## Package javax.security.auth.kerberos Description

This package contains utility classes related to the Kerberos network authentication protocol. They do not provide much Kerberos support themselves.

The Kerberos network authentication protocol is defined in RFC 1510. The Java 2 platform contains support for the client side of Kerberos via the `org.ietf.jgss` package. There might also be a login module that implements `LoginModule` to authenticate Kerberos principals.

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 <java-home>/lib/security. If you place this file elsewhere, you can indicate that location via the system property java.security.krb5.conf.

Since:
  JDK1.4
