Error when using ldap-server tag

Hi All,

I am trying to use LDAP authentication but whenever I include the ldap-server tag or the ldap-authentication-provider tag I get an error (below) when deploying to Tomcat. If I don't use either of these tags spring security works fine. Anyone have any suggestions? My applicationContext-security configuration is also included below.

Thanks,

Ed
