This will build a Docker Image LemonLDAP::NG an elegant web based manager for Authentication (SAML, OpenID Connect, CAS) served by Nginx.
- Sane defaults to have a working solution by just running the image
- Automatically generates configuration files on startup, or option to use your own
- Option to just use image as a Handler for external servers
- Handler Option to use file base socket or listen on TCP
- Fail2ban Included for blocking brute force attacks.
- Ready to work out the box for SAML, OpenID, 2FA/2OTP
- Additional modules compiled for Redis, Mysql, Postgres, LDAP Session/Config Storage
- Choice of Logging (Console, File, Syslog)
This is an incredibly complex piece of software and this image tries to get you up and running with sane defaults, you will need to switch eventually over to manually configuring the configuration file when depending on your usage case

- Assumes you are using some sort of SSL terminating reverse proxy such as:
- You must have access to create records on your DNS server to be able to setup the demo installation before configuration.
Clone this repository and build the image with docker build -t (imagename) .
Builds of the image are available on Docker Hub
docker pull docker.io/tiredofdit/lemonldap:(imagetag)
Builds of the image are also available on the Github Container Registry
docker pull ghcr.io/tiredofit/docker-lemonldap:(imagetag)
The following image tags are available along with their tagged release based on what's written in the Changelog:
Version | Container OS | Tag |
---|---|---|
latest | Alpine | :latest |
2.0.x | Alpine | 2.0-latest |
- The quickest way to get started is using docker-compose. See the examples folder for a working docker-compose.yml that can be modified for development or production use.
- If you'd like to just use it in Handler mode, you will find another sample docker-compose.yml file that should get you started.
- Add records for your main, and manager names into DNS (ie
handler.sso.example.com
.api.manager.sso.example.com
,manager.sso.example.com
,sso.example.com
,test.sso.example.com
) - Set various environment variables to understand the capabilities of this image. A Sample
docker-compose.yml
is provided that will work right out of the box for most people without any fancy optimizations. - Map persistent storage for access to configuration and data files for backup.
- Once run, visit the Manager URL and login as
dwho/dwho
The following directories should be mapped for persistent storage in order to utilize the container effectively.
Folder | Description |
---|---|
/etc/lemonldap-ng/ |
(Optional) - LemonLDAP core configuration files. Auto Generates on Container startup |
/var/lib/lemonldap-ng/conf |
Actual Configuration of LemonLDAP (lmConf-X.js files) |
/var/lib/lemonldap-ng/sessions |
(Optional) - Storage of Sessions of users |
/var/lib/lemonldap-ng/psessions |
(Optional) - Storage of Sessions of users |
/assets/custom |
Ability to overwrite themes/inject into image upon bootup for theming /etc. |
/www/logs |
Log files for individual services |
This image relies on an Alpine Linux base image that relies on an init system for added capabilities. Outgoing SMTP capabilities are handlded via msmtp
. Individual container performance monitoring is performed by zabbix-agent. Additional tools include: bash
,curl
,less
,logrotate
, nano
,vim
.
Be sure to view the following repositories to understand all the customizable options:

There are a huge amount of configuration variables and it is recommended that you get comfortable for a few hours with the LemonLDAP::NG Documentation
You will eventually based on your usage case switch over to SETUP_TYPE=MANUAL
and edit your own lemonldap-ng.ini
. While I've tried to make this as easy to use as possible, once in production you'll find much better success with large implementations with this approach.
By Default this image is ready to run out of the box, without having to alter any of the settings with the exception of the _HOSTNAME
vars. You can also change the majority of these settings from within the Manager. There are instances where these variables would want to be set if you are running multiple handlers or need to enforce a Global Setting for one specific installation.
Parameter | Description | Default |
---|---|---|

FALSE |

- With impersonation, if you enable it, it will add a new field to your login screen, which may not be what you want if this is a production system. You will need to create two custom themes (one as a replica of bootstrap, and one for impersonation). In the custom theme, make modifications to
login.tpl
to stop it from loading impersonation.tpl, yet in your impersonation theme, leave it in there. Then, when one of your admin/support team visits the customIMPERSONATE_HOSTNAME
you have defined it will load the full theme with allows to impersonate, where as the default theme will not show this.
