I'm installing this OEM API on Windows 10 under IIS 7. In the basic settings for the site, I want to set Pass-through verification to IUSR. As I understand from the Microsoft docs
This built-in account does not need a password and will be the default identity that is used when anonymous authentication is enabled.
And sure enough, in my applicationHost.config there's
<anonymousAuthentication enabled="true" userName="IUSR" />
So in IIS, in the basic settings, under Pass-through-verification I click Connect as, then turn on the radio button for Specific user, click Set..., for user name I type in IUSR, I leave the password fields empty and then click OK.
When I then test settings, Verification fails because of invalid user-references (translated from Dutch:)
the references to access the physical path are invalid. Check the references and test this setting again.
(Note: when I leave this setting on 'Application user (Pass-through-verification)', I get this warning. That's not the question.)
Yet the IUSR does have read and execute rights in the API directory.
What am I doing wrong?
