Public bug reported:
When playing with some keystone deployment alternatives I stumble on a

Switching to UUID tokens it works. Switching to SQL Identity backend and
fernet tokens works.
The combination of LDAP identity backend and fernet tokens gives me the
above log for any request with name/password. Reproducable always.
I have a very minimalistic "cloud" setup with only 2 or 3 docker
containers. One with the SQL DB, one for Keystone and optionally one for
LDAP.
I use Ubuntu 15.04 as base image for my containers that includes Kilo.
I've patched keystone with the following changeset to make it work (with
LDAP):
