Configuring Single Sign-On Support
3. For each web application that you need to operate under the single sign-on
support environment, define appropriate <security-constraint> and
<login-config> elements in the web application’s web.xml. The <security-
constraint> elements identify portions of the application's URI space that are
required for user authentication, and the <login-config> element is used if this
application is the first one accessed by the user that requires the user to log in.
There are no restrictions on different web applications utilizing different
authentication methods.
Example 3-31. Configuring Single Sign-On Support
<Host name="localhost" ...>
...
<Valve className="org.apache.catalina.authenticator.SingleSignOn"
debug="0"/>

</Host>
