Zach,
It looks to me like you have a slight error in your Spring XML
configuration here.
<bean class="org.jasig.cas.adaptors.ldap.BindLdapAuthenticationHandler">
<property name="contextSource" value="contextSource" />
</bean>
What this says is "Hey, Spring, there's a property named
"contextSource", please set it to the value "contextSource", like so:
BindLdapAuthenticationHandler handler = new
BindLdapAuthenticationHandler();
handler.setContextSource("contextSource");
This doesn't work for the reason one might expect: the
setContextSource() method takes an argument of type ContextSource, not
an argument of type String. That's what this error message is trying
to say:
"java.lang.IllegalArgumentException: Cannot convert value of type
[java.lang.String] to required type
[org.jasig.cas.adaptors.ldap.util.AuthenticatedLdapContextSource] for
property 'contextSource': no matching editors or conversion strategy
found"
You've defined a bean *named* contextSource soon following in the
configuration. This property declaration needs to *reference* that
bean.
<property name="contextSource">
<ref bean="contextSource"/>
</property>
