mod_auth_ldap
An authentication provider which uses LDAP as the backend.
Dependencies
This module depends on LuaLDAP for connecting to an LDAP server.
Configuration
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" |
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
This module was added in Prosody 0.12. For earlier Prosody versions you can find it in the prosody-modules community repository.
