Using PCAnywhere with OpenLDAP

I'm trying to get PCAnywhere to use my OpenLDAP server for
authentication but I can't figure out how to set it up. When I try to
add my OpenLDAP server as a host, there are authentication options for
Microsoft, Netscape, and Novell LDAP. Which one of these (if any)
should I choose and then what else do I need to do to get it running?

Thanks for any guidance you could offer.
