I’m doing some custom authentication written in PHP and need to set the REMOTE_USER

  • 0

I’m doing some custom authentication written in PHP and need to set the REMOTE_USER variable, and make it stick, for use in other applications on the web server.

I’m able to set the REMOTE_USER variable and display it in $_SERVER, and used apache_setenv(), but a phpinfo() call in a second page doesn’t list the variable as being set.

The web server is Apache 2 with PHP 5. Any thoughts?

Addendum: An example situation would be I authenticate a user against a database table and set the REMOTE_USER variable for them and then send them via proxy to a second server, passing REMOTE_USER along the proxy, as described here for one system:

    Don’t use $_SERVER. That variable is populated from the server hosting PHP, and isn’t something you should be messing with.

    What you’re looking for is $_SESSION.
