it might be because of socket authentication plugin:

In other words if you use "root" unix account you don't need password.

then he would have seen the "mysql" database in "show databases"

    Thank you.

    I noticed some anonymous user entries in mysql.user. I have executed
    the mysql_secure_installation and removed those users as well.

        Check table mysql.user: you probably have the account

        When running SHOW DATABASES you see only the databases which you
        have some permissions.

        *Oggetto:* [Maria-discuss] Is this normal behaviour?

        All,

        When I tried to connect in centos 7 mariadb 10.2.11 server using
        root user, by mistake I gave wrong user name, but it connected
        successfully. I am not sure why. When I check show databases, it
        didnt list all DBs, but when I connect with root again, I can
        see all valid Dbs.

        Is this normal that even if I give wrong user, it authenticate
        into DB server from root.

        [root@ipaddr ~]# mysql -u rot
