Comment 3 for bug 860885

This is what see in keystone conf file present in repo
sql_connection = sqlite:///keystone.db

This is what I see in the doc.

SQLite connects to file based databases. The same URL format is used, omitting the hostname, and using the “file” portion as the filename of the database. This has the effect of four slashes being present for an absolute file path:

# sqlite://<nohostname>/<path>
# where <path> is relative:
sqlite_db = create_engine('sqlite:///foo.db') => Three slashes

So I would assume that we dont need to change anything on keystone.
