IIS 7 how to preserve website subfolder Authentication settings

问题

In IIS you can set folder-level settings using the Features view (see screenshot). I want to disable Anonymous authentication for several subfolders of my website and save those settings to source control. I want to know where does IIS save these settings. They are not in the website web.config or the web.config inside subfolders. Is there anyway I can save the IIS settings with the source code or do I have to perform these tasks with each fresh deployement?

回答1:

Add the following to your root web.config for each folder you want to secure:

<location path="secure_folder">
    <system.webServer>
        <security>
            <authentication>
                <anonymousAuthentication enabled="false" />
                <basicAuthentication enabled="true" />
            </authentication>
        </security>
    </system.webServer>
</location>

The above assumes that you're using Basic Authentication.

Alternatively create a web.config in each sub folder to be secured with pretty much the same (except without the <location> tag:

<system.webServer>
    <security>
        <authentication>
            <anonymousAuthentication enabled="false" />
            <basicAuthentication enabled="true" />
        </authentication>
    </security>
</system.webServer>

If receive an error such as:

There was an error while performing this operation.

Details:

Filename: \?\d:\sites\play1\www\web.config

Line number: 15

Error: This configuration section cannot be used at this path. This happens when the section is locked at a parent level. Locking is either by default (overrideModeDefault="Deny"), or set explicitly by a location tag with overrideMode="Deny" or the legacy allowOverride="false".

Then it means that the configuration settings for <anonymousAuthentication> and <basicAuthentication> haven't been delegated Read/Write permissions.

You can adjust this by launching IIS Manager and opening the Feature Delegation manager:

When you do this you'll see a list of features that can be controlled and their delegation state:

Right click on Authentication - Anonymous and select Read/Write. Do the same for Authentication - Basic.

This feature delegation setting will be applied globally across all sites on the server, however it is possible to fine tune this to specific sites using Custom Site Delegation.
