I am using Havana and trying to setup a controller node. When I execute ...

 # /usr/bin/keystone --os-username=admin --os-auth-url token-get
OS Password:

... I get this error:

Authorization Failed: An unexpected error prevented the server from fulfilling your request. Unable to parse connection string: "[""" (HTTP 500)

I believe I am using the correct password. I do not understand the error message I am getting. Any help is appreciated.


Update: Here's what I see in my configs ...

# cd /etc
# find . -exec grep "" {} \;
memcached_servers = ["", ""]
servers = ["", ""]
# find . -exec grep -l "" {} \;
