<p>This module was written to extend the standard functionality regarding users
and groups management by adding a new <cite>Backend user</cite> group that only gives access
to odoo backend (<cite>/web</cite>):</p>
<ul class="simple">
<li>minimal default access:
* users and partners (this is necessary to access your own data)
* mail activity, notification and channel
* presence</li>
<li>minimal default menu
* notification
* activities</li>
<li>minimal default access rules</li>
</ul>
<p>The problem with the <cite>Internal user</cite> is when you want to gives access to the
backend to a really thin part of your business to some users, its quite hard
to properly maintain those roles over the project life, a lot of models use
that group (<cite>base.group_user</cite>) by default which makes hard to maintains.</p>
<p>So that helps creating well-defined user groups with more controls.</p>
<p>This modules does 3 things:
* It hijack the has_group method of res.users by returning True for group_backend users when the requested group is group_user (The need for this needs to be investigated)
* It sets the res_users.share to False for group_backend users. This allows those users to access the backend.
* It sets the bare minimum permission in the ir.model.access.csv to display the backend</p>
<p>We suggest to use this module with its compagnon <cite>base_user_role</cite></p>
<p>Here is an example where a backend ui user can only access and use the dummy app. No other application are available to this user. You may define your own application instead of the dummy one.</p>

</div>
<div class="section" id="limitations">
<h1>Limitations</h1>
<p>At the time of writing, Odoo uses <cite>res.users.share == False</cite> to give the
backend access.
However to be able to access the backend without any errors some basic rights are necessary.
This module change the way <cite>res.users.share</cite> is computed to allow <cite>group_backend users</cite> to use the backend.</p>
<p>This avoids to write a lot of overwrite in different controllers from
different modules (portal, web, base, website) with hard coded statements
that check if user is part of the <cite>base.group_user</cite> or <cite>share == False</cite> group.</p>

<p>To allow <cite>group_backend</cite> to interact with a model you can either add access rules to the group

<div class="admonition note">

<p class="last">Be aware users can only belong to one group from the user type category

<p>To use this module, you need to:</p>
<ol class="arabic simple">
<li>Go to Configuration / Users / Users, choose a user and set the user type.</li>
</ol>
<p>You get a users that is only able to access to the Odoo backend which you
can attach other groups that not implies other kind of users (<cite>portal</cite>,
<cite>internal users</cite>)</p>
