I'm trying to configure dovecot on a SUSE system, and having trouble with the simplest possible authentication scheme: using the standard Linux users and passwords.

My configuration is:

dovecot -n
# 1.1.7: /etc/dovecot/dovecot.conf
# OS: Linux i686 openSUSE 11.1 (i586) 
protocols: imap pop3
ssl_listen: *
ssl_disable: yes
disable_plaintext_auth: no
login_dir: /var/run/dovecot/login
login_executable(default): /usr/lib/dovecot/imap-login
login_executable(imap): /usr/lib/dovecot/imap-login
login_executable(pop3): /usr/lib/dovecot/pop3-login
mail_executable(default): /usr/lib/dovecot/imap
mail_executable(imap): /usr/lib/dovecot/imap
mail_executable(pop3): /usr/lib/dovecot/pop3
mail_plugin_dir(default): /usr/lib/dovecot/modules/imap
mail_plugin_dir(imap): /usr/lib/dovecot/modules/imap
mail_plugin_dir(pop3): /usr/lib/dovecot/modules/pop3
auth default:
  default_realm: renomustangcarclub.com
    driver: pam
    driver: passwd

Attempts to log in:

99-26-248-100:~ dramsey$ telnet renomustangcarclub.com pop3
Connected to renomustangcarclub.com.
Escape character is '^]'.
+OK Dovecot ready.
user dramsey
pass raskin
-ERR Authentication failed.

Looking in the mail log file:

Mar  5 16:40:55 Microstar dovecot: pop3-login: Disconnected (auth failed, 1 attempts): user=<dramsey at renomustangcarclub.com>, method=PLAIN, rip=, lip=

Any ideas?
