Change Forms Authentication in Feature Delegations in IIS using PowerShell

To change Forms Authentication in Feature Delegations in IIS using PowerShell, you can use the WebAdministration module, which provides a set of cmdlets for managing IIS.

Here's an example PowerShell script that demonstrates how to change Forms Authentication in Feature Delegations in IIS:

powershellCopy code
Import-Module WebAdministration



# Specify the name of the IIS site

$siteName = "Default Web Site"



# Get the site object

$site = Get-WebSite $siteName



# Set the authentication mode for Forms Authentication

$authConfig = $site.limits | Select-Object -ExpandProperty properties | Where-Object {$_.name -eq "authenticationMode"}

$authConfig.value = "Forms"



# Save the changes to the configuration file

Set-WebConfigurationProperty -filter /system.web/authentication -name mode -value "Forms"



# Enable Forms Authentication in Feature Delegations

$featureName = "Authentication - Forms"

Set-WebConfiguration -filter /system.webServer/security/authentication/anonymousAuthentication -value @{enabled="True"} -pspath "IIS:\Sites\$siteName" -Location $featureName

Set-WebConfiguration -filter /system.webServer/security/authentication/windowsAuthentication -value @{enabled="False"} -pspath "IIS:\Sites\$siteName" -Location $featureName

In this script, we first import the WebAdministration module, which provides the Get-WebSite, Set-WebConfigurationProperty, and Set-WebConfiguration cmdlets.

We then specify the name of the IIS site we want to modify, and retrieve the site object using the Get-WebSite cmdlet.

Next, we set the authentication mode for Forms Authentication using the Set-WebConfigurationProperty cmdlet, and enable Forms Authentication in Feature Delegations using the Set-WebConfiguration cmdlet.

Note that you may need to modify this script to suit your specific requirements. For example, you may need to specify a different site name, or modify the settings for other authentication methods.

Also, be sure to run the script with administrative privileges, as modifying IIS requires elevated privileges.
