PowerShell - Working with SID

I recently had to write mutliple scripts that were using a few different methods to convert SID to name and vice versa for Local and Active Directory accounts.

Here Here is a PowerShell tip to convert Active Directory account from Name to SID and vice versa

Local Account

Name to SID

With PowerShell and .Net

$objUser = New-Object System.Security.Principal.NTAccount("LOCAL_USER_NAME")
$strSID = $objUser.Translate([System.Security.Principal.SecurityIdentifier])
$strSID.Value

With WMI

wmic useraccount where name='test_user' get sid

SID to Name

With PowerShell and .Net

$objSID = New-Object System.Security.Principal.SecurityIdentifier `
    ("S-1-5-21-1454471165-1004335555-1606985555-5555")
$objUser = $objSID.Translate( [System.Security.Principal.NTAccount])
$objUser.Value

With WMI

wmic useraccount where sid='S-1-3-12-12451234567-1234567890-1234567-1434' get name

Domain Account

Name to SID

With PowerShell and .Net

$objUser = New-Object System.Security.Principal.NTAccount("MyDomain", "TestUserAccount")
$strSID = $objUser.Translate([System.Security.Principal.SecurityIdentifier])
$strSID.Value

With LDAP/ActiveDirectory module

Get-ADUser -Identity 'TestUserAccount' |
select-Object -Property SID

SID to Name

With PowerShell and .Net

$objSID = New-Object System.Security.Principal.SecurityIdentifier `
    ("S-1-5-21-1454471165-1004335555-1606985555-5555")
$objUser = $objSID.Translate( [System.Security.Principal.NTAccount])
$objUser.Value

With LDAP/ActiveDirectory module

Get-ADUser -Identity S-1-3-12-12451234567-1234567890-1234567-1434
