Working now :- )
I blame lack of coffee - I hadn't set "RewriteEngine on" before I re-wrote the
request header.
It appears it needs to be in the <location> section or your initial ntlm auth
wil fail.
<Location "/">
AuthName "Galaxy"
NTLMAuth on
NTLMAuthHelper "/usr/bin/ntlm_auth --helper-protocol=squid-2.5-ntlmssp"
NTLMBasicAuthoritative on
AuthType NTLM
require valid-user
# Take the $REMOTE_USER environment variable, trim the realm and set it as
a header in the proxy request.
RewriteEngine on
RewriteCond %{IS_SUBREQ} ^false$
RewriteCond %{LA-U:REMOTE_USER} .+\\(.+)
RewriteRule . - [E=RU:%1]
RequestHeader set REMOTE_USER %{RU}e
</Location>

If I take the rewrite out of the <location> block then NTLM auth fails as the
username is re-written and isn't a valid corporate username.
On the plus side, If I just set "RequestHeader set REMOTE_USER smithiesr" then
I get logged in as I should.

One voodoo solution that worked for me (not with NTLM, but exactly with the
same '(null)' symptom) is to take the entire "RewriteCond" part outside of the
<Location> block.
Put it in the global configuration file, after the <Location> part, but before
the proxy statement.
Also, the exact incantation that worked for me (after many many trials and
errors) is:
===
RewriteRule . - [E=RU:%{LA-U:REMOTE_USER}] RequestHeader set REMOTE_USER %{RU}e
===
It's voodoo (to me) because it probably has something to do with deep apache
internals, relating to execution order of the authentication module vs the
"mod_rewrite" parts (and the "LA-U" [Look-ahead] thing sure doesn't help to
make it clearer...).
