They do not provide much Kerberos support    themselves.<p>     The Kerberos network authentication protocol is defined in     <a href=http://www.ietf.org/rfc/rfc4120.txt>RFC 4120</a>. The Java    platform contains support for the client side of Kerberos via the     {@link org.ietf.jgss} package. There might also be     a login module that implements    {@link javax.security.auth.spi.LoginModule LoginModule} to authenticate     Kerberos principals.<p>     You can provide the name of your default realm and Key Distribution    Center (KDC) host for that realm using the system properties    java.security.krb5.realm and java.security.krb5.kdc. Alternatively, you     can provide an MIT style configuration file called krb5.conf in    &lt;java-home&gt;/lib/security. If you place this file elsewhere, you can    indicate that location via the system property java.security.krb5.conf.<p><!--<h2>Package Specification</h2> ##### FILL IN ANY SPECS NEEDED BY JAVA COMPATIBILITY KIT #####<ul>  <li><a href="">##### REFER TO ANY FRAMEMAKER SPECIFICATION HERE #####</a></ul> <h2>Related Documentation</h2> For overviews, tutorials, examples, guides, and tool documentation, please see:<ul>  <li><a href="">##### REFER TO NON-SPEC DOCUMENTATION HERE #####</a></ul> --> @since JDK1.4</body></html>
