Hello dear list. I had a look to the mysql.user table and found four users at localhost ; two of them seem odd to me : 1 mariadb.sys with no password 2 mysql with the password 'invalid'. I guess I can delete user 'mysql'@'localhost' but what about 'mariadb.sys'@'localhost' ? In the slackware box, those users don't exist. Thanks for advise. Regards. -- Philippe
