If you have errors, please check m:User talk:Otheus/Auto Login via REMOTE USER for potential solution.

Mediawiki 1.9.3 would not automatically create users until I changed setPassword and allowPasswordChange to return true.

Random blank page
This extension works perfectly with the 1.15.1 version. However, I have randomly a blank page when accessing the wiki. It happens only when this particular extension is enabled. Does anyone know how to fix that? Thanks!


 * I'm getting a similar error. SOME users get a 500 HTTP code with a blank page. It doesn't even display the error in the content, it's just the header. But this isn't for ALL users. The users who fail always fail, and the users who work always work. The error happens regardless of the browser or client being used, so it is tied to the specific users. There are no special characters or other oddities in the usernames, either (Some username capitalizations are different between what's reported as the Remote_User in phpinfo, but others aren't). No errors are logged in the PHP error log or in the wiki log when debugging is on. When I turn the extension off, no errors occur.
 * As with the previous comment, this was working fine on 1.15.1, but not on 1.18.1. I even made a 100% fresh 1.18.1 install to test with, and the same users get the same errors. I'm running the following: MediaWiki 1.18.1; PHP 5.3.10 (cgi-fcgi); MySQL 5.5.17; running IIS on a Windows XP machine --DarthZeth (talk) 17:45, 22 March 2012 (UTC)
 * Well now I feel dumb. Someone pointed out that the working users had admin access to the box. Turns out my wikiusers group didn't have read/execute permissions for the extension file for whatever reason, which was causing the error. So wrong permissions might be the cause of other 500 error/blank page problems. --DarthZeth (talk) 19:12, 22 March 2012 (UTC)

$_SERVER['REDIRECT_REMOTE_USER']
Seemed to work under 1.12pre, once I added near the top of Auth_remoteuser.php: if (!isset($_SERVER['REMOTE_USER'])) $_SERVER['REMOTE_USER'] = $_SERVER['REDIRECT_REMOTE_USER']; Jlerner 00:55, 11 December 2007 (UTC)

How does the extension know who to login?
I like this program and think it could be used very well with my website. We have a PHPBB forum and a localized login script for that on our site. What I would like is for users who login using the localized form to automatically be logged into PHPBB AND the wiki. However I am confused as to where the users login info fits into all of this? Any help will be appreciated. Thanks :P

Auto login locally?
Hi, I want to implement a Wiki internally at the company I work for and an auto-login function would be very welcome. We're using WinXP machines on DNS and would like a way to automatically pass across winodws credentials of users retrieving any details needed from AD. Is this possible and if so how would I go about doing it? Bear in mind that it is not public facing so convenience can come before security here.


 * You're looking for "Single Signon" functionality. If your web server can provide this - then this extension will use the authentication info from the server to log you into the wiki. This extension would be part of your solution... but there may be other options available.


 * Although i am using my own extension, this might be helpful. I am using LDAP to fill in the Real Name and Mail fields. Still if i want users to authenticate against NTLM (SSPI) i either have to save their password as their wiki password, to fill the user prefs or i need to have a dummy query user for calling LDAP. I am still not sure which solution is better. Passwords may change and a global user is a potential security risk.


 * This extension can be used in conjuction with Windows Authentication on IIS to allow a user access the wiki from IE on a domain local machine to be automatically authenticated with the wiki. VibroAxe 10:33, 10 December 2009 (UTC)

Apache, Windows and mod_auth_sspi
If you are using this extension with Apache on Windows, and are using mod_auth_sspi to populate REMOTE_USER, make sure that you use 1.0.3 of the module and not 1.0.4. The later version strips POSTed information. I confirme : With the 1.0.4 version of the mod_auth_sspi module i had a blanck page when i made a preview. With the 1.0.3 version, all is OK.

Cached Pages showing wrong user name
I had to turn off the server side cache to make this work properly with 1.9.3. Otherwise the user name shown at the top of the screen would sometimes be correct, and sometimes show the previous user's name, if the previous user had accessed the given page. This doesn't happen with normal user logout/login, so I assume it is to do with the AutomaticREMOTE_USER logout/login cycle. When I try to edit a page showing the wrong user name, (and the previous user hasn't tried to edit it also), the the correct user name shows on the edit page. Disabling the cache probably isn't the best solution. Any clues?

login problems with wrong REMOTE_USER
The plugin doesnt work on our system (IIS 6, Win2k3 AD, MW 1.13.2). It changed REMOTE_USER from foo_bar\username to foo bar\username. After removing foo_bar\ from username by substr($_SERVER['REMOTE_USER'],10) it works fine for us.

SunAM Authentication and authorization
I'm using the extension with Mediawiki 1.15.1 and Apache 2.2.11 with SunAM authentication.

Problems with name normalization and patch
For Mediawiki 0.13 (and above, I presume), I found I needed to do the following to allow users with underscores in their name to login:

--- remoteuser.php.orig       2009-09-14 11:41:25.000000000 -0400 +++ remoteuser.php 2009-09-14 11:39:21.000000000 -0400 @@ -229,7 +229,8 @@       return false; return isset($_SERVER['REMOTE_USER']) && -          (strtolower($username) == strtolower($_SERVER['REMOTE_USER'])); +          (strtolower($username) == +            strtolower(User::getCanonicalName($_SERVER['REMOTE_USER']))); }  /**

Implementation?
How exactly is this extension used? Are there examples?

Gotcha: WikiSysop login
If you created a WikiSysop account during Mediawiki installation, you won't be able to use that account unless it authenticates with whatever mechanism you're using to set REMOTE_USER. Keep that in mind.

OK with LDAP for me
Just because the notice on the main page is so scary... I got this going under Apache 2.2 on CentOS with the mod_authnz_ldap extension with no particular problems. The only note would be that I didn't need to worry about REMOTE_USER in my case, it was all set up already.

Active Directory SSO
Has anyone managed to get this extension working with an Active Directory SSO configuration? Specifically, retrieving HTTP headers, and automatically creating users.

I've tried setting allowPasswordChange and setPassword to true, but auto account creation doesn't seem to work.

--Enterprise user 21:15, 20 December 2010 (UTC)


 * Never mind, resolved the problem.


 * I just replaced the phrase 'REMOTE_USER' in Auth_remoteuser.php with 'HTTP_USERNAME'. User account is automatically generated now.

E-mail address as User Name
Does anyone know if using an e-mail address as a MediaWiki username is problematic? The e-mail address follows the following convention:

first.lastname@domain.com

--Enterprise user 22:04, 20 December 2010 (UTC)

Active Directory integration with Apache & Groups support
I've made some modifications to this extension that along with a bit of configuration on the Apache server allow AD users to login with full group information copied over to the auto-created MediaWiki account. Setup instructions are in the header comments of the file below. (Sorry for the full paste instead of a diff, but I haven't had any luck applying diff's to copy/paste code from wiki pages.)

Wiki Admin
When enabling this extension, the Wiki Admin account, which exists out of my LDAP authentication environment, cannont be accessed due to the absence of a login form. Is there a method by which I can access this account while the extension is active? --Enterprise user 19:51, 24 January 2011 (UTC)
 * Facing the same problem, I enabled the extension, had my account auto-created, and then disabled it. Then I logged in as sysop, granted my newly-created acount Beurocreat and sysop permissions, and re-enabled the extension. Would this work for you as well? Ethan1701 17:11, 30 January 2011 (UTC)
 * Don't see why that wouldn't work; thanks! The only issue I see with this solution is that modifications made by me to the Wiki won't appear with the username Admin; I suppose I could live with that. --Enterprise user 17:38, 31 January 2011 (UTC)

Full name (AUTHENTICATE_CN) not getting populated
I installed this extension without a hitch. Works well. However, it's not populating the Real Name field for the user. The segment of code that's meant to do it, as best I can tell, is Though I can confirm that $_SERVER["AUTHENTICATE_CN"] does in fact have a value, it's not being passed through. Might the fact it's in Hebrew affect things?

Is there any way I can remove the user in order to modify and test the code? Ethan1701 17:17, 30 January 2011 (UTC)


 * How do you find out if the $_SERVER["AUTHENTICATE_CN"] variable is being populated? it's not in my phpinfo. I'm using iis7 as my web server, is there any way to configure it to populate the variable


 * Thanks for any help - Boozelclark 07:00, 20 May 2011 (UTC)

Problem with the Extension
When enabling this extension I get the following ErrorMessage:

Fatal error: Cannot make non static method AuthPlugin::getCanonicalName static in class Auth_remoteuser in /var/www/wiki/extensions/Auth_remoteuser/Auth_remoteuser.php on line 202

What can I Do to make it work?--Bayano 14:48, 23 March 2011 (UTC)

Require Once issue
The LocalSettings.php require line is out of date and should be updated to this

Unable to modify username
This extension worked beautifully right out of the box. Thank you. I'm now trying to modify the automatically generated usernames. Right now, usernames are defaulting to name@domain.com. (I've noticed that the extension tries to strip out the @domain.com, but it's not working.) Having the domain in there creates a few problems, so I'm trying to truncate the username to "name". I've tried:

$username = strstr( $username, '@', true);

in both the Auth_remote_user_hook and initUser functions, but it did nothing. If I log out and visit another page, it logs me back in as name@domain. Any suggestions? MatthewBurton 21:48, 1 July 2011 (UTC)


 * Fixed. I hadn't changed my $wgAuthRemoteuserDomain value from NETBIOSDOMAIN (line 80). Once I replaced that with my own domain, everything worked perfectly. MatthewBurton 21:29, 6 July 2011 (UTC)

Solved: $wgAuthRemoteuserName and $wgAuthRemoteuserMail inappropriately set:
Line 71 sets the variable during a ternary check even if $_SERVER["AUTHENTICATE_CN] is NOT set: $wgAuthRemoteuserName = isset( $_SERVER["AUTHENTICATE_CN"] ) ? $_SERVER["AUTHENTICATE_CN"] : '' ; The ternary check should set $wgAuthRemoteuserName to 'null' when $_SERVER["AUTHENTICATE_CN] is not set: $wgAuthRemoteuserName = isset( $_SERVER["AUTHENTICATE_CN"] ) ? $_SERVER["AUTHENTICATE_CN"] : null; Otherwise, the later check in initUser line 374 succeeds where it should fail: if ( isset( $wgAuthRemoteuserName ) ) { $user->setRealName( $wgAuthRemoteuserName ); } else { $user->setRealName( '' ); } This is also true of $wgAuthRemoteuserMail check. --Secmanz 02:43, 8 October 2011 (UTC)

Error messages as of MediaWiki 1.18
Date: 8 january 2012 The following errors turn up in the Apache log file after installing MediaWiki 1.18.0 although everything works fine:

PHP Strict Standards: Declaration of Auth_remoteuser::modifyUITemplate should be compatible with that of AuthPlugin::modifyUITemplate in /volume1/web/w/extensions/Auth_remoteuser/Auth_remoteuser.php on line 202, referer: https://MyServer/MyWikiPage PHP Strict Standards: Declaration of Auth_remoteuser::addUser should be compatible with that of AuthPlugin::addUser in /volume1/web/w/extensions/Auth_remoteuser/Auth_remoteuser.php on line 202, referer: https://MyServer/MyWikiPage PHP Strict Standards: Declaration of Auth_remoteuser::initUser should be compatible with that of AuthPlugin::initUser in /volume1/web/w/extensions/Auth_remoteuser/Auth_remoteuser.php on line 202, referer: https://MyServer/MyWikiPage

I use the following versions: MediaWiki 1.18.0 (r108167) PHP       5.3.3 (apache2handler) MySQL     5.1.49 AutomaticREMOTE USER 1.1.4 (r108355)

Multiple Domain Authentication
Our corporation uses multiple domains.

It seems it would make sense if the $wgAuthRemoteuserDomain was an array. $wgAuthRemoteuserDomain = array( "DOMAIN1", "DOMAIN2", "DOMAIN3" );

Anyone else have a need for more support?

Case Insensitive Domains
Our wiki lets users login with either NTLM or a typed username/password from the 403 challenge. This has the effect that users type the domain differently, often lowercased, which allows them to login, but results in duplicate user names.

Has anyone else seen this / would like this fixed?

I'm guessing it's due to using  rather than   to remove the domain part of the name, but I'm not sure what (if any) other side-effects this might have? Perhaps this should be made optional in case users have case sensitive domains?

1.19.0 email and real name not being created.
i'm trying out this extension on 1.19.0. i enabled the extension, and it logs me in successfully, but the real name and email address is not being set.

i've set $wgAuthRemoteuserDomain = "MYDOMAIN.COM"; $wgAuthRemoteuserMailDomain = "mydomain.com";

is there something i'm missing?

i do see in the code the following:

// You probably want to edit the initUser function to set the users real name // and email address properly for your configuration.

which is amusing in that, yes i do want to do that, but without a background in php, i don't know what to change in initUser to achieve this, especially as there are no inline comments at that point. looking at the code further, i get the feeling that initUser should be setting real name and email but it isn't because of the section above:

/* User's name */ $wgAuthRemoteuserName = isset( $_SERVER["AUTHENTICATE_CN"] ) ? $_SERVER["AUTHENTICATE_CN"] : '';

/* User's Mail */ $wgAuthRemoteuserMail = isset( $_SERVER["AUTHENTICATE_MAIL"] ) ? $_SERVER["AUTHENTICATE_MAIL"] : '';

this part of the code however i'm not understanding at all. i've also tried setting  to   per the note above, but it hasn't changed anything.
