PowerShell can easily verify a password against a domain account. In other words, you can bind script logic to passwords maintained in Active Directory.
Here is the code required to send a password to AD and get back a Boolean value: $true if the password is correct, else $false:
# specify user name and user domain $UserDomain = $env:USERDOMAIN $UserName = $env:USERNAME $Password = Read-Host -Prompt "Enter password to test" # test password Add-Type -AssemblyName System.DirectoryServices.AccountManagement $ContextType = [System.DirectoryServices.AccountManagement.ContextType]::Domain $PrincipalContext = [System.DirectoryServices.AccountManagement.PrincipalContext]::new($ContextType, $UserDomain) $PrincipalContext.ValidateCredentials($UserName,$Password)
Note that this code requires an Active Directory and does not work with local accounts. By default, it uses your current account details. Adjust the $UserDomain, $UserName, and $Password variables accordingly. Note also that ValidateCredentials()checks clear-text string passwords. Be careful and do not store clear-text passwords in scripts. Also, better not ask users to enter passwords as clear text.
Your learning points:
- PowerShell can easily connect to Active Directory and ask for a password validation
