Hello,

Our Postfix setup uses multi-instance feature. I would like to enable dovecot SASL mechanisms in postfix. Open two unix sockets is not a problem for us:

service auth { unix_listener /var/spool/postfix-instance1/private/auth { mode = 0660 user = postfix group = postfix } unix_listener /var/spool/postfix-instance2/private/auth { mode = 0660 user = postfix group = postfix } }

Lets assume, that postfix-instance1 uses LDAP1, and postfix-instance2 uses LDAP2. How can I use different userdb and passdb databases for those sockets?

Hi again,

After long googling we have found this link: http://dovecot.2317879.n4.nabble.com/multiple-passdbs-and-auth-sockets-td437...

Ajusted my configs, and now I'm facing this problem:

2014-09-09T08:57:19.954477+03:00 mail-gw1 dovecot: ktu: Error: doveconf: Fatal: execvp(/run/dovecot/dovecot/auth) failed: No such file or directory

That is strange, because our dovecot is 2.2.9 from debian wheezy-backports and auth executable is in /usr/lib/dovecot/auth. Source lines responsible for this error is in doveconf.c:

$ grep -n execvp src/config/doveconf.c 850: execvp(exec_args[0], exec_args); 851: i_fatal("execvp(%s) failed: %m", exec_args[0]); $

Somehow exec_args[0] comes not as /usr/lib/dovecot/auth, but /run/dovecot/dovecot/auth. Not sure how is that possible.

As author states, Dovecot v1.x is better working with multiple auth {} sections. I'm working with postfix multiple instances and SASL. I would be glad to see such capability in dovecot v2.x. Maybe my case is 1 out of the million?
