[Zope] downgrading from 2.1.x from 2.2.0 to use NTuser authentication

[Erik Myllymaki]

I would really like to use the jc/ntuserfolder products but see that they
haven't been brought up to speed with the new 2.2.x security model. Will
downgrading to 2.1.x render my site inaccessible? What will I have to change
security wise so I can use these pages from the old version?

Alternatively, I might take a stab at bring the jc/ntuserfolder up to date
with the new security model - any insight from those in the know
appreciated(am I underestimating that task?).

Thanks,
