Description
Account service offers operations to manage a CollectionSpace account. To securely access the CollectionSpace services, an account for a user is required in the system. An account is associated with an identity. The identity could either reside in [collectionspace:CollectionSpace Identity Provider (CSIP)] which is the default identity provider or a foreign identity provider such as CalNet or an OpenID provider. Account service also provides a user management interface for the CSIP.
In release 0.4 only CSIP is supported
Key Concepts
A CollectionSpace user's identity could reside in the default identity provider or a foreign identity provider. Account Service manages an identity only if the identity is stored in the realm managed by the default identity provider. That means, Account Service also provides identity management functions for the default identity provider.
Relationships
Following describes the relationship between an Account, a Person and a User in the [default identity provider].
- An account is associated with one person.
- An account could be associated with one or more tenants.
- An account is always associated with one user identity. This user identity could be managed by CSIP or by a 3rd party identity provider.
Assumptions
- Tenant provisioning has already taken place before provisioning any account for that tenant.
- At the time of provisioning a tenant, an administrator account is provisioned off-band (without using the account service).
- Account service is not a management interface for the 3rd party identity providers.
Account Provisioning
Every user of CollectionSpace should complete registration or signup process. This process is called account provisioning. During this process, in addition to typical user specific attributes such as screen name, userid, password (only for [default id provider]), email, etc., the system would explicitly ask the user to provide tenant specific information. This information could include unique tenant identifier, tenant name, etc. It would be possible to associate with multiple tenants (e.g. all of BNHM) with the same account. On successful completion of the request, the system would create an entry into its [Accounts] database for the user. The system would also associate that account with given tenant(s).
How to obtain tenant specific information?
The tenant specific information should be available to the user from the tenant organization. For example, the administrator of the Museum of Moving Images (MMI) could provide this information to the users of collection of MMI on CollectionSpace. It is assumed that the tenant is already provisioned in CollectionSpace.
Approval process
If users are registered by a tenant administrator, no approval would be necessary during account provisioning. If that is not the case and the user is self-registering, approval by the tenant would be needed for the account provisioning process to complete. On successful approval from the tenant administrator(s), user would be associated with the respective tenant(s). Note that it should be possible for a tenant administrator to associate an already registered user with the tenant.
Account Provisioning Scenarios
This section describes how accounts are provisioned in CollectionSpace. There are two scenarios.
- Account for a user managed by CollectionSpace's default identity provider
- Account for a user managed by a 3rd party identity provider such as CalNet, LDAP, OpenId provider, etc.
User managed by CollectionSpace identity provider (CSIP)
- The [account create (POST)] request from service consumer provides account information including user id and one or more tenant ids to which the user is associated with.
- The account service creates an account.
- Person service is called to create a person.
- Account service registers userid and password with CSIP.
- Account service registers associates given tenant(s) with the account.
User managed by a 3rd party identity provider
- The [account create (POST)] request from service consumer provides account information including user id and one or more tenant ids to which the user is associated with.
- The account service creates an account.
- Person service is called to create a person.
- Account service registers associates given tenant(s) with the account.
Issues
- The Person Service is the System of Record (SOR), or authoritative data source, for personIds.
- The SOR for systemIds is TBD.
