从SQL Server获取Active Directory GUID

Question

I'm getting User GUID from Active Directory in C# using the code below:

var GUIDID = "";

using (var domainContext = new PrincipalContext(ContextType.Domain, domain))
{
     using (var user = UserPrincipal.FindByIdentity(domainContext, IdentityType.SamAccountName, userNameToUse))
     {
         if (user != null)
         {
            GUIDID = user.Guid.ToString();
         }
     }                           
 }

So the output from the code above for a particular person is:

7b8b17f1-9997-46ac-bec4-c747eed2de33

What I now want to do is query Active Directory from SQL Server 2008 using that GUIDID . However, the issue I'm running into is I don't know the name of the column .

I tried to search for the same person (using their full name) from SQL using the code below:

SELECT cn, objectGUID
FROM  'LDAP://xxx.local/OU=xxx Users,DC=xxx,DC=xxx'
WHERE objectClass = 'User' AND cn = 'John Smith'

Yet, objectGUID , OBjectSID are not the same as the GUIDID my C# code is returning.

I also tried to select * in my SQL query, but it only returns the path.

Any suggestion on how I can find out the GUID COLUMN name from SQL Code?

Thanks

The solution is really simple. I needed to convert the ObjectID

SELECT CONVERT(UNIQUEIDENTIFIER,0xF1178B7B9799AC46BEC4C747EED2DE33);

Hope it helps somebody.
