imapd is not talking to saslauthd

[Michael Rüger]

Hi

(btw. i was Guest39278 on IRC yesterday and got the chance to introduce myself on googletalk)

I’m trying to set up imapd to use saslauthd for authentication.

I have already a running saslauthd which uses PAM. I can run this

root at cyrus3:/ # testsaslauthd -u mike -p mike
0: OK "Success.“

and if i run

root at cyrus3:/ # testsaslauthd -u mike -p abc
0: NO "authentication failed“

i get that logged in auth.log like this

Jan 30 21:43:53 cyrus3 saslauthd[88721]: do_auth         : auth failure: [user=mike] [service=imap] [realm=] [mech=pam] [reason=PAM auth error]

In imapd.conf i have

sasl_pwcheck_method: saslauthd

Now i’m authenticate against imapd

root at cyrus3:~ # imtest -t "" -u mike -a mike -w mike localhost
S: * OK [CAPABILITY IMAP4rev1 LITERAL+ ID ENABLE STARTTLS LOGINDISABLED AUTH=SCRAM-SHA-1 AUTH=DIGEST-MD5 AUTH=CRAM-MD5 AUTH=NTLM SASL-IR] cyrus3.intern.rueger.me Cyrus IMAP 3.0.5 server ready

Nothing is reported in auth.conf

If i do this

root at cyrus3:~ # saslpasswd2 -c mike at cyrus3.intern.rueger.me
…<entering „mike“ twice here>
root at cyrus3:~ # imtest -t "" -u mike -a mike -w mike localhost

C: S01 STARTTLS
…
Authenticated.
Security strength factor: 256

it is working against local db BUT NOT against saslauthd.

How do i setup imapd to talk to saslauthd?

BTW i’m using
* cyrus-imapd30-3.0.5
* cyrus-sasl-2.1.26_13
* cyrus-sasl-saslauthd-2.1.26_3
on FreeBSD 11.1

Thank you for any help,
Mike
