<font face="Default Sans Serif,Verdana,Arial,Helvetica,sans-serif" size="2">Had the same issue when I worked on the context selection menu for switching domain and project. I think it make sense to rename it to AVAILABLE_KEYSTONE_ENDPOINTS. Since it is local_settings.py, its going to affect some folks (maybe even break) until they also update their setting, something that would have to be done manually.<br><br><font color="#990099">-----Jay Pipes <jaypipes@gmail.com> wrote: -----</font><div class="iNotesHistory" style="padding-left:5px;"><div style="padding-right:0px;padding-left:5px;border-left:solid black 2px;">To: openstack-dev@lists.openstack.org<br>From: Jay Pipes <jaypipes@gmail.com><br>Date: 07/08/2015 07:14AM<br>Subject: Re: [openstack-dev] [horizon] [keystone] [docs] Two kinds of 'region' entity: finding better names for them<br><br><div><font face="Courier New,Courier,monospace" size="3">Got it, thanks for the excellent explanation, Timur!
