I've been googling and reading the mailing lists all afternoon and I just can't figure this out. I've even tried trussing (Solaris) sync_server and saslauthd. When I run synctest against my 2.3.16 server it comes back with an auth error: badlogin: mail.cpicorp.com [192.168.25.10] PLAIN [SASL(-4): no mechanism available: Couldn't find mech PLAIN] Of course, if I use imtest to hit imapd on the same machine it logs in fine with the PLAIN mech. I found a similar post on google, but I couldn't find any resolution to the issue. One question would be whether sync_server actually honors the /etc/imapd.conf sasl settings. In my case, it's just: allowanonymouslogin: no allowplaintext: yes sasl_pwcheck_method: saslauthd Like I said, IMAP works fine, it's just sync_server that seems unhappy. Any guidance would be appreciated.
