LDAP 3.0 Error When setting up new configuration

While setting up the new LDAP 3.0 Module in a 4.2.1 mendix app, when I hit the 'Read LDAP' button, I get the following error message (in a red mx error popup): "could not initialize class, org.springframework.ldapcore.LdapTemplate" I have entered and saved the following details: - Server address - LDAP root directory - Is Active Directory (tm) server - Username - Password - User mapping Does someone have an idea what is going wrong? I do not get an error in the mendix console...

Forgot to set 'Emulate Cloud Security' to false. I'm always forgetting it is set to yes by default these days...
