/**
 * 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 JDK1.4
