26/**
27 * This package contains utility classes related to the Kerberos network
28 * authentication protocol. They do not provide much Kerberos support
29 * themselves.<p>
30 *
31 * The Kerberos network authentication protocol is defined in
32 * <a href=http://www.ietf.org/rfc/rfc4120.txt>RFC 4120</a>. The Java
33 * platform contains support for the client side of Kerberos via the
34 * {@link org.ietf.jgss} package. There might also be
35 * a login module that implements
36 * {@link javax.security.auth.spi.LoginModule LoginModule} to authenticate
37 * Kerberos principals.<p>
38 *
39 * You can provide the name of your default realm and Key Distribution
40 * Center (KDC) host for that realm using the system properties
41 * {@code java.security.krb5.realm} and {@code java.security.krb5.kdc}.
42 * Both properties must be set.
43 * Alternatively, the {@code java.security.krb5.conf} system property can
44 * be set to the location of an MIT style {@code krb5.conf} configuration
45 * file. If none of these system properties are set, the {@code krb5.conf}
46 * file is searched for in an implementation-specific manner. Typically,
47 * an implementation will first look for a {@code krb5.conf} file in
48 * {@code <java-home>/conf/security} and failing that, in an OS-specific
49 * location.<p>
50 *
51 * The {@code krb5.conf} file is formatted in the Windows INI file style,
52 * which contains a series of relations grouped into different sections.
53 * Each relation contains a key and a value, the value can be an arbitrary
54 * string or a boolean value. A boolean value can be one of "true", "false",
55 * "yes", or "no", and values are case-insensitive.
56 *
