PostgreSQL permissions

PostgreSQL roles versus users, grant permissionsFinding AD group permissions sourceGrant permissions on stored procedureDefault connect rightsDeny dbo schema permissionpostgres 9.1: role public does not existHow can I grant permissions on tables created in the future to members of a particular role?Setting up a simple “permissions architecture” in PostgreSQLPostgreSQL - Grant privileges as superuserSQL Server database level roles for creating tables

1

I'm trying to achieve a simple architecture:

1. An organization has many users


2. A user belongs to many organizations


3. A user can connect


4. A user can join and leave an organization


5. A user can read-only tables granted to organizations

First, securing permissions, as recommended in many places (https://ankane.org/postgres-users, https://marcyes.com/2016/0922-messing-with-postgresql-users-and-permissions/)

REVOKE ALL ON DATABASE stamped_development FROM PUBLIC;

REVOKE ALL ON SCHEMA public FROM PUBLIC;

Then, creating an organizations role with read permissions:

CREATE ROLE organizations;

GRANT USAGE ON SCHEMA public TO organizations;

GRANT SELECT ON ALL TABLES in SCHEMA public TO organizations;

Then, creating a users role with connect permissions:

CREATE ROLE users WITH LOGIN;

GRANT CONNECT ON DATABASE stamped_development TO users;

Create an organization and a user:

CREATE ROLE org_123 IN ROLE organizations;

CREATE ROLE user_123 WITH NOINHERIT ENCRYPTED PASSWORD 'secret' IN ROLE users;

Joining and leaving organizations as a user:

GRANT org_123 TO user_123;

REVOKE org_123 FROM user_123;

Problems:

• 
  psql -U user_123 -w secret fails with: role "user_123" is not permitted to log in
  


• at some point I've been able to login, but couldn't read tables

Any thoughts on what's missing?

You created user_123 with the noinherit option, which means that none of the privileges granted to the role users (in which you created user_123) applies to the new role.

And the organization role org_123 also does not have the connect privilege, so your user does not have any connect privilege at all.

You want:

CREATE ROLE user_123 WITH PASSWORD 'secret' IN ROLE users;

That way all privileges from users are granted to role user_123
