Note that it's usually an anti-pattern to use an <InputDataConnector>  with the allAttributes property, because this will only work correctly if all the inputs have the same number of values. If you have result sets (e.g. from LDAP) that don't satisfy this rule, just make sure to enumerate the attributes you need. This used to be handled with an extra configuration element called <SourceAttribute> but this is no longer needed because of the new dependency syntax , and is not no longer supported in this version.
