# Keycloak

These guides cover **Keycloak as the OpenG2P applications' identity provider** — the per-environment Keycloak installed by the environment stage (part of commons). It issues OIDC clients, realms, and user accounts for the OpenG2P modules (Registry, PBMS, SPAR, eSignet, the Staff Portal, etc.).

{% hint style="info" %}
**This is the apps' IdP, not Rancher's login.** Rancher (the cluster-management UI) uses **local authentication** — its admin users are created directly in Rancher, with no SSO. There is one Keycloak **per environment**, reached at `keycloak.<environment-domain>`.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.openg2p.org/operations/deployment/deployment-guide/keycloak.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
