Re: [Fedora-directory-users] Class Loader



Technically the tunneling should work, but I remember having issues
with it. Even after making host file additions and making the tunnel
properly the LDAP connect was still having issues. I suggest getting
the port open otherwise you are just making it hard on yourself.
