Moodle installation is unable to access data directory, even though I have given full permission to the iis user. When I give full permission to Everyone it works fine, but I can't give full permission to everyone because of the security issues. What is the user whom I should be giving the permission to? Who is missing from the iis user group?
Server details :
Windows Server 2012 R2 , IIs, php 7.1.11, Moodle 3.3.2+, sql server driver 4.3.
