Dex IdP custom token claims from Postgres

Consider a multi-tenant SaaS app. After login, your app still needs to know:

  • which org is this user in
  • what's their role
  • are they on a paid plan
  • ... ...

And users may authenticate through different connectors (password, LDAP, external IdP) - the token needs consistent user context regardless.

This post covers a Dex fork that enriches issued tokens with custom claims - statically or from a Postgres query.
