About | Usage | JSON Schema
This is a tiny helper utility that uses kanidm's API to provision users, groups and oauth2 systems. This tool is needed to allow declarative provisioning of kanidm in NixOS, but can be used on any other system as well. This tool is not affiliated with kanidm itself. Use at your own discretion.
Two optional patches are provided for kanidm that allow you to:
- provision oauth2 basic secrets
- use a specific password when recovering admin account credentials.
Currently this tool supports the following provisioning operations which should suffice for basic SSO and OIDC needs. PRs are of course welcome!

(*): Requires patch, see below.
Build the utility simply by running:
> cargo build
Afterwards you can apply a state file to your kanidm instance by executing:
KANIDM_PROVISION_IDM_ADMIN_TOKEN="your-idm-admin-token" \
kanidm-provision --url 'https://auth.example.com' --state state.json
This tool automatically adds all created entities to a tracking group so whenever something is removed from the state file in the future, the change can be reflected in kanidm automatically.
To prevent this kind of orphan removal, you can to pass --no-auto-remove
.
Removing for example a group from the state file will then not cause any
changes in kanidm, unless the state file explicitly specifies present: false
.
This automatic tracking does not work for oauth2 claim maps, since claim maps
are not a separate entity in kanidm. To work around that, each oauth2 resource server
has a removeOrphanedClaimMaps
option that will delete any claim maps on the resource
server that haven't been created by this tool. --no-auto-remove
has no effect on that option.
This tool is able to provision basic secrets if you build kanidm with the patch provided in ./patches. This adds a new endpoint that allows modifying the basic secret of any oauth2 resource server via a new API endpoint, instead of only allowing to read the value generated by kanidm.
Caution
You need to reset your kanidm database after applying this change, otherwise the access control profile will not be updated and any call to the new endpoint will fail!
The second provided patch is a standalone kanidm patch that adds the ability to specify a password when recovering account credentials. Useful to provision the idm_admin password and avoid dynamic state that needs to be known to run the provisioning tool.
KANIDM_RECOVER_ACCOUNT_PASSWORD=V3kACDdwPjYUgYuLdlRfBqeBWf3TyJmv9h0f6CP3E3dv2B4S \
kanidmd recover-account idm_admin --from-environment >/dev/null
