LDAP Toolbox - Self-Service-Password

Originally developed by "LTB-Project"

A PHP-based web-application (running on an Apache Webserver) that allows users to change their password in an LDAP directory. The application is developed by the LTB-Project (see http://ltb-project.org/wiki/documentation/self-service-password).

Configuration is performed automatically during each start-up to link to the appropriate LDAP- and/or Mail-Containers.

NOTE: On purpose, there is no secured channel (TLS/SSL) to the OpenLDAP-Server, because its service will never be exposed to the world.

Requirements

• Docker (>= 1.9.0)
• OpenLDAP-Server (required)
• Mail-Server (optional)

Provided Resouces

The service provides the following network ports and filesystems.

Exposed Ports

• 80 : Web-Server (unsecure)

Exposed Filesystems

None

Usage

The created container is configured automatically by the entrypoint-script during each run.

During this each run the following environment variables are evaluated:

General Variables:

• SERVER_HOSTNAME (default: ${HOSTNAME})
  • Override the default-hostname used in mails and web-interface

LDAP Self-Service-Password (optional):

• LSSP_ATTR_LOGIN (default: uid)
  • LDAP attribute for "Login"-Name
• LSSP_ATTR_FN (default: cn)
  • LDAP attribute for user's full name
• LSSP_ATTR_MAIL (default: mail)
  • LDAP attribute for user's mail address (required for password-reset support)
• LSSP_DEFAULT_ACTION (default: change)
  • LSSP default action for changing password (supported are change, sendtoken or sendsms)

OpenLDAP-Server (required):

• LDAP_BASE (default: empty)
  • LDAP-Domain to search for user-entries
  • Provide in dotted (.) notation (i.e. domain.com)
• LDAP_HOST (default: empty)
  • LDAP-Server's hostname or IP-address
• LDAP_PORT (default: 389)
  • LDAP-Server's port
• LDAP_USER (default: cn=admin,${LDAP_BASE})
  • Complete DN of the admin user, which is allowed to change user passwords.
• LDAP_PASS
  • Password of the admin user

Mail-Server (optional):

If SMTP_HOST is not set, Password-Reset via Mail-Tokens will be disabled in the Web-Interface! If either SMTP_USER or SMTP_PASS are empty, SMTP connects without user credentials!

• SMTP_HOST (default: empty)
  • Mail-Server's hostname or IP-address
• SMTP_PORT (default: 25)
  • Mail-Server's port
• SMTP_USER (default: empty)
  • Username for sender's mail-account
  • If omitted, authentication is disabled
• SMTP_PASS (default: empty)
  • Password for sender's mail-account
  • If omitted, authentication is disabled
• SMTP_FROM (default: root(at)${SERVER_HOSTNAME})
  • The address from which the password notification is coming from
• SMTP_TLS (default: off)
  • Enable TLS connection
  • Possible Values:
    • on: Enable TLS
    • off: Disable TLS

reCAPTCHA (optional):

• RECAPTCHA_USE (default: false)
  • Activate reCAPTCHA feature
• RECAPTCHA_PUB_KEY (default: empty)
  • reCAPTCHA public key
• RECAPTCHA_PRV_KEY (default: empty)
  • reCAPTCHA private key
• RECAPTCHA_SSL (default: false)
  • Enable TLS
• RECAPTCHA_THEME (default: white)
  • Choose theme

Link to a supported LDAP-Container

If you have a running OpenLDAP container of the following types

• dtwardow/openldap
• dinkel/openldap

you can link those containers directly using the link-alias ldap which will provide the following environment variables automatically

• LDAP_HOST (by Docker Environment)
• LDAP_PORT (by Docker Environment)
• LDAP_USER
• LDAP_PASS
• LDAP_BASE

Link to a supported Mail-Server Container

If you have running Mail-Server inside a container, you can link such a container directly using the link-alias mail. This will provide the following environment variables:

• SMTP_HOST (by Docker Environment)
• SMTP_PORT (by Docker Environment)

Advance configuration

If you want to override configuration you can mount volume for /usr/share/self-service-password/conf/conf.d and put your conf.php in it.

Password policy

Put this file in local lssp.d directory:

ppolicy.php

<?php
$pwd_min_length = 4;
$pwd_max_length = 24;

$pwd_min_lower = 3;
$pwd_min_upper = 1;
$pwd_min_digit = 1;
$pwd_min_special = 1;

$pwd_special_chars = "^a-zA-Z0-9";
$pwd_complexity = 4;

$pwd_no_reuse = true;

$pwd_show_policy = "always";
?>

Then run your container with --volume ./lssp.d:/usr/share/self-service-password/conf/conf.d.

Start-Up

You can run a container without linked containers:

docker run -d -p 8080:80
-e LDAP_HOST=<ldap-server-hostname>
-e LDAP_PORT=389
-e LDAP_BASE=example.com
-e LDAP_USER=<admin-username>
-e LDAP_PASS=<admin-password>
-e SMTP_HOST=<mailserver-hostname>
[-e SMTP_PORT=25]
[-e SMTP_USER=<smtp-username>]
[-e SMTP_PASS=<smtp-password>]
[-e SMTP_TLS=on]
[[-h <hostname>] | [-e SERVER_HOSTNAME=<hostname>]]
dtwardow/ldap-self-service-password:<tag>

Or with linked LDAP and Mail-Containers

docker run -d -p 8080:80
--link <ldap-server-container>:ldap
--link <mail-server-container>:mail
[-e SMTP_USER=<smtp-username>]
[-e SMTP_PASS=<smtp-password>]
[-e SMTP_TLS=on]
[[-h <hostname>] | [-e SERVER_HOSTNAME=<hostname>]]
dtwardow/ldap-self-service-password:<tag>

The examples above expose service on port 8080, so you can point your browser to http://hostname:8765/ in order to change or reset LDAP passwords.
