mod_pubsub_post: Restructure authentication and authorization (BC) This deprecates the default "superuser" actor model and makes the default equivalent to the previous "request.id". A single actor and secret per node is supported because HTTP and WebHooks don't normally include any authorization identity. Allowing authentication bypass when no secret is given should be relatively safe when the actor is unprivileged, as will be unless explicitly configured otherwise.

summary: LDAP authentication module
...

Introduction
============

This is a Prosody authentication plugin which uses LDAP as the backend.

Dependecies
===========

This module depends on [LuaLDAP](http://www.keplerproject.org/lualdap/)
for connecting to an LDAP server.

Configuration
=============

Copy the module to the prosody modules/plugins directory.

In Prosody's configuration file, under the desired host section, add:

``` {.lua}
authentication = "ldap"
ldap_base = "ou=people,dc=example,dc=com"
```

Further LDAP options are:

  Name                  Description                                                                                                            Default value
  --------------------- ---------------------------------------------------------------------------------------------------------------------- --------------------
  ldap\_base            LDAP base directory which stores user accounts                                                                         **Required field**
  ldap\_server          Space-separated list of hostnames or IPs, optionally with port numbers (e.g. "localhost:8389")                         `"localhost"`
  ldap\_rootdn          The distinguished name to auth against                                                                                 `""` (anonymous)
  ldap\_password        Password for rootdn                                                                                                    `""`
  ldap\_filter          Search filter, with `$user` and `$host` substituted for user- and hostname                                             `"(uid=$user)"`
  ldap\_scope           Search scope. other values: "base" and "onelevel"                                                                      `"subtree"`
  ldap\_tls             Enable TLS (StartTLS) to connect to LDAP (can be true or false). The non-standard 'LDAPS' protocol is not supported.   `false`
  ldap\_mode            How passwords are validated.                                                                                           `"bind"`
  ldap\_admin\_filter   Search filter to match admins, works like ldap\_filter

**Note:** lua-ldap reads from `/etc/ldap/ldap.conf` and other files like
`~prosody/.ldaprc` if they exist. Users wanting to use a particular TLS
root certificate can specify it in the normal way using TLS\_CACERT in
the OpenLDAP config file.

Modes
=====

The `"getpasswd"` mode requires plain text access to passwords in LDAP
and feeds them into Prosodys authentication system. This enables more
secure authentication mechanisms but does not work for all deployments.

The `"bind"` mode performs an LDAP bind, does not require plain text
access to passwords but limits you to the PLAIN authentication
mechanism.

Compatibility
=============

Works with 0.8 and later.
