After a full debugging session, it seems that the problem was because kevin and Tom had user_name instead of user_id for the user_id field. This seems to come from the keystone command line as when creating new ec2 credentials --user is more likely to be a username when this should be a user-id.
I would vote to rename this to --user-id for RC2 as this can be a real pain (more a pain than renaming the docs, fix devstac etc..)
