[Zope] MySQL password scheme

Hi, we have had a problem to use an existing userbase stored in a MySQL table where the passwords are stored with the default encryption of PASSWORD() (hash code function). I solved this problem by using SimpleUserFolder and extend the password schemes zope with a MySQL password scheme. If you are interested, yu can found it under collector issue 435. I hope the Zope guys will include it into the core rsn, the patch is short and uncritical. Dirk
