How To Install the App-V Databases and Convert the Associated Security Identifiers (SID) Using PowerShell

Updated: November 1, 2012

Applies To: Application Virtualization 5.0

Use the following PowerShell procedure to convert any number of Active Directory Domain Services (AD DS) user or machine accounts into formatted Security Identifiers (SIDs) both in the standard format and in the hexadecimal format used by Microsoft SQL Server when running SQL scripts.

Before attempting this procedure, you should read and understand the information and examples displayed in the following list:

  • .INPUTS – The account or accounts used to convert to SID format. This can be a single account name or an array of account names.

  • .OUTPUTS - A list of account names with the corresponding SID in standard and hexadecimal formats.

  • Examples -



    .\ConvertToSID.ps1 DOMAIN\user_account1 DOMAIN\machine_account1$ DOMAIN\user_account2 | Format-List.



    $accountsArray = @("DOMAIN\user_account1", "DOMAIN\machine_account1$", "DOMAIN_user_account2")

    .\ConvertToSID.ps1 $accountsArray | Write-Output -FilePath .\SIDs.txt -Width 200

        }
    
    
    
    }
    

  3. Run the script you saved in step one of this procedure passing the accounts to convert as arguments.

    For example,

    .\ConvertToSID.ps1 DOMAIN\user_account1 DOMAIN\machine_account1$ DOMAIN\user_account2 | Format-List” or “$accountsArray = @("DOMAIN\user_account1", "DOMAIN\machine_account1$", "DOMAIN_user_account2")

    .\ConvertToSID.ps1 $accountsArray | Write-Output -FilePath .\SIDs.txt -Width 200”
