    Question PostFix and DoveCot: No SASL Authentication Mechanisms

    After following the guide provided by debuntu.org (http://www.debuntu.org/how-to-virtua...x-and-dovecot/) which was very helpful, I immediately began having issues with SASL autentication. What provoked me to look in the mail.log to see the following message was an error message on thunderbird that stated "Thunderbird failed to find the settings for your email account." The error that repeats in mail.log is as follows:
    Code:
    Jan  6 14:16:45 Jesse-Server postfix/smtpd[22109]: connect from unknown[192.168.2.1]
    Jan  6 14:16:45 Jesse-Server postfix/smtpd[22109]: warning: SASL: Connect to private/auth failed: No such file or directory
    Jan  6 14:16:45 Jesse-Server postfix/smtpd[22109]: fatal: no SASL authentication mechanisms

    Jan  6 14:18:26 Jesse-Server postfix/anvil[22112]: statistics: max cache size 1 at Jan  6 14:16:45
    This provoked me to look for private/auth, but as you can see below, no such file exists...
    Code:
    root@Jesse-Server:/home/clucky# ls -l /var/spool/postfix/private/auth
    ls: cannot access /var/spool/postfix/private/auth: No such file or directory
    What I would like to know is where is my private/auth folder? Am I using the wrong version of dovecot perhaps? In an unrelated note, when I type service dovecot restart it says the following:
    Code:
    stop: Unknown instance: 
    dovecot start/running, process 9394
    Here is the configuration for postfix labled main.cf:
    Code:
    smtpd_banner = $myhostname ESMTP $mail_name (Debian/GNU)
    biff = no
    # appending .domain is the MUA's job.
    append_dot_mydomain = no
    # Uncomment the next line to generate "delayed mail" warnings
    #delay_warning_time = 4h
    # TLS parameters
    smtpd_tls_cert_file=/etc/ssl/certs/ssl-cert-snakeoil.pem
    smtpd_tls_key_file=/etc/ssl/private/ssl-cert-snakeoil.key
    smtpd_use_tls=yes
    smtpd_tls_session_cache_database = btree:${queue_directory}/smtpd_scache
    smtp_tls_session_cache_database = btree:${queue_directory}/smtp_scache
    #vhost with mysql params
    #virtual_alias_domains needs to be unset
    virtual_alias_domains =
    virtual_mailbox_domains = mysql:/etc/postfix/virtual/mysql-virtual-mailbox-domains.cf
    virtual_mailbox_maps = mysql:/etc/postfix/virtual/mysql-virtual-mailbox-maps.cf
    virtual_alias_maps = mysql:/etc/postfix/virtual/mysql-virtual-alias-maps.cf, mysql:/etc/postfix/virtual/mysql-virtual-email2email.cf
    virtual_uid_maps = static:5000
    virtual_gid_maps = static:5000
    virtual_transport = dovecot
    dovecot_destination_recipient_limit = 1
    myhostname = worldofclucky.net
    alias_maps = hash:/etc/aliases
    alias_database = hash:/etc/aliases
    myorigin = /etc/mailname
    mydestination = worldofclucky.net, localhost
    relayhost =
    mynetworks = 127.0.0.0/8
    mailbox_command = procmail -a "$EXTENSION"
    mailbox_size_limit = 0
    recipient_delimiter = +
    inet_interfaces = all
    smtpd_sasl_type = dovecot
    smtpd_sasl_path = private/auth
    smtpd_sasl_auth_enable = yes
    smtpd_recipient_restrictions = permit_mynetworks,permit_sasl_authenticated,reject_unauth_destination
    and here is dovecot.conf:
    Code:
    protocols = imaps
    mail_location = maildir:/var/vmail/%d/%n/Maildir
    ## uncomment this if you already have email from
    ## courier for instance.
    #namespace private {
    #  separator = .
    #  prefix = INBOX.
    #  inbox = yes
    #}
    ## change section "protocol lda" to:
    protocol lda {
      # Address to use when sending rejection mails.
      postmaster_address = postmaster@worldofclucky.net
      log_path = /var/vmail/dovecot-deliver.log
      # Hostname to use in various parts of sent mails, eg. in Message-Id.
      # Default is the system's real hostname.
      #hostname =
      # Support for dynamically loadable plugins. mail_plugins is a space separated
      # list of plugins to load.
      #mail_plugins =
      #mail_plugin_dir = /usr/lib/dovecot/modules/lda
      # Binary to use for sending mails.
      #sendmail_path = /usr/lib/sendmail
      # UNIX socket path to master authentication server to find users.
      auth_socket_path = /var/run/dovecot/auth-master
      # Enabling Sieve plugin for server-side mail filtering
      # handy for storing spam in their folders
      mail_plugins = cmusieve
      global_script_path = /var/vmail/globalsieverc
    }
    ## in section auth default
    ## change :
    mechanisms = plain login
    ## comment out "passdb pam"
    ## and make sure the following is in
    ## to look for users in the DB
      passdb sql {
        # Path for SQL configuration file, see /etc/dovecot/dovecot-sql.conf for example
        args = /etc/dovecot/dovecot-sql.conf
      }
    ## and add this so dovecot does not deal with uid/gid
    ## we use uid and gid 5000 for everybody
      userdb static {
        args = uid=5000 gid=5000 home=/home/vmail/%d/%n allow_all_users=yes
      }
    ## next make sure the section "socket listen" looks like this
    ## so dovecot and postfix work happily together
      socket listen {
         master {
           path = /var/run/dovecot/auth-master
           mode = 0600
           user = vmail # User running Dovecot LDA
           #group = mail # Or alternatively mode 0660 + LDA user in this group
         }
         client {
          # The client socket is generally safe to export to everyone. Typical use
          # is to export it to your SMTP server so it can do SMTP AUTH lookups
          # using it.
          path = /var/spool/postfix/private/auth
          #path = /var/run/dovecot/auth-client
          mode = 0660
          user = postfix
          group = postfix
         }
       }
    Any help would be greatly appreciated, and if you need any more errors/configs, do not hesitate to ask. Thank you in advanced!
