Re: [opensuse] Authentication Question Cyrus-Imap / Postfix

Dear list,

after reading several posts and websites, I finally got stuck with my
configuration on a openSUSE 11.4 box and help in any form is highly
appreciated.

I want to make sure that both SMTP (on submission port: 587) and IMAPs
(on port: 993) services are working with encryption, so that no clear
text passwords are send over the wire.

If I configure my Thunderbird mail client to work with Postfix on port
587, STARTTLS and non encrypted passwords, everything seems to work
fine. My problem results from Cyrus and everything seems to work if I
send out the passwords in plain and over the wire (no encryption at
all). Unfortunately, as far as I get it, I am not able to establish a
secure connection via STARTTLS or SSL/TLS. The thunderbird client always
loses its connection.

Here are some details about my configuration:

$> cat /etc/imapd.conf
<<<< SNIP
allowplaintext: yes
sasl_pwcheck_method: auxprop
sasl_mech_list: PLAIN LOGIN
sasl_auxprop_plugin: sasldb
tls_ca_file: /etc/postfix/certs/cacert.pem
tls_cert_file: /etc/postfix/certs/mail_signed_cert.pem
tls_key_file: /etc/postfix/certs/mailkey.pem
<<<<

$>cat /etc/sasl2/smtpd.conf
pwcheck_method: auxprop
auxprop_plugin: sasldb
mech_list: plain login

$> cat /etc/cyrus.conf
START {
recover cmd="ctl_cyrusdb -r"
idled cmd="idled"
}
SERVICES {
imap cmd="imapd" listen="imap" prefork=0
imaps cmd="imapd -s" listen="imaps" prefork=0
sieve cmd="timsieved" listen="sieve" prefork=0
lmtpunix cmd="lmtpd" listen="/var/lib/imap/socket/lmtp" prefork=0
}
EVENTS {
checkpoint cmd="ctl_cyrusdb -c" period=30
delprune cmd="cyr_expire -E 3" at=0400
tlsprune cmd="tls_prune" at=0400
}

Whenever I try to connect via thunderbird, the following messages appear:

$> tail /var/log/messages
Apr 12 15:22:42 hostXYZ imaps[32135]: executed
Apr 12 15:22:42 hostXYZ imaps[32135]: IOERROR: opening

Apr 12 15:22:42 hostXYZ master[32114]: service imaps pid 32135 in BUSY

Hope that somebody is able to help.

Thank you in advance.

I had this problem. Make sure you add the user cyrus to have read access to your certificate, and maybe read access to your private key too. That fixed it for me. I use STARTTLS on port 143.
