By default, QPID uses TCP as a connection transport instead of connection protocol. Previously, the procedure for enabling SSL in QPID connections was to set 'qpid_protocol = ssl' in /etc/glance/glance-api.conf. This setting, however, sets connection protocol; the python-qpid client, on the other hand, expects a connection transport type. The mismatch prevented QPID from actually establishing an SSL connection.
With this release, the 'qpid_protocol = ssl' setting now enables SSL for the connection transport instead of connection protocol. As such, QPID can now successfully establish SSL connections.
