python-keystone 2012.1+stable~20120824-a16a0ab9-0ubuntu2.4 improperly pulled in patch from upstream

[Ryan Lane]

The configuration option is missing in: /usr/lib/python2.7/dist-packages/keystone/config.py

This leads to a completely broken keystone:

I am not seeing this:
$ dpkg -l|grep python-keystone
ii python-keystone 2012.1+stable~20120824-a16a0ab9-0ubuntu2.4 OpenStack identity service - Python library

$ grep max_param_size /usr/lib/python2.7/dist-packages/keystone/config.py
register_int('max_param_size', default=64)

In testing I also tried authenticating the with no changes to /etc/keystone/keystone.conf:
$ nova keypair-list
+-------+-------------------------------------------------+
| Name | Fingerprint |
+-------+-------------------------------------------------+
| mykey | ad:4f:2a:d2:c1:3f:8b:c0:e6:3f:de:cd:48:8d:fe:08 |
+-------+-------------------------------------------------+

and also with using in the [DEFAULTS] section of /etc/keystone/keystone.conf (and restarting keystone):
max_param_size = 4

$ nova keypair-list
ERROR: Request attribute username must be less than or equal to 4. The server could not comply with the request because the attribute size is invalid (too large). The client is assumed to be in error. (HTTP 400)

Can you provide the exact steps on how to reproduce along with your /etc/keystone/keystone.conf (redacting any passwords or otherwise sensitive information)?

Seems a fresh install works properly. A package upgrade caused this state for me.

[Ryan Lane (rlane)]

Tracked it down. Our configuration management system was applying patches that applied to an older version of python-keystone and were breaking this version. Sorry for the confusion!

Thanks for follow-up. :)
