Check table mysql.user: you probably have the account '%'@localhost. It's a pattern, and rot@localhost matches.When running SHOW DATABASES you see only the databases which you have some permissions. Federico Da: Karthick Subramanian <ksubramanian@paycommerce.com> A: Maria Discuss <maria-discuss@lists.launchpad.net> Inviato: Giovedì 4 Gennaio 2018 6:01 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 rotWelcome to the MariaDB monitor.
