You won't be able to pull people's passwords out of the database, even if you're accessing it directly. Passwords are stored in most systems as a hash, which is used to check against the password. This is for security, in case someone were to acquire access to your database.

If you want to access the MySQL database, you can use 'logmysql' as the zimbra user.

Is this what you are looking for?

su - zimbra
zmlocalconfig -s | grep mysql | grep password
