Thread:Project:Support desk/Localsettings.php not Found by non-admin users/reply (4)

I found the root cause of the problem - when I switched over to using Windows Authentication the security group that gated user access did not have the same permissions as the IIS_IUSRS group that controls anonymous access. I had to mirror the access levels of IIS_USRS to my domain security group both in my MediaWiki site folder and the PHP folder. Once done the settings file is found and the site loads as expected.
