I have a multi-site Umbraco instance where I would like to restrict a user to have editor access to only a few sites. When removing page permissions for the user, I would expect the user to not have access to the removed pages after logging in to Umbraco. After the user logs back in, they can still view and edit the sites which have had their page permissions removed.

What is the expected behaviour for user permissions? Is there any detailed documentation on User Permissions? I've been unable to find any.

Thanks,
Dan.
