# Use LDAP permissions in PostgreSQL
|
|
|
|
* http://github.com/larskanis/pg-ldap-sync
|
|
|
|
## DESCRIPTION:
|
|
|
|
LDAP is often used for 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 direct authorization of database users on LDAP.
|
|
So roles and memberships has to be administered twice.
|
|
|
|
This program helps to solve the issue by synchronizing users, groups and their memberships from LDAP to PostgreSQL.
|
|
Access to LDAP is used read-only.
|
|
`pg_ldap_sync` issues proper CREATE ROLE, DROP ROLE, GRANT and REVOKE commands to synchronize users and groups.
|
|
|
|
It is meant to be started as a cron job.
|
|
|
|
## FEATURES:
|
|
|
|
* Configurable per YAML config file
|
|
* Can use Active Directory as LDAP-Server
|
|
* Nested groups/roles supported
|
|
* Set scope of considered users/groups on LDAP and PG side
|
|
* Runs with pg.gem (C-library) or postgres-pr.gem (pure Ruby)
|
|
* Test mode which doesn't do any changes to the DBMS
|
|
* Both LDAP and PG connections can be secured by SSL/TLS
|
|
|
|
## REQUIREMENTS:
|
|
|
|
* Ruby-2.0+, JRuby-1.2, Rubinius-1.2 or better
|
|
* LDAP-v3 server
|
|
* PostgreSQL-server v9.0+
|
|
|
|
## INSTALL:
|
|
|
|
Install Ruby:
|
|
|
|
* on Windows: http://rubyinstaller.org
|
|
* on Debian/Ubuntu: `apt-get install ruby libpq-dev`
|
|
|
|
Install pg-ldap-sync and required dependencies:
|
|
```sh
|
|
gem install pg-ldap-sync
|
|
```
|
|
|
|
### Install from Git:
|
|
```sh
|
|
git clone https://github.com/larskanis/pg-ldap-sync.git
|
|
cd pg-ldap-sync
|
|
bundle
|
|
rake install
|
|
```
|
|
|
|
## USAGE:
|
|
|
|
Create a config file based on
|
|
[config/sample-config.yaml](https://github.com/larskanis/pg-ldap-sync/blob/master/config/sample-config.yaml)
|
|
or even better
|
|
[config/sample-config2.yaml](https://github.com/larskanis/pg-ldap-sync/blob/master/config/sample-config2.yaml)
|
|
|
|
Run in test-mode:
|
|
```sh
|
|
pg_ldap_sync -c my_config.yaml -vv -t
|
|
```
|
|
Run in modify-mode:
|
|
```sh
|
|
pg_ldap_sync -c my_config.yaml -vv
|
|
```
|
|
|
|
## TEST:
|
|
There is a small test suite in the `test` directory that runs against an internal ruby-ldapserver and PostgreSQL server. Ensure gem `ruby-ldapserver` is installed and `pg_ctl`, `initdb` and `psql` commands are in the `PATH`. Then:
|
|
```sh
|
|
cd pg-ldap-sync
|
|
rake test
|
|
```
|
|
|
|
## ISSUES:
|
|
|
|
* There is currently no way to set certain user attributes in PG based on individual attributes in LDAP (expiration date etc.)
