SMF 2.1 | Mediawiki 1.35.1

[sandfam]

Hello,

I'm unable to get this bridge to work, and was wondering if you could assist me. The only SMF account is the main Administrator account you setup during installation. When I edit the LocalSettings.php file with any of the Optional LocalSettings.php such as: $wgFSPAllowGroups = array(5);, or any other one, then I just get a blank, white page giving me a generic 500 Internal Error.

However, when I add just the Required LocalSettings.php portion:

wfLoadExtension('ForumSsoProvider');
$wgSMFPath = '/var/www/html';
$wgFSPSoftware = 'smf2.1';

Then the wiki no longer gives me the 500 Internal Error, but when I attempt to login - a Fatal Error occurs. So, I added the following code at the very end of LocalSettings.php in order to see a more detailed Internal Error:

error_reporting( -1 );v
ini_set( 'display_errors', 1 );

$wgShowExceptionDetails = true;
$wgShowDBErrorBacktrace = true;

Therefore, the Internal Error when attempting to login with my main Administrator account is:

[aa99e6c5e8d12031f9174bd1] /mediawiki/index.php?title=Special:UserLogin&returnto=Main+Page Error from line 136 of /var/lib/mediawiki/extensions/ForumSsoProvider/ForumSsoProvider.php: Call to a member function doRedirect() on null

Here's how my LocalSettings.php file looks. I used "XXXXX" in some spots to keep private, but don't mind sharing if need be:

All in all, I have no idea what I'm doing wrong to get this working. I'm hoping you can get me in the right direction.

I am running:
SMF 2.1 RC3
Mediawiki 1.35.1
PHP 7.3.19
Apache 2.4.38
MariaDB 10.3.27

Thank you,
Mike

Make sure you call wfLoadExtension after you defined the settings. The SSO process happens very early in the MediaWiki startup and if the settings are missing, it can cause this.

Hi again,

First off, thank you very much for your response. I apologize for not getting back to you in a timely fashion as I need additional help. I had COVID-19, and it really did me in. Anyway, I decided to downgrade SMF 2.1 RC3 to SMF 2.0.18. Everything else (Mediawiki, PHP, etc) is the same version as stated above.

So, now my LocalSettings.php is:

# This file was automatically generated by the MediaWiki 1.35.1
# installer. If you make manual changes, please keep track in case you
# need to recreate them later.
#
# See includes/DefaultSettings.php for all configurable settings
# and their default values, but don't forget to make changes in _this_
# file, not there.
#

if ( !defined( 'MEDIAWIKI' ) ) {
	exit;
}

wfLoadExtension('ForumSsoProvider');
$wgSMFPath = '/var/www/html';
$wgFSPSoftware = 'smf2.0';
$wgFSPAdminGroups = array(1, 3);

As you can see, I changed:

$wgFSPSoftware = 'smf2.1'; to $wgFSPSoftware = 'smf2.0;

And I think I followed your previous instructions by placing this earlier in the file:

wfLoadExtension('ForumSsoProvider'); $wgSMFPath = '/var/www/html'; $wgFSPSoftware = 'smf2.0'; $wgFSPAdminGroups = array(1, 3);

Now the Main page of the wiki is displaying a "Log in" link at the top, and even if I attempt to log in manually, then I get an error message saying:

Incorrect username or password entered. Please try again.

Thank you very much for your time & assistance,
Mike

[jdarwood007]

Move the wfLoadExtension to after you define the settings

$wgSMFPath = '/var/www/html';
$wgFSPSoftware = 'smf2.0';
$wgFSPAdminGroups = array(1, 3);
wfLoadExtension('ForumSsoProvider');

Mediawiki will setup the extension as soon as you call the wfLoadExtension, so the settings need to be in place first.

[ThermoMan]

If the above suggestions don't do it, you might also need
$wgFSPPath = $wgSMFPath
before you load the extension.

This ended up being the fix I needed.

[jdarwood007]

Looks like the documentation is wrong. All paths should be using $wgFS prefix as its generic.
