dovecot - Apr 2006 - problem authenticating passwd

Maybe you guys seen this question a thousand times but really I can't find a
solution. So is there anybody who can give me a direction or a clue to solve my
problem.
I configured my dovecot as follows:

protocols = imap pop3 imaps pop3s

login_chroot = yes

login_user = dovecot

auth_verbose = yes


auth default {
  mechanisms = plain


  passdb passwd { args = /etc/passwd
  }

  userdb passwd { args = /etc/passwd
  }

  user = root
}





The maillog gives me that there is password mismatch, but I'm 100 % sure
that the password is correct. I allso looked in my /etc/passwd file and the user
is there. The user is all so able to login the Linux system. My system is Fedora
redhat RC 5. Dovecot is v1.0.beta2. I attached the last rules of my maillog. Is
there anybody who can please help me.

Thx in advance richard

This is the tail of the maillog:

Perhaps you should be using PAM or shadow for the passdb?

BTW with this information archived on Google, I hope you changed your 
password!

Did you try using just "richard" as the username, or adding 
"richard-brouwer.com" as an auth realm?
