What system do you have?
2007/11/21, Giles Thomas <giles.thomas(a)resolversystems.com>om>:
Hi all,
I am trying to implement a single sign-on system so that users of our
site can register once and then edit our wiki and post to our phpBB
forums without having to re-register and re-login. I have the phpBB
side of it working pretty well, but I'm having problems with my
MediaWiki authentication plugin, and I was hoping someone might be able
to point me in the right direction.
By way of background, my knowledge of PHP is pretty limited - Python,
Java and C# are where my experience lies.
In order to implement the plugin, I started with Jeremiah Orem's
HttpAuth extension and switched the references to
$_SERVER['PHP_AUTH_USER'] so that they looked at the "screenName"
field
on my own user objects, which I had stored in the PHP $_SESSION global .
My problem is that the user objects are not visible from the
AutoAuthenticate hook that I've written.
My existing login page stores the ResolverUser object in the session
with this code:
function SetLoggedInUser($user)
{
session_start();
$_SESSION['resolveruser'] = $user;
}
*
*I register the AutoAuthenticate hook like this (in LocalSettings.php):
require_once("$IP/extensions/ResolverAuthPlugin.php");
$wgAuth = new ResolverAuthPlugin();
$wgHooks['AutoAuthenticate'][] = array($wgAuth,'autoAuthenticate');
In the autoAuthenticate method of ResolverAuthPlugin, I call a function
to get the user so that I can create a MediaWiki user if necessary:
function GetLoggedInUser()
{
session_start();
return $_SESSION['resolveruser'];
}
But the user I get back is null. If I go to any other page that calls
the GetLoggedInUser() function, I get the correct value back, so I know
it's there. Perhaps there's some scoping issue with session values that
I don't understand? I am also suspicious of my multiple calls to
session_start(), but they've been there for a while and haven't caused
problems before...
Any hints or tips would be much appreciated; if this is off-topic for
the list, my apologies and I'd be grateful to hear where the right place
for questions like this is.
Regards,
Giles
