[Ldap-auth](https://github.com/nginxinc/nginx-ldap-auth) software is for authenticating users who request protected resources from servers proxied by nginx. It includes a daemon (ldap-auth) that communicates with an authentication server, and a webserver daemon that generates an authentication cookie based on the user’s credentials. The daemons are written in Python for use with a Lightweight Directory Access Protocol (LDAP) authentication server (OpenLDAP or Microsoft Windows Active Directory 2003 and 2012).
Our images support multiple architectures such as `x86-64`, `arm64` and `armhf`. We utilise the docker manifest for multi-platform awareness. More information is available from docker [here](https://github.com/docker/distribution/blob/master/docs/spec/manifest-v2-2.md#manifest-list) and our announcement [here](https://blog.linuxserver.io/2019/02/21/the-lsio-pipeline-project/).
Docker images are configured using parameters passed at runtime (such as those above). These parameters are separated by a colon and indicate `<external>:<internal>` respectively. For example, `-p 8080:80` would expose port `80` from inside the container to be accessible from the host's IP on port `8080` outside the container.
| `FERNETKEY=` | Optionally define a custom fernet key, has to be base64-encoded 32-byte (only needed if container is frequently recreated, or if using multi-node setups, invalidating previous authentications) |
For all of our images we provide the ability to override the default umask settings for services started within the containers using the optional `-e UMASK=022` setting.
Keep in mind umask is not chmod it subtracts from permissions based on it's value it does not add. Please read up [here](https://en.wikipedia.org/wiki/Umask) before asking for support.
- This container itself does not have any settings and it relies on the pertinent information passed through in http headers of incoming requests. Make sure that your webserver is set up with the right config.
- Here's a sample config: [nginx-ldap-auth.conf](https://github.com/nginxinc/nginx-ldap-auth/blob/master/nginx-ldap-auth.conf).
- Unlike the upstream project, this image encodes the cookie information with fernet, using a randomly generated key during container creation (or optionally user defined).
- Also unlike the upstream project, this image serves the login page at `/ldaplogin` (as well as `/login`) to prevent clashes with reverse proxied apps that may also use `/login` for their internal auth.

We publish various [Docker Mods](https://github.com/linuxserver/docker-mods) to enable additional functionality within the containers. The list of Mods available for this image (if any) as well as universal mods that can be applied to any one of our images can be accessed via the dynamic badges above.
