OpenLDAP

Installs OpenLDAP and phpLDAPadmin with a small number of initial users for the purposes of demonstrating LDAP integration capabilities of IBM Cloud Paks.

Forked from https://github.com/ibm-cloud-architecture/icp-openldap

Updated to work with new versions of Kubernetes (>=1.16.x)

Installation

To install the chart, you'll need the helm cli and the IBM Cloud Private CLI. Note: the IBM Cloud Private CLI version level must match the version level that is downloadable via your ICP console, under Menu > Command Line Tools > Cloud Private CLI.

1. Get the source code of the helm chart git clone https://github.com/dymaczew/cp-openldap.git
2. Package the helm chart using the helm cli helm package cp-openldap
3. If you have not, log in to your cluster from the IBM® Cloudak CLI and log in to the Docker private image registry. cloudctl login -a https://<cluster_domain> --skip-ssl-validation 4a. If you have Tiller available (CloudPak for MCM 1.3 or 2.0) install the Helm chart using helm v2 cli helm install --name ldap-slap --namespace kube-public --values cp-openldap/values.yaml --tls 4b. For other CloudPaks render the chart and apply using oc apply helm template --name ldap-slap --namespace kube-public --values cp-openldap/values.yaml | kubectl apply -f -
