1. Create a web application named myweb in your Tomcat Web server by adding the following
code to the file $CATALINA_HOME/conf/server.xml:
TIP: To apply the following <Realm/> configuration to all of your virtual machines, insert
it between the <Engine/> tags. You can also apply it to the scope of a virtual host by
inserting it between the <Host/> tags because this relies on the content being protected.
<Realm className="org.apache.catalina.realm.JNDIRealm"
connectionURL="ldap://YOUR_CDS_SERVER_IP:389"
connectionName="cn=Manager,dc=example,dc=com"
connectionPassword="secret"
userPattern="uid={0},ou=people,dc=osm,dc=example,dc=com"
roleBase="ou=groups,dc=osm,dc=example,dc=com"
roleName="cn"
roleSearch="(uniqueMember={0})"
/>
2. Next, avoid a conflict by commenting out the Tomcat default authentication setting lines as
follows:
<!--
<Realm className="org.apache.catalina.realm.UserDatabaseRealm"
resourceName="UserDatabase"/>
-->
3. Edit the $CATALINA_HOME/webapps/myweb/WEB-INF/web.xml application file and add
the following lines:
<?xml version="1.0" encoding="ISO-8859-1"?>
<web-app xmlns="http://java.sun.com/xml/ns/j2ee"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

4. Create a file named, $CATALINA_HOME/webapps/myweb/index.html, and add the
