Must return IRemoteUserStringParser object. Only used in case of auto-authentication provided by Erweiterung:Auth remoteuser .
AutoAuthRemoteUserStringParser	"domain-backslash-username"	Configures which parser is needed to extract domain and username from a provided domain-username. Erlaubte Werte sind: "domain-backslash-username" (Use this if $_SERVER['REMOTE_USER'] = "SOMEDOMAIN\\Some username") "username-at-domain" (Use this if $_SERVER['REMOTE_USER'] = "some.username@somedomain.local") Only used in case of auto-authentication provided by Auth remoteuser.
AutoAuthUsernameNormalizer	""	A callback that allows to modify the username when Erweiterung:Auth remoteuser is used for network based authentication. E.g. "strtolower".

Example 1

If you want to configure this in LocalSettings.php you can extend the configuration for LDAPProvider like in this example:

$LDAPProviderDomainConfigProvider = function() {
	$config = [
		'LDAP' => [
			'connection' => [
				...
			],
			'authorization' => [
				'rules' => [
					'groups' => [
						'required' => [ "groupname" ]
					]
				]
			]
		]
	];
...

Example 2

Here is a complete example LocalSettings.php configuration for Active Directory:

$LDAPProviderDomainConfigProvider = function()
{
	$config =
	[
		"example.com" =>
		[
			"connection" =>
			[
				"server" => "ldap.example.com",
				"user" => "cn=ldap,cn=Users,dc=example,dc=com",
				"pass" => "password",
				"basedn" => "dc=example,dc=com",
				"groupbasedn" => "dc=example,dc=com",
				"userbasedn" => "dc=example,dc=com",
				"searchattribute" => "samaccountname",
				"searchstring" => "USER-NAME@example.com",
				"usernameattribute" => "samaccountname",
				"realnameattribute" => "cn",
				"emailattribute" => "mail",
				"grouprequest" => "MediaWiki\\Extension\\LDAPProvider\\UserGroupsRequest\\GroupMember::factory"
			],
			"authorization" =>
			[
				"rules" =>
				[
					"groups" =>
					[
						"required" => [ "cn=Developers,cn=Users,dc=example,dc=com" ]
					]
				]
			],
			"groupsync" =>
			[
				"mechanism" => "mappedgroups",
				"mapping" =>
				[
					"sysop" => "cn=Developers,cn=Users,dc=example,dc=com",
					"bureaucrat" => "cn=Developers,cn=Users,dc=example,dc=com"
				]
			],
			"userinfo" =>
			[
				"email" => "mail",
				"realname" => "cn",
