[Tikiwiki-users] removing permissions of a whole structure

[Guilherme P. P. <gp...@gm...>]

hi people

I want to avoid that users move nodes out of the structure, since they
become new structures and I didn't find a way to move back the new
structure as a node of original structure.

I tried removing tiki_p_edit_structures permission from the groups and
from some pages, with no effect. users can still move these pages
inside the structure.

Do I need to remove tiki_p_edit_structures from all pages from the
structure ? is there a way to do this without doing it page by page?
(maybe directly with mysql ?)

thanks for any help,
Guilherme
