Installation

• Download and move the extracted LDAPAuthentication2 folder to your extensions/ directory.
  Developers and code contributors should install the extension from Git instead, using:

  cd extensions/
  git clone https://gerrit.wikimedia.org/r/mediawiki/extensions/LDAPAuthentication2
  

• Add the following code at the bottom of your LocalSettings.php file:

  wfLoadExtension( 'LDAPAuthentication2' );
  

• Configure as required.
• Done – Navigate to Special:Version on your wiki to verify that the extension is successfully installed.

Versioning

LDAP Stack Extensions are targeted/qualified for MediaWiki LTS releases only.
However, this table helps to determine which extension-releases to use across all recent versions.

Migration from PluggableAuth 5

In REL1_39 branch LDAPAuthentication2 was adapted to PluggableAuth 6.

So in case of migration from REL1_35-REL1_38 (PluggableAuth 5) to REL1_39 (PluggableAuth 6) some configuration needs to be changed. Here is the example of the old configuration:

// In any case we need to specify LDAP domain configs
$LDAPProviderDomainConfigs = "$IP/../ldapprovider.json";

// Local login is enabled
$wgPluggableAuth_EnableLocalLogin = true;
$LDAPAuthentication2AllowLocalLogin = true;
...
$wgPluggableAuth_Class = "MediaWiki\\Extension\\LDAPAuthentication2\\PluggableAuth";
$wgPluggableAuth_ButtonLabel = "Log In (PluggableAuth)";

As a result, "Log In (PluggableAuth)" login button will appear on login page, with "domains" dropdown.

Domains list is obtained from the domain configs file. Let's assume that we have "ldap1" and "ldap2" domains configured there, still it is not reflected in PluggableAuth 5 configuration.

Here is how such configuration should be changed to be compatible with PluggableAuth 6:

// In any case we need to specify LDAP domain configs
$LDAPProviderDomainConfigs = "$IP/../ldapprovider.json";

// If local login is supported as well, then these globals are still needed
$wgPluggableAuth_EnableLocalLogin = true;
$LDAPAuthentication2AllowLocalLogin = true;
...
$wgPluggableAuth_Config['Log In (LDAP1)'] = [
    'plugin' => 'LDAPAuthentication2',
    'data' => [
        'domain' => 'ldap1'
    ]
];

$wgPluggableAuth_Config['Log In (LDAP2)'] = [
    'plugin' => 'LDAPAuthentication2',
    'data' => [
        'domain' => 'ldap2'
    ]
];

Here "ldap1" and "ldap2" are domains which are configured in domain configs file.

As a result, "Log In (LDAP1)" and "Log In (LDAP2)" login buttons will appear on login page.

So the main difference is that:

• There is only one login button per LDAP domain.
• Now $wgPluggableAuth_Config global should be used.
• $wgPluggableAuth_Class global is not used anymore.
