# For LDAPS with certificate validation:
# How to extract the TLS certificate from the OpenLDAP container, and encode it for the Dex config (`rootCAData`):
#   $ docker-compose exec ldap cat /container/run/service/slapd/assets/certs/ca.crt | base64 -w 0
# But note this issue: https://github.com/osixia/docker-openldap/issues/506
