Thanks a lot, Wash.
So, now I can login as real users as well as virtual users.
However, there is still a problem with the mailboxes. 

If I use the following in dovecot.conf: 

  default_mail_env = maildir:%h/Maildir
  default_mail_env = maildir:/usr/local/virtual/%u/

I can not access mails in real users' mailbox, only 
virtual users can. If I commented the second line: 

  default_mail_env = maildir:%h/Maildir
#  default_mail_env = maildir:/usr/local/virtual/%u/

I can access mails in real users mailbox (for example, 
via Squirrelmail), but I cannot access virtual users' mail.

Can anyone help me?

Thanks.
