Following the recent v3applicationcredentials patch, if you have your
environment variables set up to work with python-openstackclient using
swiftclient's v1password plugin, swiftclient won't work:
$ env | egrep '^(OS|ST)_'
ST_KEY=testing
ST_USER=test:tester
OS_AUTH_URL=http://saio/auth/v1.0
ST_AUTH=http://saio/auth/v1.0
OS_USERNAME=test:tester
OS_AUTH_TYPE=v1password
OS_PASSWORD=testing
$ openstack object store account show
+------------+----------------------------+
| Field | Value |
+------------+----------------------------+
| Account | AUTH_test |
| Bytes | 0 |
| Containers | 11 |
| Objects | 0 |
+------------+----------------------------+
$ swift stat
Only "v3applicationcredential" is supported for --os-auth-type
We don't really want to allow (and mostly ignore) arbitrary OS_AUTH_TYPE
values, though -- there are a whole bunch of plugins we don't remotely
support. But it seems OK to allow any of the password plugins; while we
won't actually use them (currently), we provide roughly equivalent
functionality.
Handful of other drive-bys:
* Use a None sentinel to determine whether keystoneauth1 is installed
instead of trying to catch a NameError.
* Clarify error state when keystoneauth1 is not installed.
* Fix a typo: "sses" -> "sess".
