To install Next Active Directory Integration you need at least WordPress 5.6 and PHP 8.1.

Although only tested with Apache 2.2 and 2.4 Next ADI should work with all other common web servers like nginx and IIS.

Next Active Directory Integration requires a few PHP modules to be enabled. Please verify in your php.ini that the modules ldap, mcrypt and mbstring are activated. But it is very likely, that mcrypt is already enabled and not listed in the php.ini. If you are planning to use encryption for your LDAP connection - which we highly suggest - you although need openssl to be enabled.

Open your php.ini, located e.g. in c:\windows\php.ini or your PHP installation directory and enable the extensions by removing the prepending semicolon (“;“). If the “extension” entries do not exist, you can simply add them:

; Dynamic Extensions ;
; ...
; required by ADI 2.x
; required by LDAP/S and STARTTLS

After you have saved the changes you have to restart your webserver.
