Adding Security to a Folder

I've got functionality in an application that allows me to log on as a specific user; that allows me to test the security for that user or a class of users. 

The problem is that part of the functionality for the app is to write config files to the user's profile that saves form/grid state. When I do this with my admin account, I end up writing a config file that has my security; and then when the user logs on that can't access the config file and that generates a permissions error (can't open file)

So... Below is code to add myself AND the user to the security profile for a folder so that we're both covered. No more perm errors.

Dim directoryProperties As System.IO.DirectoryInfo = New DirectoryInfo(App.ApplicationDataDirectory)
 
'Get a DirectorySecurity object that represents the current security settings.
Dim dSecurity As System.Security.AccessControl.DirectorySecurity = directoryProperties.GetAccessControl()
 
'Set the new access settings for my user
dSecurity.AddAccessRule(New FileSystemAccessRule("sgray@mydomain.com", FileSystemRights.FullControl, InheritanceFlags.ContainerInherit, PropagationFlags.None, AccessControlType.Allow))
dSecurity.AddAccessRule(New FileSystemAccessRule("sgray@mydomain.com", FileSystemRights.FullControl, InheritanceFlags.ObjectInherit, PropagationFlags.InheritOnly, AccessControlType.Allow))
 
'add security for users other than me
Dim strUser As String = String.Format("{0}@mydomain.com", App.UserName)
Select Case App.UserName.ToUpper
    Case "SGRAY"
    Case Else
        dSecurity.AddAccessRule(New FileSystemAccessRule(strUser, FileSystemRights.FullControl, InheritanceFlags.ContainerInherit, PropagationFlags.None, AccessControlType.Allow))
        dSecurity.AddAccessRule(New FileSystemAccessRule(strUser, FileSystemRights.FullControl, InheritanceFlags.ObjectInherit, PropagationFlags.InheritOnly, AccessControlType.Allow))
End Select
 
 
directoryProperties.SetAccessControl(dSecurity)
