<h1 class="topictitle1">Creating a GSSName</h1>
|
||
|
|
<div><p>GSSName represents the identity of a GSS-API principal. A GSSName
|
||
|
|
may contain many representations of the principal, one for each supported
|
||
|
|
underlying mechanism. A GSSName that contains only one name representation
|
||
|
|
is called a Mechanism Name (MN).</p>
|
||
|
|
<p>GSSManager has several overloaded methods for creating a GSSName from a
|
||
|
|
string or a contiguous array of bytes. The methods interpret the string or
|
||
|
|
byte array according to a specified name type. Typically, you use the GSSName
|
||
|
|
byte-array methods to reconstitute an exported name. The exported name
|
||
|
|
is usually a mechanism name of type GSSName.NT_EXPORT_NAME. Some of these
|
||
|
|
methods allow you to specify a security mechanism with which to create the
|
||
|
|
name.</p>
|
||
|
|
<div class="section"><h4 class="sectiontitle">Example: Using GSSName</h4><p>The following
|
||
|
|
basic code snippet shows how to use GSSName.</p>

<div class="note"><span class="notetitle">Note:</span> Specify Kerberos service

name strings as either <service> or <service@host> where <service>
|
||
|
|
is the name of the service and <host> is the hostname of the machine
|
||
|
|
on which the service runs. You can (but do not have to) use a fully qualified
|
||
|
|
hostname. When you omit the @<host> portion of the string, GSSName uses
|
||
|
|
the local hostname.</div>
