Noel, thanks

MySQL on old, MariaDB on new

OK, KEYING in password as I have:

(you meant -u, no?)

]# mysql -p -u vmail
Enter password:

I've used the password i've made, NOT the string I have in
/etc/dovecot/mysql file

BUT, when I use OLDSERVER hashed string

on OLD server, it's OK

on NEW server, fail:


# mysql -p -u vmail
Enter password:
ERROR 1045 (28000): Access denied for user 'vmail'@'localhost'
(using
password: YES)


so, the hashed string I've copied /transfered from OLD server 'as
is'
doesn't work on NEW

how do I generate hashed string from my password ?
