Question

I’m trying to add users to IIS Manager via web.config, but whenever I add the following lines, the web site stops working and says web.config is not valid.

The web site works if I add those lines in administration.config, but I like to keep the scope small by sticking with web.config.

<system.webServer>
  <management>
    <authorization defaultProvider="ConfigurationAuthorizationProvider">
      <authorizationRules>
        <scope path="/MyApp">
          <add name="domain\user" />
        </scope>
      </authorizationRules>
    </authorization>
  </management>
</system.webServer>

A simple Google search can answer your question.

IIS Management element

From that page:

Note: The settings in the management element can only be configured in the Administration.config file.
