edx-platform - Activation link when registering account from CMS after 05/16/2014 update

This morning, after I ran an update for our Open edX instance, the activation link when registering from CMS was 'localhost' even though the EDXAPP_SITE_NAME variable was set to 'our.domain.com'.

After a while looking around the ansible playbooks of the configuration repo, I figured out why. There were some changes with the main configuration file which caused the issue:

https://github.com/edx/configuration/blob/master/playbooks/roles/edxapp/defaults/main.yml

They are:

EDXAPP_SITE_NAME: 'localhost'

EDXAPP_LMS_SITE_NAME: "{{ EDXAPP_SITE_NAME }}"

EDXAPP_CMS_SITE_NAME: 'localhost'

So, I had to add EDXAPP_CMS_SITE_NAME variable in /edx/app/edx_ansible/server-vars.yml and ran the update script again:

EDXAPP_SITE_NAME: 'our.domain.com'

EDXAPP_CMS_SITE_NAME: 'our.domain.com'

For now, the EDXAPP_CMS_SITE_NAME have to be the same with EDXAPP_SITE_NAME or the activation link will not work.
