To add an item to an array, you can use the Array.add command, passing in the array and the item. For example, you can create a JavaScript array called a like this:

// Kerberos.config ClientAuthentication { com.sun.security.auth.module.Krb5LoginModule required; }; ServerAuthentication { com.sun.security.auth.module.Krb5LoginModule required storeKey=true; };

var a = ['Item 1', 'Item 2', 'Item 3', 'Item 4'];

Figure 10-10. Adding a web reference to the native web service Click the Add Reference button to create a proxy for the web service.

Here we have specified two distinct configurations. One is for our client, and the other for a server that we will be demonstrating later in the chapter. For the client authentication, a LoginModule has been specified, and we have indicated that a login using this module is required in order to consider the authentication successful. Additional parameters may be provided (as shown in the server example, where the storeKey parameter is specified), but are not necessary for our login example. Login modules are objects that know how to talk the appropriate protocol to establish a login to a particular type of authentication server in this case a Kerberos v5 server.

NOTE Kerberos v5 is a well-respected enterprise-grade security system from MIT. Using brief exchanges of information, Kerberos can determine the identity of users without ever needing to see their password. Kerberos can also supply participants with security keys, allowing them to set up a secure channel of communication between participants with a minimal overhead. Kerberos forms the core of the authentication system in Microsoft Active Directory, and implementations exist for most platforms.

You can then add a new item to the array in Ajax JavaScript like this:

To consume the web service, you need to create a form like the one shown in Figure 10-11.

Array.add(a, 'Item 5');

A small set of modules are provided with the Java 2 SDK, and others are available either for free or commercially. For example at http://free.tagish.net/jaas/ index.jsp a set is available that will permit you to authenticate against Windows NT servers using the NTLM protocol, to authenticate using credentials stored in a text file, or to authenticate against credentials stored in a database table. The login modules in the Java 2 Standard Edition 1.4.2 SDK are contained in the com.sun.security.auth.module package. These modules include the Kerberos login module we are using, an NT login module, a Unix login module, and a Java Naming and Directory Interface (JNDI) login module. The example application to conduct a JAAS login in Kerberos follows:
