Hello everybody.
Eric, thanks for the rapide response. I took the $PATH of least
resistance, corrected Technique #1, and now it WORKS !
httpd.conf:
RewriteEngine on
RewriteRule .* - [E=SMUSER:%{LA-U:REMOTE_USER}]
Result (setenv.pl):
...
SMUSER="<my-LDAP-userid :-) >"
...
Thanks again, Dave
PS: I had no luck with setenvif but I'm more than happy with the
RewriteRule.

I think the $ is extraneous and causing problems. Another potential
problem -- See the "lookahead" feature to figure out REMOTE_USER when
your RewriteRules are running in a phase before REMOTE_USER is set!
You may be able to wrap your rules in <Directory>, which makes the
Rewrite occur a little bit later, and might let some rules like this
work better.
Finally, why do you want to set the environment variable in a request
header? Is this just some debug you added along the way, or your
ultimate goal?
Question 1: The syntax is incredibly cryptic. Where might I look to help me
understand the %, e, {} etc.
The variable syntax for RequestHeader is defined in a table at the
bottom of the Header directive:
http://httpd.apache.org/docs/current/mod/mod_headers.html#header
The syntax for mod_rewrite is midway down in the doc for RewriteRule:
http://httpd.apache.org/docs/current/mod/mod_rewrite.html#rewriterule
Mind you, it works for simple text:
RewriteRule .* - [E=SMUSER:test]
Result: SMUSER="test"
2. Technique 2: setenv DAVESETENV "text"
----------------------------------------------
Result: DAVESETENV="text"
But, I've read that this is only a static string.

setenvif is a bit more flexible:
