User Lookup by External ID

[db-ot]

Userstory

As a system integrator, I want to look up users by an external ID so that de-provisioning works reliably with the identifiers known in the customer’s system.

Description

For proper de-provisioning, the system must support looking up users based on an external ID, as this is the only unique identifier available from the customer’s identity provider. The Microsoft Graph API already provides an externalId attribute. Our APIs currently do not support this attribute, so it must be added.

Acceptance Criteria

• System supports storing and retrieving users by an externalId
• Use OData Filter
