Connection to Amazon RDS MySQL instance fails with `init_connect command failed` I'm attempting to open a connection from my Amazon RDS instance to my local dev machine. I added my IP to the security policy in Amazon's panel (read: whitelisted myself in the firewall) and added my user in MySQL:

grant usage on bar.* to foo@0.0.0.0 identified by "foobar";
grant all privileges on bar.* to foo@0.0.0.0;


Assume that 0.0.0.0 is actually my IP.

I then attempt to connect via the command-line MySQL client:

[wk@batman ~]$ mysql  --host=1.1.1.1 --user=foo -p
Enter password:

I'm not sure what could be causing this error - the results I could find on Google pertained to database replication. Does anyone have any idea what's wrong?
This is because the user does not have execute grant global, to fix it

GRANT EXECUTE ON *.* TO user_name;
