I am completely new to Windows PowerShell.
I am trying to change the IIS's default web site's SSL settings from
Required SSL = false and client certificate = ignore to
Required SSL = true and client certificate = accept using powershell (I have to configure it to ansible playbook)
I have searched but didn't get any solution.
Kindly help. Any leads or solution will be appreciated. :) Thank You
Actually, Set-WebConfiguration does not work on attributes in a reliable manner.
What you instead want to use is:
$cfgSection = Get-IISConfigSection -Location "{siteName}/{appName}" -SectionPath "system.webServer/security/access";
Set-IISConfigAttributeValue -ConfigElement $cfgSection -AttributeName "sslFlags" -AttributeValue "Ssl, SslNegotiateCert";
Note that after you use Set-IISConfigAttributeValue (and commit the change, if you're doing a delayed commit), you can't use that instance of $cfgSection to make subsequent changes; you'll have to fetch another instance first.
PS: If you want to see what's in the config before you mess with it (or afterwards), the authoritative settings are here: C:\Windows\System32\inetsrv\config\applicationHost.config
Or you can continue the above code and add Get-IISConfigAttributeValue -ConfigElement $cfgSection -AttributeName "sslFlags";
