[Zope] - difference between AUTHENTICATED_USER and REMOTE_USER

[Brian Hooper]

Hi there -

I was wondering, what's the difference between the DTML variables
AUTHENTICATED_USER (defined by Zope) and REMOTE_USER (listed in the
DTML guide as a CGI-defined request variable.

If AUTHENTICATED_USER is defined in a given page, it seems like
REMOTE_USER should also be defined - however, when I do something like

<!--#if AUTHENTICATED_USER-->
<!--#var REQUEST-->
<!--#/if-->

REQUEST contains a lot of stuff but not REMOTE_USER.  Am I misunderstanding
the meaning of this variable?

(the reason I want to do this is, I want to use the name of the remote user
as a parameter for a database access; there must be a good way to do this)
