Clarification on Kerberos configuration for Gremlin Driver

I'm a little bit unclear on the role of the JAAS configuration file for the Gremlin client in the context of the gremlin-driver (rather than just the GremlinConsole).
Looking at https://tinkerpop.apache.org/docs/current/reference/#krb5authenticator
Is the naming convention around the jaasEntry name at all of relevance or can any gremlin-driver assume the existence of a GremlinConsole jaas entry? I'm assuming the mapping here between jaasEntry name and gremlin-driver configuration is done by setting the jaasEntry value on the ClusterBuilder but just looking for confirmation on that!
