/**

 * This package contains utility classes related to the Kerberos network

 * authentication protocol. 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

 * {@code java.security.krb5.realm} and {@code java.security.krb5.kdc}.

 * Both properties must be set.

 * Alternatively, the {@code java.security.krb5.conf} system property can

 * be set to the location of an MIT style {@code krb5.conf} configuration

 * file. If none of these system properties are set, the {@code krb5.conf}

 * file is searched for in an implementation-specific manner. Typically,

 * an implementation will first look for a {@code krb5.conf} file in

 * {@code <java-home>/lib/security} and failing that, in an OS-specific

 * location.<p>

 *

 * The {@code krb5.conf} file is formatted in the Windows INI file style,

 * which contains a series of relations grouped into different sections.

 * Each relation contains a key and a value, the value can be an arbitrary

 * string or a boolean value. A boolean value can be one of "true", "false",

 * "yes", or "no", case-insensitive.<p>

 *

 * @since 1.4
