It sounds like you probably have an IP filter that is blocking port 389
on the RH machine.  Depending on if you have iptables or ipchains, run
'iptables -L' (or 'ipchains -L') and look for "ldap" (or port 389) in
the output.  If it's there, then you need to remove that filter.  Look
at the iptables or ipchains docs for the proper command for that.  As a
quick test, you could of course remove all filters (run 
'service iptables stop'), but that would leave you completely exposed. 
Use at your own risk.
