[Dovecot] I can't logon to the mail server using an NIS user account

[Kayode Odeyemi]

Below is my configuration

# 2.0.13: /etc/dovecot/dovecot.conf
# OS: Linux 3.0.0-17-server x86_64 Ubuntu 11.10
auth_mechanisms = plain login
mail_location = maildir:/nfs/users/%u/Maildir
passdb {
  args = scheme=CRYPT username_format=%u /etc/dovecot/users
  driver = passwd-file
}
protocols = " imap pop3"
service auth {
  unix_listener /var/spool/postfix/private/auth {
    group = postfix
    mode = 0660
    user = postfix
  }
}
service imap-login {
  inet_listener imap {
    port = 143
  }
  inet_listener imaps {
    port = 993
    ssl = yes
  }
}
ssl_cert = </etc/ssl/certs/mail.prisaltd.local.crt
ssl_key = </etc/ssl/private/prisa.key
userdb {
  args = username_format=%u /etc/dovecot/users
  driver = passwd-file
}
protocol imap {
  imap_client_workarounds = tb-extra-mailbox-sep
  imap_logout_format = bytes=%i/%o
  mail_plugins =
}

/etc/pam.d/common-password
--------------------------------------------

# here are the per-package modules (the "Primary" block)
password [success=1 default=ignore] pam_unix.so obscure sha512 nis
# here's the fallback if no module succeeds
password requisite pam_deny.so
# prime the stack with a positive return value if there isn't one already;
# this avoids us returning an error just because nothing sets a success code
# since the modules above will each just jump around
password required pam_permit.so
# and here are more per-package modules (the "Additional" block)
password optional pam_ecryptfs.so
# end of pam-auth-update config

Please what am I doing wrong? I've been on this for 2 weeks.
