User and folder management !

Hi,

I'm currently busy with an external application written in VBA/Vb.NET to assign in "batch" the differents rights to folder !

I can create folder, user, and usergroup.

But i'm still blocked for the assigning aspects.

- add usergroup to folder

- assign "access level(generic name)" to a group

ex: 'RestrictedAllow' is a access level , define inside the cms

i want to assign this to a group

Thanks.
