-- `openondemand_auth` and any corresponding options.

-- `openondemand_host_regex` if `openondemand_desktop` or `openondemand_jupyter` inventory groups are defined and/or proxying Grafana via Open Ondemand is required.
+The following variables have been given default values to allow Open Ondemand to work in a newly created environment without additional configuration, but generally should be overridden in `environment/site/inventory/group_vars/all/` with site-specific values:
+- `openondemand_servername` - this must be defined for both `openondemand` and `grafana` hosts (when Grafana is enabled). Default is `ansible_host` (i.e. the IP address) of the first host in the `openondemand` group.
+- `openondemand_auth` and any corresponding options. Defaults to `basic_pam`.
+- `openondemand_desktop_partition` and `openondemand_jupyter_partition` if the corresponding inventory groups are defined. Defaults to the first compute group defined in the `compute` Terraform variable in `environments/$ENV/terraform`.

 The appliance automatically configures Open Ondemand to proxy Grafana and adds a link to it on the Open Ondemand dashboard. This means no external IP (or SSH proxying etc) is required to access Grafana (which by default is deployed on the control node). To allow users to authenticate to Grafana, the simplest option is to enable anonymous (View-only) login by setting `grafana_auth_anonymous` (see [environments/common/inventory/group_vars/all/grafana.yml](../environments/common/inventory/group_vars/all/grafana.yml)[^1]).
 
 [^1]: Note that if `openondemand_auth` is `basic_pam` and anonymous Grafana login is enabled, the appliance will (by default) configure Open Ondemand's Apache server to remove the Authorisation header from proxying of all `node/` addresses. This is done as otherwise Grafana tries to use this header to authenticate, which fails with the default configuration where only the admin Grafana user `grafana` is created. Note that the removal of this header in this configuration means it cannot be used to authenticate proxied interactive applications - however the appliance-deployed remote desktop and Jupyter Notebook server applications use other authentication methods. An alternative if using `basic_pam` is not to enable anonymous Grafana login and to create Grafana users matching the local users (e.g. in `environments/<env>/hooks/post.yml`).
+
+# Access
+By default the appliance authenticates against OOD with basic auth through PAM. When creating a new environment, a new user with username `demo_user` will be created. Its password is found under `vault_openondemand_default_user` in the appliance secrets store in `environments/{ENV}/inventory/group_vars/all/secrets.yml`. Other users can be defined by overriding the `basic_users_users` variable in your environment (templated into `environments/{ENV}/inventory/group_vars/all/basic_users.yml` by default).
