getting authentication information from apache - PHP

Hello,

I'm new to php and I have am running php on apache. I already have ldap
authentication set up in apache would rather not create a separate system
for php. What would be ideal would be to get the current authenticated user
from the apache environment. At this point I'm grabbing at straws, but so
far I've tried....

$ret = apache_getenv("LDAP_USER");
echo $ret;
echo $_SERVER['PHP_AUTH_DIGEST'];
$ret = apache_getenv('PHP_AUTH_DIGEST');
echo $HTTP_SERVER_VARS['PHP_AUTH_USER'];
echo $_SERVER['REMOTE_USER'];

None of these work (all of the variables are empty). Has anyone done this??

Thanks,
Ryan

does this offer any clue?:

var_dump($_ENV, $_SERVER);

Jochem,

Hmm, not sure what I'm looking for, but from what I've read, the
REMOTE_USER should contain this informaion, mine seems to be empty.
array(30) {

If the answer you are seeking isn't available in:
<?php phpinfo();?>
run on the page where you are trying to do this, then you probably
can't get the answer you want.

Running http://php.net/ldap to re-connect and re-authenticate will
probably be fairly cheap, since LDAP is supposed to be pretty dang
fast in the first place, and whatever caching is going on for the LDAP
or OS calls behind LDAP virtually guarantees that the data you want is
in RAM.

Richard,

I looked at phpinfo() as you said, same thing...

_SERVER["REMOTE_USER"] no value

You may be right, this may not be available, but I don't want to keep
throwing a login screen in front of users for no apparent reason.

Thanks,
Ryan

Use <?php phpinfo();?> and see what *IS* there.

If what you want isn't there, then the web server didn't provide it.

If the web server didn't provide it, PHP can't be blamed for not
passing it on to you, which is *ALL* PHP does here.

So what you have is a web-server configuration issue in that case.
