Re: imapd is not talking to saslauthd

[Ken Murchison <murch@xxxxxxxxxxxx>]

Hmm.

I just switched my dev box to using saslauthd and it just worked.  I'm sure your problem is something simple, but its escaping me at the moment. 

When imtest fails, what is logged in the Cyrus IMAP log (wherever local6 is logged)

Hi Michael,

What are the permissions on the socket that saslauthd is listening on?

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@cyrus3:/ # testsaslauthd -u mike -p mike

0: OK "Success.“

and if i run

root@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

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
