Apache ( the one that comes with the dukowiki on a stick) and IIS
See
https://www.dokuwiki.org/plugin:authad#server_configuration for a guide on how to install the missing php module for IIS (I'd be surprised if it's not installed in microApache). I have never used microApache but that documentation is the first place I'd look for information on how to set up Active Directory (after which I'd check my settings in Configuration Manager and look at the debug info).
Does microApache produce an error log? If so, post the relevant bits here and maybe someone whose knowledge of Active Directory is not dangerously outdated may be able to help.
for IIS its: Server/inetpub/wwwroot/dokuwiki
See
https://www.dokuwiki.org/install:iis for permissions for IIS.
For both (micro)Apache and IIS - did you follow this
https://www.dokuwiki.org/plugin:authad?
Apologies if you've already followed those guides.
