The recommended permissions for the vcl user on the backend are correct
(SELECT, INSERT, UPDATE, DELETE). Also it's probably not good to have
anything remotely accessing your database with All Privileges - just from a
security perspective. At some-point in the future we would like to moved to
stored procedures - which would allow stricter permissions.
Are the database and vcld running on the same machine? maybe the
'username'@'localhost' is creating a problem.

I've added my management node to the DB, but I couldn't get the vcld

I believe this is default user permissions bug because when I give my vcl
user in the database full permissions (All Privileges) instead of the
recommended in the instructions (SELECT, INSERT, UPDATE, DELETE), it
works. What are the right permissions for a frontend user? What are the
right permissions for a backend user? Do the instructions need to be
updated?
Best,
Brian
