Download mod_authn_ntlm

Please download latest module binary (.so file) from https://github.com/TQsoft-GmbH/mod_authn_ntlm/tree/master/bin and copy it to your Apache modules directory.

Load the module in Apache

Edit your httpd.conf to load the mod_auth_ntlm module during startup:

LoadModule auth_ntlm_module modules/mod_authn_ntlm.so

Configure NTLM (SSPI) authentication for your WordPress installation

Depending upon your Apache and WordPress environment you can enable this in your httpd.conf or .htaccess configuration file.

<Location /authenticate >
	AuthName "WordPress"
	AuthType SSPI
	NTLMAuth On
	NTLMAuthoritative On
	<RequireAll>
		<RequireAny>
			Require valid-user
			# ensure a non-existing user can't login
			# Require sspi-user domain\invalid
		</RequireAny>
	</RequireAll>
</Location>

After you have made the changes to the httpd.conf restart the Apache webserver.
