1. Create a ConfigMap containing the IdM certificate to trust:
~~~
oc create configmap ca-config-map -n openshift-config --from-file=ca.crt
~~~

2. Configure the oauth/cluster object with configuration like below:
~~~
- name: ldapidp
    mappingMethod: claim
    type: LDAP
    ldap:
      attributes:
        id:
        - dn
        email:
        - mail
        name:
        - cn
        preferredUsername:
        - uid
      bindDN: "uid=admin,cn=users,cn=accounts,dc=ocp4,dc=example,dc=com"
      bindPassword:
        name: ldap-secret
      ca:
        name: ca-config-map
      insecure: false
      url: "ldap://idm.ocp4.example.com:389/cn=users,cn=accounts,dc=ocp4,dc=example,dc=com?uid" 

oc apply -f ldap-cr.yml
~~~

3. Login with the ldap user
~~~
oc login -u openshift-user -p openshift-user 

Login successful.

You don't have any projects. You can try to create a new project, by running    oc new-project <projectname>
~~~

The user logged in using secure LDAP.

The LDAP login should fail as the LDAP url setup in oauth/cluster is defined with port 389 which is not being connected

Based on the oauth/cluster object configuration anyone looking at will think that it is configured to connect via non-secure port, but this is not correct.
It is using secure port 636 to query LDAP and this is creating confusion.
This type of configuration should be invalidated at first place if the customer is setting `insecure: false` and using non-secure ldap url.
