My personal preference would be to stay within the flow control layer,
and implement your LDAP query as a Javascript function or a Java method
that returns a boolean. I think the LDAPTransformer is probably a good
tool for getting LDAP data into a pipeline for publishing purposes, but
IMO not the right tool for your job.

If you use an existing Java LDAP library then the code you have to write
to perform the query should be minimal.

Just my 2 cents.
