<p class="MsoNormal">Hi team,<o:p></o:p></p>
<div>
<p class="MsoNormal"><o:p> </o:p></p>
</div>
<div>
<p class="MsoNormal">I'm wondering if it makes sense for us to make a change in all of OpenStack Helm's code in order to make it use the service user for all requests.<o:p></o:p></p>
</div>
<div>
<p class="MsoNormal"><o:p> </o:p></p>
</div>
<div>
<p class="MsoNormal">For example, right now, we are using the placement user in the `[placement]` section in Neutron, or the Neutron user in the `[neutron]` section in Nova. However, all of these users have the same<o:p></o:p></p>
</div>
<div>
<p class="MsoNormal">exact role and permissions, so I believe it would help a lot in locking down services (let's say placement gets compromised, you can lock it's user only).<o:p></o:p></p>
</div>
<div>
<p class="MsoNormal"><o:p> </o:p></p>
</div>
<div>
<p class="MsoNormal">I also think it will significantly simplify all of our code for endpoints for the different services, since we'll just be re-using the same credentials.<o:p></o:p></p>
</div>

<p class="MsoNormal">Let me know what everyone thinks.<o:p></o:p></p>
