  Hi,

That's right and I was quite stupid !!!
By BTreeFolder2 just had false duplicated keys because of these extra
spaces invisible in my HTML page...

In fact, the origin of the problem is my LDAP server, which accept
authentication even when the user ID includes spaces !!
I just thought that this shouldn't be !!  Using a simple "strip" nearly
solved my problem... 

Thanks,

  Thierry


P.S. : I said that my problem was nearly solved because each user
profile is private, so the user identified with the user id "   tflorac"
can't access the profile called "tflorac". Is there any way to alter the
user authentication name ??
