Thanks for your reply.

Now I can see more info after turning on all those debugs

Here it is

Here is my dovecot.conf (Note: I have removed all the comments)

## Dovecot configuration file

protocols = imap imaps pop3 pop3s
listen = *

disable_plaintext_auth = no

log_path = /var/log/dovecot-deliver.log 
info_log_path = /var/log/dovecot-deliver.log 

log_timestamp = "%Y-%m-%d %H:%M:%S "

login_user = postfix

login_greeting = Dovecot IMAP server!

mail_location = maildir:~/Maildir

mail_privileged_group = mail

mail_debug = yes
verbose_proctitle = yes

protocol imap {
  login_executable = /usr/lib/dovecot/imap-login
  mail_executable = /usr/lib/dovecot/imap
  imap_client_workarounds = outlook-idle delay-newmail netscape-eoh tb-extra-mailbox-sep
}

protocol pop3 {
  pop3_uidl_format = %08Xu%08Xv
}

protocol managesieve {
}

protocol lda {
  postmaster_address = 
  hostname = ubuntuserver 
  sendmail_path = /usr/lib/sendmail

  rejection_subject = Rejected: %s
  rejection_reason = Your message to <%t> was automatically rejected:%n%r

  auth_socket_path = /var/run/dovecot/auth-master
}

auth_username_format = %Lu
auth_verbose = yes
auth_debug = yes
auth_debug_passwords = yes

auth default {
  mechanisms = plain

  passdb pam {
  }

  userdb passwd {
  }

  user = root

  socket listen {
    master {
      path = /var/run/dovecot/auth-master
      mode = 0660
      user = mail 
      group = mail
    }
    client {
      path = /var/spool/postfix/private/auth-client
      mode = 0660
      user = postfix
      group = postfix
    }
  }
  !include_try /etc/dovecot/auth.d/*.auth
}

dict {
}

plugin {
}

# Config files can also be included. deliver doesn't support them currently.
#!include /etc/dovecot/conf.d/*.conf
# Optional configurations, don't give an error if it's not found:
!include_try /etc/dovecot/conf.d/*.conf
#!include_try /etc/dovecot/extra.conf

I think the issue is with PAM authentication. How do I configure the PAM authentication?

Any help would be much appreciated.

Thank you

You might try turning on the various DEBUG modes in Dovecot.
In your dovecot.conf file :
Something like this :
-------------------------------------
auth_debug = yes
auth_debug_passwords = yes
auth_verbose - yes
verbose_proctitle = yes
mail_debug = yes
log_path = /var/log/dovecot.log
info_log_path = /var/log/dovecot-deliver.log
-------------------------------------
After edit, restart dovecot.
Then tail your log (tail -f /var/log/dovecot-deliver.log) while
attempting to check mail.

You should see a bit more info that might help.
(be sure to turn it all back off. it will sometimes log the passwords
and when using plaintext, thats bad.)

Hope this helps,

I have checked the status for postfix and dovecot, and they both are up and running by using telnet. I have even installed openldapadmin to check and see if I've got the ldap working. I could login to openldapadmin and saw myself there with uid=msmith.
