DualShield utilizes this attribute to retrieve the user ID from the traffic forwarded by Entra ID. Typically, Entra ID transmits data in form format, with id_token_hint being one of the form fields. The id_token_hint is a JWT token containing the oid claim, which represents the user account. This oid value can be mapped to the id column in DualShield's user table.
From DualShield's perspective, this attribute serves as an input parameter, which is why the Get Input option must be enabled.
