No remote user in LOG file in CGI (HTTP Authentification)

[apache.org@xxxxxxxxxxx]

Hello,

According to my previous post on the bug track:
http://issues.apache.org/bugzilla/show_bug.cgi?id=43018

This is a script in PHP that is called by the a CGI handler in Apache. HTTP
Authentification.

In a normal Apache module environnement, a HTTP Authentification is 
called and
we can see on the log of Apache :
IP - USER - [DATETIME] "GET / HTTP/1.1" 200 SIZE "REFERER" "AGENT"

Meanwhile, in a CGI environnement, Apache call a CGI script, in my 
exemple PHP
and pass him variables.
So in order of compatibility to pass the authentification to the PHP 
script, we
have to set a .htaccess where :
RewriteEngine on
RewriteRule .* - [E=REMOTE_USER:%{HTTP:Authorization},L 
<HTTP:Authorization%7D,L>]

So with it in environnement variables we can see :
[REDIRECT_REMOTE_USER] => Basic dGl0aTp0b3Rv
[REDIRECT_STATUS] => 200
where dGl0aTp0b3Rv is corresponding to user:password titi:toto (base64)

Of course, with network analyzer, we can see that the browser send to 
the Apache
serveur in HTTP headers :
Authorization: Basic dGl0aTp0b3Rv
(our titi:toto)

In this cas, Apache log don't indicate the user :
IP - - - [DATETIME] "GET / HTTP/1.1" 200 SIZE "REFERER" "AGENT"

Ok, the use of PHP is independant of Apache log writes but if browser send
Authorization: Basic dGl0aTp0b3Rv in a module Apache or CGI Apache 
(PHP), why
Apache, that see the basic, don't write the remote_user in the log ?

In normal environnement, whithout CGI, handler ..., the browser send the 
same
request and the log indicate the USER.

According to the track response, I've replaced the %u to %<u in the 
LogFormat directive but the user authentified still no appear
in the log :
IP - - - [DATETIME] "GET / HTTP/1.1" 200 SIZE "REFERER" "AGENT"


Has anyone the same problem or a soltion ?


Thank you for any help.
