  I'm trying to set CAS up with LDAP for authentication.
I'm receiving this error when I access CAS:

CAS is Unavailable

There was a fatal error initializing the CAS application context. This is almost always because of an error in the Spring bean configuration files. Are the files valid XML? Do the beans they refer to all exist?

Before placing CAS in production, you should change this page to present a UI appropriate for the case where the CAS web application is fundamentally broken. Perhaps "Sorry, CAS is currently unavailable." with some links to your user support information.

The Throwable encountered at context listener initialization was:

org.springframework.beans.factory.CannotLoadBeanClassException: Error loading class [org.jasig.cas.adaptors.ldap.util.AuthenticatedLdapContextSource] for bean with name 'contextSource' defined in ServletContext resource [/WEB-INF/deployerConfigContext.xml]: problem with class file or dependent class; nested exception is java.lang.NoClassDefFoundError: org/springframework/ldap/support/LdapContextSource

The Throwable encountered at dispatcher servlet initialization was:

org.springframework.beans.factory.CannotLoadBeanClassException: Error loading class [org.jasig.cas.adaptors.ldap.util.AuthenticatedLdapContextSource] for bean with name 'contextSource' defined in ServletContext resource [/WEB-INF/deployerConfigContext.xml]: problem with class file or dependent class; nested exception is java.lang.NoClassDefFoundError: org/springframework/ldap/support/LdapContextSource


The deployerConfigContext.xml looks loke this:

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE beans PUBLIC  "-//SPRING//DTD BEAN//EN" "http://www.springframework.org/dtd/spring-beans.dtd">
<!--
    | deployerConfigContext.xml centralizes into one file some of the declarative configuration that
    | all CAS deployers will need to modify.
    |
    | This file declares some of the Spring-managed JavaBeans that make up a CAS deployment.  
    | The beans declared in this file are instantiated at context initialization time by the Spring 
    | ContextLoaderListener declared in web.xml.  It finds this file because this
    | file is among those declared in the context parameter "contextConfigLocation".
    |
    | By far the most com! mon change you will need to make in this file is to change the last bean
    | declaration to replace the default SimpleTestUsernamePasswordAuthenticationHandler with
    | one implementing your approach for authenticating usernames and passwords.
    +-->

    <!--
        | This bean declares our AuthenticationManager.  The CentralAuthenticationService service bean
        | declared in applicationContext.xml picks up this AuthenticationManager by reference to its id, 
        | "authenticationManager".  Most deployers will be able to use the default AuthenticationManager
        | implementation and so do not need to change the class of this bean.  We include the whole
   !     | AuthenticationManager here in the userConfigCont ext.xml so that you can see the things you will

            | supports the presented credentials.
            |
           ! | AuthenticationManagerImpl uses these resolvers for two purposes.  First, it uses them to identify the Principal
            | attempting to authenticate to CAS /login .  In the default configuration, it is the DefaultCredentialsToPrincipalResolver

            | using.
            |
            | Second, AuthenticationManagerImpl uses these resolvers to identify a service requesting a proxy! granting ticket. 
        &n bsp;   | In the default configuration, it is the HttpBasedServiceCredentialsToPrincipalResolver that serves this purpose.

Please help me figure out what's wrong.

Thank you
