[Zope-CMF] memberdata + mysql integration

[Miles]

Hi,

I need to integrate a zope instance with memberdata that is stored in 
mysql (generated by a pre-existing discuss forum).  Users need to be 
authenticated by mysql, and the memberdata tool should be able to get 
and set their properties, as well as adding new users etc.

What is currently considered the best practice way of achieving this 
sort of integration?  I have looked briefly at:

  - PAS: looks the most pluggable but doesn't seem to have a MySQL 
plugin and is quite complicated at first glance.

  - MySQLUserFolder: appears to fit the bill for authentication but no 
changes since late 2005.

  - ExUserFolder: also looks like it will deal with authentication but 
no changes since early 2005.

In particular, none seem to deal with the memberdata properties that 
should be assigned to a user, though I may not be looking hard enough.

How far will I get with existing products, and how much code (aside from 
entering column and table names etc) will I need to write?

Thanks for your help,

Miles
