  1. POProgrammatically unlocking IIS configuration sections in Powershell
    text
    copied!<p>I am writing a powershell script to create and configure a number of websites and virtual directories. I am using the .NET Microsoft.Web.Administration assembly. I have created a new application under the default website and added a new virtual directory to it and it all works well. What I'm trying to do now is set up the authentication options for the virtual directory. I am doing the following in powershell:</p> <pre><code>[System.Reflection.Assembly]::LoadWithPartialName("Microsoft.Web.Administration") $oIIS = new-object Microsoft.Web.Administration.ServerManager $oWebSite = $oIIS.Sites["Default Web Site"] $oApp = $oWebSite.Applications["/MyApp"] $oConfig = $oApp.GetWebConfiguration() $oAnonAuth = $oConfig.GetSection("system.webServer/security/authentication/anonymousAuthentication") $oAnonAuth.SetAttributeValue("enabled", "False") </code></pre> <p>However, the SetAttributeValue command gives me the following error:</p> <p>"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"</p> <p>From what I have read elsewhere, there are some suggestions to change the XML file for the application to allow overriding. I don't want to have to do that - is there any way to programmatically unlock the configuration to allow me to change it? I don't want any user input into this process at all..</p> <p>Thanks for any help, Al.</p> <hr> <p>Found the answer I was looking for - but being a new user I can't answer my own question for 24 hrs..</p> <p>I think I found the code below on this site, but my machine has since rebooted so I've lost the page. However, the following seems to work:</p> <pre><code># # Allow overriding of the security settings. # $oGlobalConfig = $oIIS.GetApplicationHostConfiguration() $oConfig = $oGlobalConfig.GetSection("system.webServer/security/authentication/anonymousAuthentication", "Default Web Site/mySite") $oConfig.OverrideMode="Allow" $oIIS.CommitChanges() # # Following the commit above, we need a new instance of the configuration object, which we can now # modify. # $oGlobalConfig = $oIIS.GetApplicationHostConfiguration() $oConfig = $oGlobalConfig.GetSection("system.webServer/security/authentication/anonymousAuthentication", "Default Web Site/mySite") $oConfig.SetAttributeValue("enabled", "False") $oIIS.CommitChanges() </code></pre>
