Ok, I've add the security constraint. So now this is what my web.xml file looks like in regards to the single sign-on
<security-constraint>
<display-name>LoginConstraint</display-name>
<web-resource-collection>
<web-resource-name>webCal</web-resource-name>
<description/>
<url-pattern>/*</url-pattern>
<http-method>GET</http-method>
<http-method>POST</http-method>
<http-method>HEAD</http-method>
<http-method>PUT</http-method>
<http-method>OPTIONS</http-method>
<http-method>TRACE</http-method>
<http-method>DELETE</http-method>
</web-resource-collection>
</security-constraint>
<login-config>
<auth-method>BASIC</auth-method>
<realm-name>LdapRealm</realm-name>
</login-config>
It stills doesn't prompt me for a user id/password.
