Q:

Reverse lookup of Terminal Services Home Folder withDirectory Services

I'm looking for a way to query the Terminal Services Home Folder property of user objects in Active Directory. My goal is to be able to perform a reverse lookup, finding the user(s) that use a particular home folder.
Normally to perform a search I would do something like this:
using (var search = new DirectorySearcher())
{
    // Find a user based on their telephone number
    search.Filter = "(telephoneNumber=999)"; 
    search.PropertiesToLoad.Add("displayName");
    var result = search.FindOne();
    if(result != null) {....}
}

But the Terminal Services settings don't seem to have a referable LDAP attribute name - in the past to set these values I've had to use the IADsTSUserEx interface with an existing DirectoryEntry to manipulate the TS profile and home folder properties. However this is only useful when I have the user account in question - it's not very practical to step through every user in a domain and create a DirectoryEntry object for them just to check their TS profile path.
Is there any practical way to perform a "WHERE User.TerminalServicesProfilePath=X" query in .NET?

A:

Nobody here so, I try an explanation. 
In Windows Server 2008 (and R2), the Terminal Services Terminal Server Runtime Interface takes the user parameters from the user Active-Directory attribute called userParameters. As explain in Microsoft documentation userParameter contains Terminal Server parameter as blob.
