The design will carefull take into account backward compatibility. You
can still have a user folder that doesn't know about groups, in which
case the users won't have groups associated to them. No problem.

The design goes like that: the local role machinery is patched to take
into account groups *if the user folder can deal with them*. Otherwise
nothing at all is changed.

The folders can be converted one by one when needed. Someone already
sent me a patch for LDAPUserFolder. XUF can follow whenever they're
ready, I'll be ready to help.

If you look at current NUF, the main changes would be added tests before
any use of the user.getGroups() method [which I'll rename to
user.getUserGroups() because getGroups is already taken by
LDAPUserFolder].

In any case I'll put the code in a CVS branch sometime this week or the
next, and we can discuss the impact. Code speaks :-)
