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>
