A gateway that connects WWW browsers to LDAP based directories.

Web500gw expects HTTP requests from a WWW browser on a TCP port
(usually 8888).  Depending on the requested URL web500gw performs
read/search/modify/add/delete requests to the Directory and sends HTML
pages back to the browser.  Web500gw uses the LDAPv2 protocol to talk
to a Directory server. It is able to work with a Standalone LDAP
server (like UMich/OpenLDAP slapd or Netscape LDAP product) and with
an LDAP Frontend to an X.500 Directory System Agent.
