mysql cli\shell

Able to access DBs thru various DB clients, but unable to access using the mysql cli or shell.

Running MaxScale 2.2 connecting to an Aurora Mysql 5.6 backend.

When trying to connect with various accounts from the cli receive:

ERROR 1045 (28000): Access denied for user 'username'@'::ffff:10.X.X.X' (using password: NO)

Username and IP info redacted. Curious is even though password is be supplied deny is saying using password: NO

Command being issued is:

mysql -h maxscale.ourdomain.com -u username -p

Note: user is not root

Pointing the host directly to the aurora host allows access.
