Re: Setting saslauthd home [solved]

["Gabriele Bulfon via Info" <info@xxxxxxxxxxxxxxxxxx>]

I found the reason.

 

First sasl_saslauthd_path must point to the full mux file (in my case /server/var/run/saslauthd/mux) and not the path given as home argument to saslauthd (in my case -m /server/var/run/saslauthd) : this is quite confusing.

This solved the original "socket operation on non-socket" problem.

 

The last problem "SASL size read failed" is about a wrong ldap library.

I noticed with ldd that saslauthd was linked with two different ldap libraries "libldap" and "libldap-2.4".

This is a Solaris/illumos only problem: the kernel comes with an original Solaris ldap library (libldap), so the openldap libraries are distributed with a different name (libldap-2.4).

I had to patch the configure.ac file like this:

This to force link with libldap-2.4 only!

Rebuilt cyrus-sasl component and package, updated test system, restarted both saslauthd and cyrus-imap services and now it works like a charm!

It would be nice to have a configure parameter to override default "-lldap" with a custom one.

Thanks for your help!

Are you restarted  saslauthd  before  imapd?  "Socket operation on non-socket" usually means inaccessible  saslauthd.pid

 

Sorry, I am newbie in Cyrus and as a sysadmin in general. My FreeBSD directory /var/run/saslauthd/ contains also three links to saslauthd, saslauthd-rc and sasldb2.db besides of mux, mux.accept,  and  saslauthd.pid itself.
