+# LDAP authentication
+
+To run manual tests with the default docker-compose files.
+
+Expose openldap container port by uncommenting the `ports` config in `docker-compose-ldap.yaml `
+
+To start openldap:
+
+```
+docker-compose -f ./.ci/docker-compose-file/docker-compose.yaml -f ./.ci/docker-compose-file/docker-compose-ldap.yaml up -docker
+```

+## LDAP database

+# disabled user
+mqttx pub -t 't/1' -h localhost -p 1883 -m x -u mqttuser0006 -P mqttuser0006
