Access Control

Several months ago, I was tasked with creating some way to assign roles to users in groups. I installed the og roles module. What I discovered was that this module simply assigned a role to a user, not to a user in a particular group. I realized what I needed was a way to assign a role to a user in a way so that the user would only have this role in this particular group, not sitewide and certainly not in all groups. To do this, I needed to understand Drupal permissions and Access Control worked. My progress on this particular task is here: http://drupal.org/node/87679

Fast forward a few months later, when I was trying to use OG and Taxonomy Access Control (TAC). To my horror, I discovered that if a node was posted to a group, a user who was not in the group could access the node if he had access to the Taxonomy term. And, vice versa, if a user was in a group that the node belonged to, but DID NOT have access to the Taxonomy term, he could still access the node. This, in my opinion, was two Access Control systems tolerating each other, not working together. My progress on ths particular task is noted here: http://drupal.org/node/122712

So, I set about, merrily hacking my way through, until I had resolved both issues. Unfortunately, hacking Drupal core code is not a very good long term solution. And, when I applied for a project for my og user roles module, Drupal Admin told me as much.

What I needed was an environment where I could discuss my ideas with like minded folk who wanted to achieve the same goal: Get Drupal Access Control to open up so that various ACS (access control systems) from various modules could work together instead of at cross purposes as they do now.

That's why I created this discussion group. My first task is to work on getting og user roles approved as a project. For that, I need to figure out how to get it working without hacking the user_access function in the user.module.

That's the plan.

Video on Node Access by hefox and drupaldojo

Check it out.
http://drupaldojo.blip.tv/file/3966199/

This session will cover how drupal controls access (who can view, create, edit, and delete) nodes/content. It will cover how drupal checks access, what modules can do to expand on that, and what you can do to insure that access is being checked. There will be some code, but mostly as background images.

Node access per user

I need a way for one or two super users to grant access to nodes on a per user basis. I have tried nodeaccess but I don't get a list of which users have access to which nodes which is very important. And in order to grant access I need to type in a user's name. In the node edit, I would like a list of user names in the system with a checkbox for access. With nodeaccess I can't see how to remove access for a user, I only see a way to grant it. I don't want to grant accesss by role, that would mean making a new role for every new user.

Cloning permissions from one node to another

I have a gallery setup whereby a gallery is a node and a gallery can have many child image nodes.

So far so good.

However, I would like to configure the setup so that when a user sets the node access permissions for the gallery (using UserRElationships Node Access), that same permission is applied to all child nodes.

I was thinking that this could be achieved in triggered rules, eg after a gallery is updated and after an image is created.

However I cant find out how I:

a) get the permissions of a particular node

and

b) set the permissions of a node.

Multiple Calendars

I wanted to poll this group to see what is the best way to manage access control multiple calendars in drupal.

I have a site where I need to be able to create some calendars public and some calendars private.

I need to control which users / roles has permissions to add an event to the calendar and which users /roles can view the calendar's events.

So far the only techniques I can think of are
1. Use Event content type with tags - create a vocabulary for Calendars with each term as a calendar - restrict with a taxonomy access control module

Hierarchical corporate structure for an intranet

We are a group of companies, i.e. our organizational structure consists of sub-companies, which again have sub-companies or departments, which also can have sub-departments and/or employees belonging to them. We need to have this organizational structure in our Drupal-based intranet system, both:

    Access control with Organic Groups

    Hi!
    I have a site with organic groups. When a user submits a content type within a group I would like the user to choose between three levels of access for the node:
    1) Open: the whole world (anonymous)
    2) Restricted: authenticated
    3) Private: members of the current group

    Point 3) is achieved with the 'Public' check-box provided by OG, but how do I get point 1) and 2)?

    I have tried simple_access and nodeaccess, but it doesn't seem to go well with OG. I am running D5.

    Any ideas how to get this three levels of access on each node submitted within a group?

    Idea: Menutree Permissions module - cascading menu-level access control by role/user ID - input needed :o)

    Hello everyone,

    I'm a complete newbie to writing Drupal apps and having not yet found anything which fits my needs properly, I'm setting out on writing a node access module which uses the site's primary navigation menu structure to define access permissions.

    I'm still at a very early stage of planning, and the use case for the module is pretty specific, so I haven't even begun to consider all the "what-if"s associated with, say, what happens when the site admin decides to reassign the primary menu.

    Proposal for a module: TAC fields

    I'm considering developing a module to extend the functionality of TAC to role/field combinations. TAC works wonderfully for controlling access to whole nodes based on their taxonomy, but it's all-or-nothing; the module currently has no way of leveraging the per-field access control offered by Content Permissions.

    I don't think the functionality belongs in TAC itself, as my proposed module is an additional layer of complexity that's specific to CCK content types.

    Making content type only for groups

    I have site where we are introducing groups, problem where i am stuck right now is i want to create new content type which can only be added by members who belong to atlest one group. if they are not member of any group they cant add that content type.

    taxonomy_access_user module review

    Hi drupal !

    I'm posting here to request a review of a module i'd just coded and that i would
    like to submit on drupal.org. Before doing this, i would like someone to review
    my module. Even if i'm pretty confident with my code which i've been testing for last
    2 weeks, i would prefer others' advice.

    About the module :
    This module provides taxonomy based user control for user but unlike modules already
    available on drupal.org with inheritance notion. For more information please read the
    README (available below).

    Thank you by advance.

    Code is available here on github : http://github.com/baloo/taxonomy-access-user
    Or as a tgz : http://github.com/baloo/taxonomy-access-user/tarball/master

    Access Control for Administrative Tasks/Areas

    Something I have had issues with on multiple sites I have worked on is administrative areas and permissions.

    Example:
    If I build a site for a client and then decide I want the client to be able to edit certain areas of the admin panel ("/admin/settings/site-information") but I don't want them to have full access to the administration area then there really isn't a good solution.

    So, I ask... What exactly can be done about the issue? What would be some of the best work arounds?

    Comprehensive list of Content access modules and how to enable them to work together

    I created a list of content permission modules that I have encountered with their weights on my system.

    1. Can we create a comprehensive list?
    2. How can they work together or should they. From your experience, what has been the worst and best combinations ?
    3. what effect does module weight have on implementation of access? is it true that if access is already granted, it will not be restricted by another module that comes into play later?

    Weight/ Name/ Version/ Brief description

    0 Content Permissions 6.x-2.x-dev Set field-level permissions for CCK fields.
