Unable to connect to localhost with mysql utilities I installed mysql utilities on my ubuntu server today, so I could use mysqldbcompare, but I just cannot connect to the mysql server with it (localhost). I created an entry into the .mylogin.cnf, using mysql_config_editor, as mentionned into the mysql utilities 1.6 documentation, and printed / tested it (with mysql), and it's ok. But if I try to run any mysql utilities command, it always fail with

ERROR: Access denied for user '****'@'localhost' (using password: YES)


(I put the stars myself instead of my user name).

I spent more than 2 hours searching the web, I have absolutely no clue of what's wrong... any idea ?

EDIT :
alright, let's do this step by step
First, my versions. Everything is on the same virtual machine : mysql server and client, and mysql utils.
My versions are :
MySQL server : Ver 14 Distrib 5.7.22
MySQL client : Ver 14 Distrib 5.7.22
MySQL utils : 1.6.1


First, using phpMyAdmin (which connects correctly to mysql), I create a user named userTest, with host % and password "bonjour!".
Then, I go to my host terminal, and type the following :
mysql_config_editor set --login-path=test --host=localhost --user=userTest --port=3306 --password
When asked, I enter the password "bonjour!"
Then, I try to connect to mysql using the login path (no user is named "test" on the database :
mysql --login-path=test
This connects me to mysql correctly :

Welcome to the MySQL monitor.  Commands end with ; or \g.

Your MySQL connection id is 17

Now I exit mysql and type a simple mysql utils command :
mysqlserverinfo --server=test
And I get 
ERROR: Access denied for user 'userTest'@'localhost' using password: YES
OK, so my suspicions were correct.
The python scripts of mysql utilies use the default "my_print_defaults" utility to get the credentials from a login path.
But the my_print_defaults call returns the password as a bunch of stars, unless you call it with -s...
So I modified the python script mysql/utilities/common/my_print_defaults.py to call the my_print_defaults executable with -s to get the password too. And now it works.
