Post subject:  Dovecot not generating 'private/auth' file - please help!
I've been fighting with Dovecot and Postfix for nearly 3 days now - I need some help!...

It seems Dovecot is not generating the private/auth file required for connections.

Mail.log
Code:
Sep  6 21:55:55 suncoastshores postfix/smtpd[11278]: warning: SASL: Connect to private/auth failed: No such file or directory
Sep  6 21:55:55 suncoastshores postfix/smtpd[11278]: fatal: no SASL authentication mechanisms


ls -l /var/spool/postfix/private/

Hostname
Code:
hostname
suncoastshores
hostname -f
suncoastshores.suncoastshores.com


Dovecot Main.cf (snippets)
Code:
# SASL parameters
# ---------------------------------
 
# Use Dovecot to authenticate.
smtpd_sasl_type = dovecot
# Referring to /var/spool/postfix/private/auth
smtpd_sasl_path = private/auth
smtpd_sasl_auth_enable = yes
broken_sasl_auth_clients = yes
smtpd_sasl_security_options = noanonymous
smtpd_sasl_local_domain =
smtpd_sasl_authenticated_header = yes


# General host and delivery info
# ----------------------------------
 
myhostname = suncoastshores.suncoastshores.com
myorigin = /etc/hostname
mydestination = suncoastshores.suncoastshores.com, localhost


10-master.conf (snippet)
Code:
  # Postfix smtp-auth
   unix_listener /var/spool/postfix/private/auth {
   mode = 0660
   user = postfix
   group = postfix
  }


What am I missing? Why won't Dovecot generate the private/auth file?

Generally, dovecot will log errors about why it can't or didn't create that file in either mail.log or wherever it is set to log to. You might want to investigate that.

Unfortunately the log file wasn't giving any more information that what I posted however, I changed auth_socket_path in 10-mail.conf to auth_socket_path = /var/run/dovecot/auth-master and now the private/auth file has been created.

Now I'm getting a Connection Refused message..
Code:
Sep  7 10:42:03 suncoastshores postfix/smtpd[19153]: warning: SASL: Connect to private/auth failed: Connection refused
Sep  7 10:42:03 suncoastshores postfix/smtpd[19153]: fatal: no SASL authentication mechanisms


My head's going to explode...

Solved by adding the following to the service auth section of /etc/dovecot/conf.d/10-master.conf
Code:
  unix_listener auth-master {
    mode = 0660
    user = vmail
    group = vmail
  }
