Comment 3 for bug 1101129

from the looks of it, the config file is properly found and parsed using the '--config-dir' parameter. the issue is that the keystone-all script checks that CONF.config_file is set -- CONF.config_file is not set in the case where conf file is read via '--config-dir' parameter.

i think the fix needs to to be done in openstack.common code but i'm not sure what the protocol for modify code in there is (still new to openstack but i assume its shared code across projects based on its name).
