By default, Qpid uses TCP as a connection transport instead of connection protocol. Previously, the procedure for enabling SSL in Qpid connections, 'qpid_protocol = ssl' in /etc/glance/glance-api.conf, set the connection protocol. However, the python-qpid client 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.
