 Fork of Nick Stenning docker-slapd :
 https://github.com/nickstenning/docker-slapd
+
+Add support of tls.
+
+### How to use tls
+
+Add `-v some/host/dir:/etc/ldap/ssl` and `--dns=127.0.0.1` to the run command.
+
+`some/host/dir` must contain a least 3 files :
+- `ca.crt` certificate authority certificate
+- `ldap.crt` ldap server certificate
+- `ldap.key` ldap server certificate private key
+
+and optionaly `dhparam.pem` this file is genereted automaticaly if not present.
+
+`--dns=127.0.0.1` allow to use the certificate cn correctly.
+
+
+### Example
+
+    docker run --dns=127.0.0.1 \
+               -v /data/ldap/db:/var/lib/ldap \
+               -v /data/ldap/config:/etc/ldap/slapd.d \
+               -v /data/ldap/ssl/:/etc/ldap/ssl \
+               -v /data/ldap/log/:/var/log \
+               -e LDAP_DOMAIN=example.com \
+               -e LDAP_ORGANISATION="Example Corp." \
+               -e LDAP_ROOTPASS=toor \
+               -p 389:389 -d osixia/openldap
