[[Qmail + LDAP Configuration ]]


Qmail Downloads

Check for gcc


wget http://www.qmailrocks.org/downloads/qmailrocks.tar.gz

wget http://www.nrg4u.com/qmail/qmail-ldap-1.03-20060201.patch.gz

wget http://packages.sw.be/rpmforge-release/rpmforge-release-0.3.6-1.el5.rf.i386.rpm


rpm -Uhv rpmforge-release-0.3.6-1.el5.rf.i386.rpm

yum install openldap* yum install zlib* yum install glib yum install gcc-c++ yum install gdbm*


1. yum install openssl-devel


2.Qmail Downloads

First create a new directory where you will store your qmail package.

mkdir /downloads

cd /downloads

Download the qmail package (or tarball).

wget http://www.qmailrocks.org/downloads/qmailrocks.tar.gz

Download qmail-ldap patch.

wget http://www.nrg4u.com/qmail/qmail-ldap-1.03-20060201.patch.gz

Unpack the downloaded qmail package.

tar -zxvf qmailrocks.tar.gz


3.Creating initial qmail directories.

mkdir -p /var/qmail

mkdir /usr/src/qmail


4.Creating all needed users and groups:


groupadd nofiles

useradd -g nofiles -d /var/qmail/alias -s /sbin/nologin -p'*' alias

useradd -g nofiles -d /var/qmail -s /sbin/nologin -p'*' qmaild

useradd -g nofiles -d /var/qmail -s /sbin/nologin -p'*' qmaill

useradd -g nofiles -d /var/qmail -s /sbin/nologin -p'*' qmailp


groupadd qmail

useradd -g qmail -d /var/qmail -s /sbin/nologin -p'*' qmailq

useradd -g qmail -d /var/qmail -s /sbin/nologin -p'*' qmailr

useradd -g qmail -d /var/qmail -s /sbin/nologin -p'*' qmails


groupadd vmail

useradd -g vmail -s /bin/true vmail


5.Unpacking qmail, ucspi-tcp and daemontools


cd /usr/src/qmail

tar zxvf /downloads/qmailrocks/qmail-1.03.tar.gz

tar zxvf /downloads/qmailrocks/ucspi-tcp-0.88.tar.gz

mkdir -p /package

chmod 1755 /package

cd /package

tar zxvf /downloads/qmailrocks/daemontools-0.76.tar.gz


6.Creating & setting qmail logging directories.


mkdir /var/log/qmail

cd /var/log/qmail

mkdir qmail-send qmail-smtpd qmail-pop3d

chown -R qmaill:root /var/log/qmail

chmod -R 750 /var/log/qmail


7.Setting up the supervise script directories.


mkdir /var/qmail/supervise

cd /var/qmail/supervise

mkdir -p qmail-smtpd/log qmail-send/log qmail-pop3d/log

chmod +t qmail-smtpd qmail-send qmail-pop3d


8.Setting conf-split and conf-spawn.

echo 211 > /usr/src/qmail/qmail-1.03/conf-split

echo 255 > /usr/src/qmail/qmail-1.03/conf-spawn


9.Applying qmail-ldap patch.


cd /usr/src/qmail/qmail-1.03/

gzip -d qmail-ldap-1.03-20060201.patch.gz

patch -p1 < /downloads/qmail-ldap-1.03-20060201.patch


10.Make following changes to the Makefile and then save & close this file.


vi Makefile

LDAPFLAGS=-DQLDAP_CLUSTER -DEXTERNAL_TODO -DDASH_EXT -DSMTPEXECCHECK -DALTQUEUE

ZLIB=-lz

MDIRMAKE=-DAUTOMAILDIRMAKE

HDIRMAKE=-DAUTOHOMEDIRMAKE

SHADOWLIBS=-lcrypt

DEBUG=-DDEBUG

Save & Close this file.


11.Building qmail.

make setup check

Please enter the hostname in place of <hostname> like mailserver.krishnagroup.co.in ./config-fast <hostname>


12.Build ucspi-tcp:


cd /usr/src/qmail/ucspi-tcp-0.88/

patch < /downloads/qmailrocks/patches/ucspi-tcp-0.88.errno.patch

make && make setup check


13.Build daemontools:


cd /package/admin/daemontools-0.76/src

patch < /downloads/qmailrocks/patches/daemontools-0.76.errno.patch

cd ..

package/install

If you take a look at the running processes on your server at this point, you should see the daemon "svscanboot" running.


14.LDAP controls files.


cd /var/qmail/control

echo 100 > concurrencyincoming

echo 255 > concurrencyremote

echo ./Maildir/ > defaultdelivery

Please enter the domain name in place of <domain-name> like krishnagroup.co.in echo <domain-name> > defaultdomain

echo /var/qmail/bin/dirmaker > dirmaker

Please enter the base dn in place of <base-dn> like dc=krishnagroup,dc=co,dc=in echo <base-dn> > ldapbasedn

echo 0 > ldapcluster

id -g vmail > ldapgid

Please enter root dn in place of <root-dn> for LDAP login like cn=manager,dc=krishnagroup,dc=co,dc=in echo <root-dn> > ldaplogin

echo /home/vmail > ldapmessagestore

echo qmailUser > ldapobjectclass

Please enter the root dn password in place of <rootdn-pass> echo <rootdn-pass> > ldappassword

echo 127.0.0.1 > ldapserver

id -u vmail > ldapuid

Please enter the hostname in place of <hostname> like mailserver.krishnagroup.co.in echo <hostname> > me

echo 127.:allow,NOPBS="" :deny > qmail-pop3d.rules

echo 80000000 > qmail-smtpd-softlimit

echo 80000000 > qmail-pop3d-softlimit

echo 3 > qmail-start-loglevel

Please enter the domain name in place of <domain-name> for which you want to receive mails like krishnagroup.co.in echo <domain-name> > rcpthosts

Please enter the hostname 

in place of <hostname> like krishnagroup.co.in

echo <hostname> > locals

Please enter the domain name in place of <domain-name> for which you want to receive mails like krishnagroup.co.in echo <domain-name> >> locals

17.OPENLDAP Integration with QMAIL-LDAP

cd /etc/openldap


cp /usr/src/qmail/qmail-1.03/qmail.schema schema/.


vi slapd.conf 


See slapd.conf(5) for details on configuration options.
This file should NOT be world readable.

include /etc/openldap/schema/core.schema include /etc/openldap/schema/cosine.schema include /etc/openldap/schema/inetorgperson.schema include /etc/openldap/schema/nis.schema include /etc/openldap/schema/qmail.schema

  1. Allow LDAPv2 client connections. This is NOT the default.

allow bind_v2

  1. Do not enable referrals until AFTER you have a working directory
  2. service AND an understanding of referrals.
  3. referral ldap://root.openldap.org

pidfile /var/run/openldap/slapd.pid argsfile /var/run/openldap/slapd.args

  1. Load dynamic backend modules:
  2. modulepath /usr/lib/openldap
  1. modules available in openldap-servers-overlays RPM package:
  2. moduleload accesslog.la
  3. moduleload auditlog.la
  4. moduleload denyop.la
  5. moduleload dyngroup.la
  6. moduleload dynlist.la
  7. moduleload lastmod.la
  8. moduleload pcache.la
  9. moduleload ppolicy.la
  10. moduleload refint.la

  17. moduleload valsort.la

  1. modules available in openldap-servers-sql RPM package:
  2. moduleload back_sql.la
  1. The next three lines allow use of TLS for encrypting connections using a
  2. dummy test certificate which you can generate by changing to
  3. /etc/pki/tls/certs, running "make slapd.pem", and fixing permissions on
  4. slapd.pem so that the ldap user or group can read it. Your client software
  5. may balk at self-signed certificates, however.
  6. TLSCACertificateFile /etc/pki/tls/certs/ca-bundle.crt
  7. TLSCertificateFile /etc/pki/tls/certs/slapd.pem
  8. TLSCertificateKeyFile /etc/pki/tls/certs/slapd.pem
  1. Sample security restrictions
  2. Require integrity protection (prevent hijacking)
  3. Require 112-bit (3DES or better) encryption for updates
  4. Require 63-bit encryption for simple bind
  5. security ssf=1 update_ssf=112 simple_bind=64
  1. Sample access control policy:
  2. Root DSE: allow anyone to read it
  3. Subschema (sub)entry DSE: allow anyone to read it
  4. Other DSEs:
  5. Allow self write access
  6. Allow authenticated users read access
  7. Allow anonymous users to authenticate
  8. Directives needed to implement policy:
  9. access to dn.base="" by * read
  10. access to dn.base="cn=Subschema" by * read
  11. access to *
  12. by self write
  13. by users read
  14. by anonymous auth
  16. if no access controls are present, the default policy
  17. allows anyone and everyone to read anything but restricts
  18. updates to rootdn. (e.g., "access to * by * read")
  20. rootdn can always read and write EVERYTHING!
  1. ldbm and/or bdb database definitions

database bdb

  1. suffix "dc=my-domain,dc=com"

suffix "dc=krishnagroup,dc=co,dc=in"

  1. rootdn "cn=Manager,dc=my-domain,dc=com"

rootdn "cn=manager,dc=krishnagroup,dc=co,dc=in"

  1. Cleartext passwords, especially for the rootdn, should
  2. be avoided. See slappasswd(8) and slapd.conf(5) for details.
  3. Use of strong authentication encouraged.
  4. rootpw secret

rootpw root1234

  1. rootpw {crypt}ijFYNcSNctBYg
  1. The database directory MUST exist prior to running slapd AND
  2. should only be accessible by the slapd and slap tools.
  3. Mode 700 recommended.

directory /var/lib/ldap

  1. Indices to maintain for this database

index objectClass eq,pres index ou,cn,mail,surname,givenname eq,pres,sub index uidNumber,gidNumber,loginShell eq,pres index uid,memberUid eq,pres,sub index nisMapName,nisMapEntry eq,pres,sub

  1. Replicas of this database
  2. replogfile /var/lib/ldap/openldap-master-replog
  3. replica host=ldap-1.example.com:389 starttls=critical
  4. bindmethod=sasl saslmech=GSSAPI
  5. authcId=host/ldap-master.example.com@EXAMPLE.COM
