<h1 class="topictitle1">Principals and credentials</h1>
|
||
|
|
<div><p>The identity under which an application engages in JGSS secure
|
||
|
|
communication with a peer is called a principal. A principal may be a real
|
||
|
|
user or an unattended service. A principal acquires security mechanism-specific
|
||
|
|
credentials as proof of identity under that mechanism.</p>
|
||
|
|
<p>For example, when using the Kerberos mechanism, a principal's credential
|
||
|
|
is in the form of a ticket-granting ticket (TGT) issued by a Kerberos key
|
||
|
|
distribution center (KDC). In a multi-mechanism environment, a GSS-API credential
|
||
|
|
can contain multiple credential elements, each element representing an underlying
|
||
|
|
mechanism credential. </p>
|
||
|
|
<p> The GSS-API standard does not prescribe how a principal acquires credentials,
|
||
|
|
and GSS-API implementations typically do not provide a means for credential
|
||
|
|
acquisition. A principal obtains credentials before using GSS-API; GSS-API
|
||
|
|
merely queries the security mechanism for credentials on behalf of the principal. </p>
|
||
|
|
<p> IBM<sup>®</sup> JGSS
|
||
|
|
includes Java™ versions of Kerberos credential management tools <a href="rzahajgssknit.htm#rzahajgssknit">com.ibm.security.krb5.internal.tools Class Kinit</a>, <a href="rzahajgssktab.htm#rzahajgssktab">com.ibm.security.krb5.internal.tools Class Ktab</a>, and <a href="rzahajgssklst.htm#klsttest">com.ibm.security.krb5.internal.tools Class Klist</a>. Additionally, IBM JGSS enhances the standard GSS-API by
|
||
|
|
providing an optional Kerberos login interface that uses JAAS. The pure Java JGSS
|
||
|
|
provider supports the optional login interface; the native iSeries™ provider
|
||
|
|
does not. For more information, see the following topics:</p>
