Support for authentication with Keystone v3 API

[bill_az]

I am using Cyberduck and am able to connect to OpenStack deployments that use keystone v2, but not keystone v3. Is keystone v3 api supported, and if not when is it expected?

[dkocher]

Reference in ​Identity API v3.

[dkocher]

​How do I migrate from v2.0 to v3.

[dkocher]

In ​New implementations to authenticate with OpenStack Identity API v3.

[dkocher]

You will need to create a custom ​connection profile with the authentication path /v3/tokens set in Context Path. Adapt from ​Openstack Swift (Keystone).cyberduckprofile.

[dkocher]

In r17511.

[bill_az]

@dkocher thanks for the fast reply. Is there a way to test with this code now? Or if not, when will v4.8 be available?

[dkocher]

Please update to the latest ​snapshot build available.

[dkocher]

Please confirm if this works as we haven't done any integration testing with a Keystone v3 deployment.

[dkocher]

New profile in r17553.

I would like to try the fix, but I am not able to find the build for this change. The latest nightly build for windows is Cyberduck-Installer-4.8.17726.exe, and by trying Preference ->Update ->Snapshot Builds it says "You're up to date!" with User-Agent: Cyberduck/4.8.17726 (Windows 7/6.1) (x86).

[dkocher]

There seems to be a confusion with naming the region in the response XML. We have taken an example from ​https://github.com/openstack/python-keystoneclient/blob/master/examples/pki/cms/auth_v3_token_scoped.json for a testcase where the field is named regionwhereas in the documentation at ​http://developer.openstack.org/api-ref-identity-v3.html the field is named region_id. The downside of all these JSON blobs with no validation that we would have for free with XML Schema.

[dkocher]

We can find no example at ​http://docs.openstack.org/developer/keystone/api_curl_examples.html with a object-store type in the service catalog result set.

[dkocher]

Revert support for v3 authentication and postpone to 4.8 in r17846.

[dkocher]

Can you provide a temporary integration testing environment?

[bill_az]

@dkocher - can we schedule a joint debug session? We can share screen/conference call to debug. If this works, let me know a day / time that would be convenient.

[bill_az]

@dkocher hi, still want to see if we can set up a meeting with shared screen to debug. Would that work? What time zone are you in?

[dkocher]

Replying to bill_az:

We are in UTC+1.

[dkocher]

Please try build r17986 or later.

[dkocher]

Is it possible for you to provide the HTTP response body (JSON formatted) the server sends possibly using the Swift command line tools?

Do other operations such as listing containers and keys succeed?

No other operation succeed, it is only possible to establish the connection.

[Falk Reimann]

Hi together,

Not sure about the current state of this. But besides the region, the profile should also contain an option to specify the used domain (ideally separating user domain and project domain).
The domain should be forwarded to ch.cyberduck.core.openstack.SwiftAuthenticationService were ch.iterate.openstack.swift.method.Authentication3UsernamePasswordProjectRequest is used without specifying the domain. So Authentication3UsernamePasswordProjectRequest is already able to handle domains I would assume.
This leads to the fact, that only projects in default domain are accessible. Having customers isolated by domain in keystone v3, is one benefit someone would use v3. Would you agree?

Many Thanks in advance,
Falk

[stenstad]

I would be more than happy to provide you with a test account for a public cloud with Openstack Swift and Identity v3 with domains and projects. Who should I send it to?

Hi. Great news. Would it be possible to have a nightly build with this fix included?

New snapshot builds will become available this week.

Version 4.8.0.18437 is now available as a snapshot build.

Hi. I did a quick check with Cyberduck connecting to a OpenStack devstack with keystone v3 enabled. It is still not working for me. I think the main issue is, that Cyberduck uses the UserID as Auth Token instead of the X-Subject-Token after issuing an token from keystone and therefore Swift will not authorize the request. I attached the main information from the log drawer. Can you please revisit this?
Thanks in advance, Falk

Token issued from keystone:

X-Subject-Token: 4c29d27f7c2e46b6bc82708d6060311b

Token provided to Swift:

X-Auth-Token: e239b9d1a16b4d6ea37770beabe06fea

User Id:

id: e239b9d1a16b4d6ea37770beabe06fea

Log Drawer output (truncated):

And the user details I used for connection:

The documentation ​documentation has to say

In v3, your token is returned to you in an X-Subject-Token header, instead of as part of the request body. You should still authenticate yourself to other services using the X-Auth-Token header.

Fix in ​upstream.

Many thanks for the quick response.
Just tested version 4.8.0 (18464) and keystone v3 does now work with the issued token against swift.
Great, Thanks, Falk
