ldap2pg: PostgreSQL role and privileges management

Swiss-army knife to synchronize Postgres roles and privileges from YAML or LDAP.

Postgres is able to check password against an entreprise directory using the LDAP protocol out of the box. ldap2pg automates the creation, update and removal of PostgreSQL roles and users based on entreprise organigram described in the directory.

Managing roles is close to managing privileges as you expect roles to have proper default privileges. ldap2pg can grant and revoke privileges too.


  • Reads settings from an expressive YAML config file.
  • Creates, alters and drops PostgreSQL roles from LDAP searches.
  • Creates static roles from YAML to complete LDAP entries.
  • Manages role members (alias groups).
  • Grants or revokes privileges statically or from LDAP entries.
  • Dry run, check mode.
  • Logs LDAP searches as ldapsearch(1) commands.
  • Logs every SQL query.

Here is a sample configuration and execution:

$ cat ldap2pg.yml
- role:
    name: ldap_roles
    options: NOLOGIN
- ldapsearch:
    base: ou=people,dc=ldap,dc=ldap2pg,dc=docker
    filter: "(objectClass=organizationalPerson)"
    name: '{cn}'
    options: LOGIN
    parent: ldap_roles
$ ldap2pg --real
