Link Landlord Profiles to OIDC Subjects

Status: superseded by ADR-0013

Context

ADR-0001 keeps the property portfolio shared and initially creates a default landlord. Connected accounts now need their own personal landlord profile for generated leases and rent receipts.

Decision

• A landlord profile is identified by the stable OIDC subject (sub) of its connected account.
• The e-mail address is a required, unique and mutable contact field; it is not the technical identifier.
• A connected account can read and update only its own landlord profile.
• This delivery does not partition apartments, leases or rent payments by account; the shared portfolio from ADR-0001 remains unchanged.

Consequences

The application must obtain the OIDC subject from the authenticated principal for every profile operation. A future move to separate portfolios remains a distinct migration and decision.
