On an internal mailing list someone asked how to get the SID for the current context using PowerShell.  Chris Bellée correctly responded:

([Security.Principal.WindowsIdentity]::GetCurrent()).user.accountdomainsid.value

 

I used this to create a script:  Get-Me.ps1

# Get-Me.ps1

[Security.Principal.WindowsIdentity]::GetCurrent()

 

PS> .\get-me.ps1
