SCIM - Custom user schema extension

OneWelcome provides their customers with the possibility to extend the User-schema with additional attributes.

This will give customers the possibility to store attributes that are needed otherwise in the OneWelcome environment.

Custom attributes

Specification of custom attributes needs to include:

• Attribute name. Attribute names cannot contain colons (":").
• Sub-attributes can only be singular; multi-valued sub-attributes are not supported.
• Custom attributes can be simple or complex (e.g. having sub-attributes).
• Custom attributes can be singular or multi-valued.
• Custom attributes and sub-attributes can have any of the attribute types, as defined in SCIM: Core Schema 1.1.

Characteristics

Creation of the extension has the following characteristics:

• OneWelcome can configure the extension in the environment on behalf of the tenant-admin.
• The extension needs to be created before going into production; it needs to happen on an empty database. Changes in schema when identities have already been created may cause identity-data to exist in the database that doesn't comply to the updated custom schema.
• The extension will be named after the customer (e.g. MyCompanyUserExtension).

Behavior

When the extension is configured, the following behavior is applied:

• The extension is applied to all identities of all segments.
• Resulting User-operations (Post, Put, Patch, Get) will support the created extension in a way that is compliant with the Schema Extension model as specified in SCIM: Schema v1.1.
• OneWelcome will apply validation on the (sub)attribute type.
• Custom attributes can be configured as being identifiers for the identity. A typical example would be 'customerNumber', 'subscriptionNumber' or 'licensePlate'.
• OneWelcome's attribute meta data extension is applicable to custom attributes.
