Short Description
LDAP service using OpenLDAP with the configuration provided in an environment variable
Full Description

LDAP service

This is a Dockerfile for an ldap service where the full slapd.conf is stored in an environment variable called LDAP_CONF.
Optional environment variables: SSL_KEY, SSL_CERT, SSL_CA_CERTS, LDIF_SEED_URL and LDIF_SEED_SUFFIX.

The optional LDIF_SEED_URL is a URL to a file containing LDIF entries created by slapcat. It can be any URL known to curl - including file:.
The file will be loaded before the LDAP daemon is started.

The optional LDIF_SEED_SUFFIX is useful in the case of having multiple backend databases in the slapd.conf file. It will be used to determine which database to add entries to.
