All sysdba connections which omit the Net service names.

Attempting to connect locally or via bequeath using the following:

sqlplus "/ as sysdba"

This yields an error:

ORA-12514:TNS:listener does not currently know of service requested in connect descriptor

handling this connection and yet it's throwing a listener error.
