Get SID from user

[Patrick Ma]

Hi community,

I love to use cassia and in my case I write an application for terminalserver.
It is very easy to get userinformation (with ITerminalServicesSession objects) - but how do I get the SID from this ITerminalServicesSession object / user?

Thanks,
Patrick

You can't as the Cassia SessionID does not hold the SID as a property. I use the following, using System.DirectoryServices.AccountManagement. I use VB.NET but this could simply be used in any other .net language.

Imports System.DirectoryServices.AccountManagement

Imports CassiaDim Domain As 

<define class here>

Dim Domain As String = "CONTOSO"

Dim DomainDN As String = "DC=contoso,DC=com"

Dim DomainContext As New PrincipalContext(ContextType.Domain, Domain, DomainDN)

Dim TSServer As ITerminalServer

Dim TSManager As New TerminalServicesManager()

TSServer = TSManager.GetLocalServer()

For Each Session As ITerminalServicesSession In TSServer.GetSessions

   Console.WriteLine("Sid: " & UserPrincipal.FindByIdentity(DomainContext, IdentityType.SamAccountName, Session.UserName).Sid.ToString)

Next

thanks for input @ Robert Gijsen. 

I solved this with this code: 

public String GetSID(ITerminalServicesSession UserSession)

        {

            NTAccount NTAccountUser = new NTAccount(UserSession.UserName);

            SecurityIdentifier SID = (SecurityIdentifier)NTAccountUser.Translate(typeof(SecurityIdentifier));

            String SIDString = SID.ToString();

            return SIDString;

        }

Maybe it is not perfect. but it works. thanks.
