I am having specific issues in regards to IIS 8.5, Permissions, and Auditing. I have a PHP application running under KanboardPool identity and I've properly set permssions on the application 'data' folder to 'IIS APPPOOL\KanboardPool' to full control.
In addition, I've set IIS_IUSRS to Read, execute, and list on the same folder including parent. Regardless; I still get permission denied failures.
I've try to AUDIT file access failures without much luck: First through GPO Domain Policy -> Computer Configuration -> Windows Settings -> Security Settings -> Advance Auditing -> Audit File Access Success and Failure. Which didn't log any Audit Failures. Same procedure through Domain Controller Policy and at last through Local Policy for whatever reason. Audit Policy Change is added then removed later in succession.
Through ACL, I ran a Effective Access test on selected Principal 'IIS APPPOOL\KanboardPool' which passed with flying colors. Now I am just stumped?
