Signer Maintenance is the usage scenario in which a privileged user or signer updates the attributes of a signer (e.g. his own).
The starting point of this scenario is that a privileged user or signer initiates a request for user authentication at the SSSrv/UI where the user authentication is performed using via the IdP. Optional when the user is a privileged user the signer is selected whose attributes should be updated. The request for updating attributes of a signer then is send by the privileged user or signer to the SSSrv/UI and then goes its way along to the SAM. When the request is retrieved, the SAM verifies that the requestor is authenticated and identified. If the authenticity and identity check is successful, the SAM maintains a Signer's user record based on the data it received with the request. The SAM updates a Signer's authentication data in the form of assigned certificates in the SAM DB.
