Implementing multiple users within Identity and Access Bounded Context in Domain Driven Design

I am developing a multi-tenant JobBoard Application using DDD approach. I have read to a great extent both the blue and red books. I have also read many articles on DDD online. However, I have not seen any easy-to-comprehend example on the implementation of the Identity and Access bounded context in this regard.

My application structure looks like this:

A tenant creates a JobBoard. A job board (which belongs to a tenant) has two users: Employer and Job Seeker.

I have two bounded context namely: Identity and JobBoard.

My question is what would be the best way to implement the Employer and JobSeeker User?

  1. Should I have both the Employer and JobSeeker as entities (Aggregates) within the Identity bounded context or

  2. Should I have a User Entity (Aggregate) within the Identity Bounded context and have both Employer and JobSeeker as Role types of a Role Value Object which will be an attribute of the User Class.

Thanks.

Unless Employer and JobSeeker don't authenticate in the same way, or you have security restrictions that require the two to be separated, I would have a single User object.

As an aside, it is not necessarily worthwhile to implement your own Identity subdomain, or at least to do so with a full fledged DDD model - aggregates, entities, etc.

I would choose no. 2

Employer and JobSeeker seem to have a meaning only in the JobBoard Bounded Context so you should implement them as value objects in that BC, created based on the Role from Identity Bounded Context.
