how do I generate hashed string from my password ?
use this sql command:
GRANT SELECT ON vmail TO 'vmail'@'127.0.0.1' IDENTIFIED BY
PASSWORD('yourpassword');
or if you just want to see the hash:
SELECT PASSWORD('yourpassword');
Sami, thanks
I'm running in circles here.. I thought it worked once, but, couldn't
repeat it after
OK, I've made user 'test' with pw 'test1234'
using keyborad to enter test1234 I get:
# mysql  -u test -p
Enter password:

HUH?
Are you trying to login to mysql using the hash itself?
That wont work, and its not what you are supposed to be doing as evident
by fact you can login using plain password, you're looking in the wrong
area, since the database stores passwords hashed, you enter it in, in
plain text, the database them does its magic to convert what you entered
in, into a hash and does the matching in its own backend, so to speak.
if you put in your dovecot sql file, the vmail password in plain text
and not hashed output, it should work, you have to make sure the sql
file is chmod 600 so any normal users with access cant read the file(s).
