</ul>
|
|
<div class="note"><span class="notetitle">Note:</span> GSSManager provides a third method for creating a context that involves
|
|
recreating previously exported contexts. However, because IBM JGSS Kerberos
|
|
V5 mechanism does not support the use of exported contexts, IBM JGSS does
|
|
not support this method.</div>
|
|
<p>Your application cannot use an initiator context for context acceptance,
|
|
nor can it use an acceptor context for context initiation. Both supported
|
|
methods for creating a context require a credential as input. When the value
|
|
of the credential is null, JGSS uses the default credential.</p>
|
|
<p><strong>Examples: Using GSSContext</strong></p>
|
|
<p>The following example creates a context with which the principal (foo)
|
|
can initiate a context with the peer (superSecureServer) on the host (securityCentral).
|
|
The example specifies the peer as superSecureServer@securityCentral. The created
|
|
context is valid for the default period:</p>
|
|
<pre>GSSName serverName = manager.createName("superSecureServer@securityCentral",
|
|
GSSName.NT_HOSTBASED_SERVICE, krb5Mech);
|
|
GSSContext fooContext = manager.createContext(serverName, krb5Mech, fooCreds,
|
|
GSSCredential.DEFAULT_LIFETIME);</pre>
|
|
<p>The following example creates a context for superSecureServer in order
|
|
to accept contexts initiated by any peer:</p>
|
|
<pre>GSSContext serverAcceptorContext = manager.createContext(serverCreds);</pre>
|
|
<p>Note that your application can create and simultaneously use both types
|
|
of contexts.</p>
