auth.set_attribute
==================

Set current user's `attributes` dictionary `key` to `value`.

e.g. Setting key="foo" value="var" will result in {"attributes": {"foo": "bar"}}

Attributes set here will appear in the `auth.me` API response under the `attributes` field.

WARNING: this API endpoint exists solely for the use of the TrueNAS UX team. The data stored in these attributes *must* be considered opaque from the perspective of the middleware backend, with specific documented exceptions. This endpoint should not be used or relied on by any third-party scripts or workflows.

WARNING: this API endpoint is not intended for storing security-sensitive information. The backend storage for this data is not encrypted and it is indexed by unix user id rather than database ID, which exposes a risk of stale settings being reused if a new user gets assigned the same unix user id as an previously-existing one. This is of particular concern when users are provided by directory services.
