User attribute mapping as key is considered as custom attribute mapping and is added to the issued tokens. However, the following values are an exception to this behaviour.
- username
- realName
- name
- group
- userid
The following limitations apply when using custom attribute mapping:
- A maximum of 30 custom user attribute mappings can be added for a provider. If the count exceeds the maximum threshold, then there can be potential performance impact.
- Custom claim mapping for a provider can only be modified by making changes directly in the idpconfig.json file. Custom claims configured for a provider cannot be modified from Hyland IdP Administration client or through the provider's modification API endpoint.
- Only single-valued attributes are supported as part of custom user attribute mapping. For example, HireDate to add hire date information.
