Pull Request Overview
This PR adds an optional internal OpenLDAP server to replace the built-in RocksDB-based IDM, enabling horizontal scaling and serving as a prerequisite for HA.
- Introduces new
ldap.internalvalues and defaults invalues.yaml - Adds Helm templates (Service, Secret, PVC, Deployment, ConfigMap, helper) for an OpenLDAP instance
- Integrates internal LDAP into the main deployment, updates environment variables, README, and bumps chart version
Comments suppressed due to low confidence (2)
charts/opencloud/templates/openldap/secrets.yaml:7
- [nitpick] Consider adding the common chart labels using
{{ include "opencloud.labels" . | nindent 4 }}above this line so that the Secret has consistent release and chart metadata like other resources.
app.kubernetes.io/component: openldap
charts/opencloud/README.md:385
- The documentation claims a random password is generated, but the chart uses a fixed default (
adminpass). Update the docs to reflect actual behavior or implement random password generation.
> If not set, a random password is generated during installation and stored in a Helm-managed secret. This secret uses the annotation `helm.sh/resource-policy: keep` to prevent it from being overwritten on upgrade.

Using a hardcoded default password is insecure. Consider removing the static default or generating a strong random password at install time to prevent accidental exposure.

This PR introduces a new internal ldap server based on bitnami/openldap. It replaces the built in LDAP opencloud server (idm) when
ldap.internat.enabled: true.The built in LDAP server is based on rocksdb and cannot scale horizontally. The internal openldap server at least allows scaling it individually.
In a subsequent PR we can introduce
ldap.externalto use an external ldap server, eg. 389DS or an ldap cluster if necessary.This PR is also a prerequisite for HA of multiple openldap pods.
