Hi Wildcats,
Welcome to Centrify and thanks for your inquiry.
According to your description, it looks like the problem is: logged in user did not have the permission in accessing the Webpage.
The permission denied is the access control rejected on the IIS server side. It will be better to check if your user account is having proper permission to access the page.
Please feel free to contact us if you need any assistance.
Best Regards,
Albert
