= Use LDAP permissions in PostgreSQL

* Homepage: http://github.com/larskanis/pg-ldap-sync

== DESCRIPTION:

LDAP is often used to do a centralized user and role management
in an enterprise environment. PostgreSQL offers different
authentication methods, like LDAP, SSPI, GSSAPI or SSL.
However, for any method the user must already exist in the database,
before the authentication can be used. There is currently
no authorization of database users directly based on LDAP.

This program solves the issue by synchronizing users, groups and
memberships from LDAP to PostgreSQL.
It is meant to be started as a cron job.

== FEATURES/PROBLEMS:

* Configurable per YAML config file
* Use Active Directory as LDAP-Server
* Runs with pg.gem (C-library) or postgres-pr.gem (pure Ruby)
* Should run on any platform when using postgres-pr.gem

* There is currently no way to set certain user attributes in PG
  based on individual attributes in LDAP

== SYNOPSIS:

Create a config file based on <tt>config/sample-config.yaml</tt> .

  pg_ldap_sync -c my_config.yaml -vv -t

== REQUIREMENTS:

* Installed Ruby and rubygems
* LDAP- and PostgreSQL-Server

== INSTALL:

Install Ruby and rubygems:
* on Windows: http://rubyinstaller.org
* on Debian: <tt>apt-get install ruby rubygems</tt>

Install pg-ldap-sync and a database driver for PostgreSQL:
* <tt>gem install pg-ldap-sync pg</tt>
* or <tt>gem install pg-ldap-sync postgres-pr</tt> for the
  pure ruby version with less connection options than <tt>pg</tt>

Or install from Git:
  git clone https://github.com/larskanis/pg-ldap-sync.git
  cd pg-ldap-sync
  rake install_gem

== TEST:
There is a small test suite in the <tt>test</tt> directory that runs
against an internal ruby-ldapserver and PostgreSQL server. Ensure gem
<tt>ruby-ldapserver</tt> is installed and <tt>pg_ctl</tt>, <tt>initdb</tt> and <tt>psql</tt>
commands are in the <tt>PATH</tt>. Then:

  cd pg-ldap-sync
  rake test
