[Dovecot] problem authenticating passwd

[richard at richard-brouwer.nl]

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
