Hi, We are preparing something based on keystoneauth1 that uses an authorization code grant in OIDC that will send you an url address to the client so they can do the SSO there and receive a validation code. Then you input the validation code in the CLI and receive an OIDC.
Once it receives the OIDC access token and refresh token, we cache them on the filesystem for subsequent calls.
The idea was to contribute it upstream once we clean it up a bit
Cheers Jose

Would application credentials fit your use case for CLI access? Users will be able to create them through Horizon, and after creation they will be prompted to download either a clouds.yaml or an openrc file, so the process is pretty straightforward.

Can you elaborate more on your issue with not being able to grant roles to groups?

Hi Keystone users! I am wondering if anyone has experience with keystone openid integration. Initially I was using Keystone LDAP backend (using tripleo KeystoneLDAPDomainEnable and KeystoneLDAPBackendConfigs parameters) and it works! Users are able to log in through Horizon or through the cli, roles can be given per LDAP group, and you can click in Horizon and download a working openrc or clouds.yaml file (minus the root CA that has to be added) to authenticate with the cli (and your password ends as an OS_PASSWORD variable in your environment).
I am now trying the Keystone Openid backend (using the enable-federation-openidc.yaml provided by tripleo - https://github.com/openstack/tripleo-heat-templates/blob/master/environments... https://github.com/openstack/tripleo-heat-templates/blob/master/environments/enable-federation-openidc.yaml) with a mapping like this:
[{"local":[{"user":{"name":"{0}"},"group":{"domain":{"name":"Default"},"name":"federated_users"}}],"remote":[{"type":"HTTP_OIDC_EMAIL"}]}]
The SSO works superb with Horizon, however
- logging with the cli seems impractical. I see some doc here:
https://docs.ukcloud.com/articles/openstack/ostack-how-use-api-sso.html https://docs.ukcloud.com/articles/openstack/ostack-how-use-api-sso.html where you need to provide a secret, I am skeptical I want to do that. The openrc file downloaded from Horizon is not usable as is and needs some tuning. And there is no SSO, and the password still ends up in the environment...
- I don't see how I can grant roles to groups anymore. It seems I need
an extra mechanism to grant permissions (as I used to do that using LDAP groups).
I am wondering if anyone is willing to share their experience dealing with Keystone and OpenID.
Thanks! Francois (frigo)
