[Dovecot] dovecot don't start

[Luca Stancapiano]

hi...I've a problem with dovecot 0.99.13-3 for fedora core 3. When I start
dovecot with "service dovecot start" it seems to start succesful but it is
a false message. It don't start and in /var/log/maillog I've this errors:


Apr  1 15:37:00 edim dovecot: Dovecot starting up
Apr  1 15:37:03 edim dovecot: Auth process died too early - shutting down
Apr  1 15:37:03 edim dovecot: child 9593 (auth) returned error 127
Apr  1 15:37:03 edim pop3-login: fd_send(-1) failed: Broken pipe

my configuration is :

protocols = imap imaps pop3 pop3s
imap_listen = [::]
pop3_listen = [::]
imaps_listen = [::]
pop3s_listen = [::]
ssl_cert_file = /usr/share/ssl/certs/dovecot.pem
ssl_key_file = /usr/share/ssl/private/dovecot.pem
login_dir = /var/run/dovecot-login
login = imap
login = pop3
mbox_locks = fcntl
auth = default
auth_mechanisms = plain
auth_userdb = passwd
auth_user = root


what does it?
