I'm trying to get my existing Guacamole installation working with OpenID.
I've got everything working correctly, but Guacamole is not requesting the
`groups` scope.
Here is the relevant environment variables from my docker-compose.yml:
```
environment:
- GUACD_HOSTNAME=${COMPOSE_PROJECT_NAME}-guacd-1
- POSTGRESQL_HOSTNAME=${COMPOSE_PROJECT_NAME}-postgres-1
- POSTGRESQL_DATABASE=postgres
- POSTGRESQL_USER=postgres
- POSTGRESQL_PASSWORD=postgres
- POSTGRESQL_AUTO_CREATE_ACCOUNTS=true
- OPENID_AUTHORIZATION_ENDPOINT=https://auth.
${HOMELAB_BASE_DOMAIN}/api/oidc/authorization?state=1234abcedfdhf
- OPENID_JWKS_ENDPOINT=https://auth.${HOMELAB_BASE_DOMAIN}/jwks.json
- OPENID_ISSUER=https://auth.${HOMELAB_BASE_DOMAIN}
- OPENID_CLIENT_ID=guacamole
- OPENID_REDIRECT_URI=https://remote-desktop-gateway.
${HOMELAB_BASE_DOMAIN}
- OPENID_USERNAME_CLAIM_TYPE=preferred_username
- OPENID_GROUPS_CLAIM_TYPE=groups
- OPENID_SCOPE=openid profile groups email
```
You can see the last line is setting `OPENID_SCOPE`, however, the generated
`guacamole.properties` does not contain `openid-scope`:
```
guacamole@78282607ee6c:/opt/guacamole$ cat
/home/guacamole/.guacamole/guacamole.properties
# guacamole.properties - generated Thu Feb 8 07:05:31 AM UTC 2024

openid-client-id: guacamole
openid-redirect-uri: https://remote-desktop-gateway. example.com
openid-username-claim-type: preferred_username
openid-groups-claim-type: groups
```
If I do manually edit the URL of the page I'm logging in with to add
`email` to the `scope` query parameter, groups are properly detected when
logging in. Without this, OpenID is a little hamstrung.
