Hi,

	I've been having a dabble, using a perl module to handle some of our 

authentication requirements.  I have the perl auth handler working 

successfully but the username is not logged in access_log.

I have the following code in my perl module:

my $username = "test_user";
$r->user($username);

return OK;

I can see from my PHP script that the REMOTE_USER variable has been set 

successfully.

I am using the following LogFormat for access_log:

LogFormat "%h %l %u %t \"%r\" %>s %b \"%{Referer}i\" \"%{User-Agent}i\"" 

combined

Any pointers as to how I can get the username logged in access_log?

Many thanks in advance,

				Neil.

I found it necessary to do the following in my Perl auth handler as 

well as $r->user($username) (assuming Apache2 API):

$r->subprocess_env('REMOTE_USER' => $username);
$r->set_basic_credentials($username, $password);

I can't exactly recall the reasons, something about which process 

(parent or child) writes the environment variables vs. which process 

does the logging, or perhaps the order in which Apache sets variables 

and writes to the log.  Or perhaps it was just overkill on my part, 

not wanting to miss anything.  But it's working for me.
