Secure memcached installation for overcloud
Last modified: 2016-02-03 17:44:28 EST
Description of problem:
Memcached instances running at overcloud can be accessed by anyone who knows their ips
Version-Release number of selected component (if applicable):
Based on the project documentation SASL is the mechanism to use to secure the memcached instances.
The memcached package provided in base isn't compiled with SASL support, hence blocking this ticket.

This can't be fixed without significant work upstream in OpenStack. The following components in OpenStack use memcached:
None of these currently have support for using a SASL configured memcached. memcached explicitly disables non-SASL connections when it's running with SASL. Also, SASL support would require a new python library which we currently don't ship (python-binary-memcached) because the current python-memcached doesn't support binary mode.
Basically, to do this, we need to fix *each* of the above components to be able to use SASL auth with memcached (probably upstream).
