[Dovecot] Plain password not authenticating

I'm trying to set up a temporary mailserver using Debian Sarge and Dovecot 1.0 with maildir format. My only previous experience has been on a simple imap server.

I have read the wiki documentation and searched the archives, but can't tie down my problem. The log tells me

Info: passwd-file(anne) : unknown user.

I have set auth_userdb = passwd-file /etc/imap.passwd auth_passdb = passwd-file /etc/imap.passwd

and created the /etc/imap.passwd file as anne:{plain}mypassword:1000:1000::/home/anne

What have I missed?
