ldap error

[Sumiya Sakoda]

Hello.
I am trying to ldap authentication with CAS, but it does'nt work.

First, I get three archives.
* cas-server-3.0.5.tar.gz
* ldaptemplate-bin-1.0.2.zip
* commons-lang-2.1.tar.gz

Next, I have done the action to install as follows.
1. uncommpress archives.
2. put cas-server-ldap-3.0.5.jar, ldaptemplate-1.0.2.jar,
commons-lang-2.1.jar in ${project.home}/localPlugins/lib.
3. make war file in ${project.home} with ant
$ ant war
4. deploy cas.war by Tomcat 5.5 Web application manager.
5. try to test SimpleTestUsernamePasswordAuthenticationHandler with
both of same username and password on http://localhost:8080/cardweb.
it works.

Then, I refer to follwing url to use ldap.
http://www.ja-sig.org/products/cas/server/ldapauthhandler/index.html 

I customized deployerConfigContext.xml like this

<!-- begin -->
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE beans PUBLIC  "-//SPRING//DTD BEAN//EN" "http://www.springframework.org/dtd/spring-beans.dtd">

      </list>
    </property>
  </bean>
</beans>
<!-- end -->

I try to login, but I can't. it says

"""
CAS is Unavailable

A general exception occurred while trying to access CAS. Please notify your system administrator.
"""

I have no idea for the reason. but CAS Generic Handler works well with
this genericHandler.xml

<!-- begin -->
<?xml version="1.0"?>

<authentication debug="off">
  <handler>
    <classname>org.esupportail.cas.server.handlers.ldap.FastBindLdapHandler</classname>
    <config>
      <filter>uid=%u,ou=Users,dc=toyoake,dc=or,dc=jp</filter>
      <server>
        <url>ldap://localhost</url>
      </server>
    </config>
  </handler>
</authentication>
<!-- end -->

Does anyone help me ?
