Installation issues

Does anyone got this extension running in a prefixed environment? I try to setup CentralAuth using only one database with 3 different prefixes for 3 different MediaWiki installations. After creating the appropriate tables using central-auth.sql, including the CentralAuth.php in LocalSettings.php, I only get errors when trying to use Special:CentralAuth or when pointing to my settings.

Do I have to adjust some other settings first or is it just not useable yet?`--Marcus Stöhr 11:53, 29 March 2008 (UTC)

CentralAuth is currently running on Wikimedia sites (including Wikinews, Wikipedia, etc) for sysops, who are being used as guinea pigs. At the moment, we have 1,472 CentralAuth users. I think Wikia uses the same system, but am not in a position to check this at the moment. Kylu 13:45, 29 March 2008 (UTC)
Yeah, I know. I've been following the postings on the mailinglist. But I'd like to test in my own environment. At the moment, I'm "sharing" users by using VIEWS over the user tables. But it's a pain in the a** if you are doing upgrades. --Marcus Stöhr 10:46, 30 March 2008 (UTC)]

Wikia has always used a shared user table, which has been in the core for years and years. Werdna 08:39, 2 April 2008 (UTC)

What does Shared Table means in this specific context? Using a VIEW or using another technique? --Marcus Stöhr

After some research, I got it working to fetch the correct database (custom one) for the CentralAuth-tables. This should be easier to modify/customize. Another issue is the usage of prefixed databases to have multiple wikis in one database, as I stated above. The plugin should load the information about the current wikisetting from the LocalSettings.php from the wiki it is executed from. Should this be classified as a bug in the bug tracker? --Marcus Stöhr 06:55, 7 April 2008 (UTC)

Note: The above (success) is contradicted the statement on Stöhr's user page, dated 11 April 2008. Anybody had success with CentralAuth when using a single db with table prefixes? --Vigilius 21:45, 28 July 2008 (UTC)

[edit] GlobalUsage-Extension needed?

I've tested the latest SVN-version of CentralAuth and got an error message:

Fatal error: Call to undefined function wfGetLB() in /home/MYDIR/extensions/CentralAuth/CentralAuthUser.php on line 27

After a little googling, I came up with the GlobalUsage-Extensions, which doesn't seem to work. The error still remains, even if I include the GlobalUsage.php BEFORE CentralAuth.php in LocalSettings.php. Does this extension, CentralAuth, only works with the latest trunk-build of MediaWiki or is there another thing I've overlooked? --Marcus Stöhr 21:38, 6 April 2008 (UTC)

Nevermind, fixed it by testing with latest trunk. --Marcus Stöhr 22:33, 6 April 2008 (UTC)

[edit] Getting the same error message on May 9th

I'm getting the same error message of

Fatal error: Call to undefined function wfgetlb() in /home/MYDIR/extensions/CentralAuth/CentralAuthUser.php on line 65

Line 65 is the 3rd line in this code:

public static function getCentralDB() {
global $wgCentralAuthDatabase;
return wfGetLB( $wgCentralAuthDatabase )->getConnection( DB_MASTER, array(),
$wgCentralAuthDatabase );
}

I was using the latest version of the CentralAuth files from the SVN downloaded on May 9th. Any ideas of what to do next? I'm using Mediawiki 1.12 and wondering if I have to upgrade to the current version of 1.13 being used on Wikipedia and related WMF sites. --72.198.213.23 17:27, 10 May 2008 (UTC)

Actual code of CentralAuth requires 1.13. Use can use the code from the 1.12 branch wich should work with 1.12. iAlex 17:34, 10 May 2008 (UTC)
Thanks for the quick reply. I'll either upgrade the wiki to Mediawiki 1.13 or will use the 1.12 version of CentralAuth. --72.198.213.23 17:40, 10 May 2008 (UTC)

[edit] Error in WikiMap.php section

I am using the May 10th version of Central Auth with the May 10th version of Mediawiki 1.13 and have installed the CentralAuth extension on this test wiki. The problem I have run into is this code in SpecialMergeAccount.php:

   function foreignUserLink( $dbname ) {
                $wiki = WikiMap::byDatabase( $dbname );
                if( !$wiki ) {
                        throw new MWException( "no wiki for $dbname" );
                }

WikiMap.php is returning NULL and this generates the "no wiki for $dbname" error message. The problematic part of WikiMap.php is the statement list( $major, $minor ) = $wgConf->siteFromDB( $dbname ) that is in the code below:

class WikiMap {
        static function byDatabase( $dbname ) {
                global $wgConf, $IP;
                static $initialiseSettingsDone = false;
 
                // This is a damn dirty hack
                ... {5 minor lines omitted)

                list( $major, $minor ) = $wgConf->siteFromDB( $dbname );
                                if( isset( $major ) ) {
                        $server = $wgConf->get( 'wgServer', $dbname, $major,
                                array( 'lang' => $minor, 'site' => $major ) );
                        $path = $wgConf->get( 'wgArticlePath', $dbname, $major,
                                array( 'lang' => $minor, 'site' => $major ) );
                        return new WikiReference( $major, $minor, $server, $path );
                } else {
                        return null;

Since my wiki set-up only consists of three sites, I presume that I can probably just comment out the call to WikiMap in SpecialMergeAccount.php and add a statement like $wiki = 'ignatian_en';. However, I tried about ten variations of what I thought $wiki should be (e.g., en, http://en.ignatianwiki.org, ignatian_en, etc.) and none worked. The current wiki site structure we have is:

I was able to add a new test account on the English wiki and it added that account (User:Workmantest4) to the English and the Global user tables. On the English user preferences page it says for Global account status: "All in order! Your account is active on 1 project site." However, when I select "Manage your global account", I get the error messages above. I'm planning to manually merge accounts (or let users merge accounts) as we have only 80 English , 25 commons, and 10 Spanish accounts. I would appreciate any advice on a value to set for $wiki (or other workarounds) to the problem I'm having in the code above.--Workman 02:51, 13 May 2008 (UTC)

The problem may be that the configuration lines were put before rather than after the require_once ("$IP/extensions/CentralAuth/CentralAuth.php"); line in LocalSettings.php. Tisane 00:26, 29 May 2010 (UTC)

[edit] changing the version # at the extension data

hey,
Maybe it would be better if the information on the working branch of CentralAuth for earlier versions of mediawiki will be noted at the main page
there it says that CentralAuth is for mediawiki 1.11+, but it's really just for 1.13.
perhaps a new download section should say where to get the earlier versions of CentralAuth

I didn't want to do it myself because I don't want to step on any toes :)
thanx, Nir.

Done. iAlex 06:44, 26 May 2008 (UTC)

[edit] Single database with prefixed tables

Is it correct, that no-one has managed to get this extension to work in a setup where multiple wikis share a single mysql database and are distinguished by prefixes?

[edit] SUL Problems

Hi,

I'm having problems with SUL, it seems that SUL isn't compatible under iSafari: I'm having to log in to the wikimedia foundation sites manually as SUL isn't automatically logging me on, could the Developer's fix this problem - it works fine under Mozilla but not the Safari browser. Dark Obsidian 18:35, 11 December 2008 (UTC)
Currently you may have to change your cookie setting from "Only from sites you navigate to" to "Always" for the cross-domain session cookies to be set; otherwise you'll only be logged in within each domain (so, all *.wikipedia.org or all *.wikimedia.org or whatever, but only whichever one(s) you've logged into). --brion 22:51, 11 December 2008 (UTC)

[edit] Cache Issue

I am now using eAccelerator as cache. Can I use CentralAuth? Unsigned post

  • onsidering eAccellerator isn't compatible with MW 1.16+, and centralauth is still in heavy development for MW-users (mostly built from code specified for the bleeding-edge wikimedia network's framework for now) it's likely you'll run into problems. You'll probably want to update to a later version of MW and use a different accelerator anyways. --Teststudent (talk) 03:37, 19 April 2012 (UTC)

[edit] Language Setting

There should be some default language setting if I go to an new language-site so the menu is in my tongue. I have some probs to read Hebrew or Hindi ;-) So if I hadn't set preferences in that interwiki I'ld prefer to have the setting from my home-wiki. Maybe there could a new option in the home-wiki "use this language for global-account". I won't write articles in foreign languages but sometimes there are interwiki-links to set. --Hagrid@de.wikipedia.org 94.249.219.9 01:26, 22 June 2009 (UTC)

I second this. It feels annoying to have to go to Special:Preferences at every new wiki and set the language to my, for example, English. 145.97.65.62 13:27, 2 February 2010 (UTC)
Surely, some settings such as gender and interface language should be copied from the home wiki instead of resorting to local defaults. But would it wise to copy all setup? Incnis Mrsi 16:28, 30 January 2012 (UTC)

[edit] Doesn't work in Internet Explorer

This extension doesn't work in Internet Exploer (I've tested on 6th and 8th versions). This extension uses special pages, that set central cookies and return images. Problem is that Internet Explorer doesn't allow to set cookies to one site, while being on another site. For example when I login on www.mediawiki.org, then I'm not logged in on en.wikipedia.org. Everything works fine on Firefox, Google Chrome and others.

[edit] Home wiki

What is it actually but gu_home_db field in a table? There were several cases in Wikimedia where a user disbanded his SUL and recreated it only to change so named "home wiki". A tool for changing gu_home_db should exist, if not accessible by the owner himself but at least by stewards. Incnis Mrsi 16:28, 30 January 2012 (UTC)

[edit] Development

[edit] Multi-wiki watchlist

In reference to bug 3525, should a multi-wiki watchlist be implemented by an enhancement to CentralAuth? I'm thinking that either a new field, identifying the wiki on which the page is located, will need to be added to the watchlist table, or a whole new table will need to be created to store the necessary data. If unified logins are in effect, it does seem to make sense to tie that in with this functionality. Thoughts? I don't think it's necessarily out of the question to have another extension that relies on this extension without being an integral part of it. It would be essentially an extension of an extension.

[edit] Step by step guide... Anyone?

This is really annoying...

I finally got CentralAuth installed, and everything works except Special:GlobalGroupMembership. It just redirects to Special:UserRights. I can only set group membership through SQL queries. Everything else works - merging, creating global groups and adding permissions.

Any ideas?

[edit] Configuring SUL

I have MW 1.18.0 and the latest revision of the extension. I host my 3 wikis as subsites of a single subdomain, with the webserver being IIS 7.5. However, when I set $wgCentralAuthCookieDomain=true;, logins do not stick, indicating a problem with cookies.Jasper Deng 06:44, 14 February 2012 (UTC)

[edit] CentralAuth wiki table name prefixes?

I've been trying to set up CentralAuth on a localhost test wiki, but I can't work out how to specify a wiki's database table name prefix. My DB name is 'mediawiki_test3' and the table name prefix is 'mw'. It was suggested to change the DB name to suffix a hyphen with the table name prefix, but it still goes looking for the same thing. ('mediawiki_test3.user') I would've expected it to look for 'mediawiki_test3.mwuser' (what I want to happen) or 'mediawiki_test3-mw.user' (not interpreting mw as the table prefix), but it just seems to ignore what I added completely. Anyone know how to do this? --Krenair (talk • contribs) 02:44, 11 March 2012 (UTC)

  • In my experience you can't use a prefix, sorry :( .Jasper Deng (talk) 06:22, 11 March 2012 (UTC)


  • Workaround: mysqldump your wiki databases. Create new databases with a common suffix. import the sql dumps into your new databases. Redirect your localsettings to point at the new databases you just created. Continue with your CentralAuth installation. Matt Thompson has a splendid walkthrough. --Teststudent (talk) 03:31, 19 April 2012 (UTC)
