Set the Company property of a user using dotnet 3.5

Hi guys

I have been unable to set up the company property of a user using the dot 3.5 way. Here is the bit of code I use :

   Dim u As New UserPrincipal(SharedObjects.PrincipalContext)




   u.Surname = ln

   u.SamAccountName = login

   u.EmailAddress = email

   u.Name = ln

   u.DisplayName = fn & " " & ln

   u.Enabled = True



   Dim context As PrincipalContext =  New PrincipalContext(ContextType.Domain, SharedObjects.LDAPName(), "OU=Users,OU=" & My.Settings.OUName & "," & SharedObjects.LDAP_DomainName(), SharedObjects.UserLogin(), SharedObjects.UserPassword())


   u.Save(context)




'THIS IS THE TRICK!
   Dim de As DirectoryEntry

   de = DirectCast(u.GetUnderlyingObject(), DirectoryEntry)

   de.Properties("Company").Value = entity

   de.CommitChanges()

Actually I am creatinf a user (using UserPrincipal, principalContext, etc) but if I want to set up the company name for this user, the only way I found to archive this is using the old 2.0 way with DirectoryEntry. IT WORKS but I don't like it.

Is there a better way to do that ?

cheers mates
