MySQL / MariaDB and passwords

I'm on a debian9 an use MariaDB 10.1.38 on a remote host. Infront of the db-hosts is a MaxScale Proxy 2.2.20 In VM I set Password storage mode = Only store hashed passwords.

Now when I create a new "Virtual Server" VM put the passwort in the "authentication_string" field. But in MariaDB the "password" field is still present unlike in MySQL > 5.7 (I guess). Now the MaxSale uses the "password" field to authenticate users.

Is it possible to force VM to use the "password" field instead of "authentication_string" or even set it in both?

Howdy -- thanks for contacting us!

I'm unfortunately not sure about that, but I'm passing this along to Jamie for comment. He'll know whether that's possible, and how to go about that.

This could be happening because Virtualmin can't detect the real MySQL version properly.

If you connect to your MySQL server (via the proxy) as root and run select version() , what does is output?

root is deactivated but I've a equivalent this user virtualmin uses to connect lets say "virtualmin_sql" running with this user it shows:

MariaDB [(none)]> select version(); +--------------------------+ | version() | +--------------------------+ | 10.1.38-MariaDB-0+deb9u1 | +--------------------------+ 1 row in set (0.01 sec)

I think the issue here is that Virtualmin should be using the alter user command to set the password, rather than writing to authentication_string directly, because it assumes that this is only possible in MariaDB 10.2 and above.

Which Virtualmin version are you running there?

6.06-2 when the server go to production it will be a pro version.

Can you post the output from the SQL command desc mysql.user on your system?

this is from the user with witch vm connet to the mysql
