I am running FreeBSD with posftix and dovecot. There virtual domains and users and postfix authenticates users using sasl and dovecot.
Today I've performed a server upgrade and sasl authentication works no more. It worked for the last 4 months without problems.
In postfix logs I get
May 14 13:34:21 sfdsa postfix/smtpd: warning: SASL: Connect to smtpd failed: No such file or directory
May 14 13:34:21 sfdsa postfix/smtpd: fatal: no SASL authentication mechanisms
postfix is running, dovecot is running, saslauthd is running.
For me everything seems ok, what file or directory has been changed and can not be found anymore?
Please help me if you can, this is a production server.
