Win9x clients completely break when the smb.conf parameter case sensitivity = Yes is set. The behavior I'm seeing is that clients cannot cd into directories when case sensitive = yes. If this is something that CANNOT work (which is what I'm hearing from Samba Team members), we need to document it in big letters in the man page and the howto.
documented in smb.conf(5)
