This is the name property of a storage auth key object, a stored authentication credential, such as a CHAP secret, that UCS uses to authenticate itself to an external storage target. An admin monitoring or configuring storage auth keys uses this name to tell one instance apart from another without having to parse the full DN. For example, an admin scanning a list of storage auth keys attached to a storage target would read this name field to pick out the specific one they intend to modify or check.
