USING VPOPMAIL WITH LDAP USING VPOPMAIL WITH LDAPOriginal of this document is available from http://www.bowe.id.au/michael/isp/vpopmail-ldap.htm
Note that I am not an LDAP expert, so some of the terminology used within this guide may not be 100% correct. I wrote this guide because many people on the vchkpw mailing list had questions about how to get vpopmail/ldap running. The docs we had so far (below) were a little difficult to understand and follow for an LDAP beginner, so I decided to put together this doc in the hope of presenting an easy-to-follow installation guide.
OpenLDAP can operate with a number of database filesystems. For this example we are going to use the bdb database system.
Download/compile BDB
cd /usr/local/src wget http://www.sleepycat.com/update/snapshot/db-4.2.52.tar.gz tar xzf db-4.2.52.tar.gz cd db-4.2.52 cd build_unix ../dist/configure make make install cd ..
Download/compile OpenLDAP
http://www.openldap.org/software/download/ wget http://www.planetmirror.com/pub/openldap/openldap-release/openldap-2.1.23.tgz tar xzf openldap-2.1.23.tgz cd openldap-2.1.23env CPPFLAGS=-I/usr/local/BerkeleyDB.4.2/include \ LDFLAGS=-L/usr/local/BerkeleyDB.4.2/lib \ ./configuremake depend make make install cd ..
Make the user accounts
# If you are using RH8.0, you will probably need to run this following command, # because RH8.0 comes preconfigured with UID/GID 89 allocated to postfix # # userdel postfix groupadd -g 89 vchkpw useradd -g vchkpw -u 89 -d /home/vpopmail vpopmail# We recommend you use the user and group id's of 89. The FreeBSD folks # have reserved 89 for the group and 89 for the user for vpopmail. Feel # free to have the OS assign the group/user id (for example, Solaris won't # allow gid 89).
Download and unpack the source
cd /usr/local/src wget http://telia.dl.sourceforge.net/sourceforge/vpopmail/vpopmail-5.4.4.tar.gz tar xzf vpopmail-5.4.4.tar.gz chown -R root.root vpopmail-5.4.4 cd vpopmail-5.4.4
Setup the LDAP support in the vpopmail sources
vi vldap.h #define VLDAP_SERVER "localhost" #define VLDAP_PORT LDAP_PORT #define VLDAP_USER "cn=vpopmailuser, o=vpopmail" #define VLDAP_PASSWORD "vpoppasswd" #define VLDAP_BASEDN "o=vpopmail"
Compile vpopmail
./configure --enable-auth-module=ldap make make install-strip
Copy the vpopmail ldap schema into the OpenLDAP schema directory
cd ldap cp qmailUser.schema /usr/local/etc/openldap/schema
Configure OpenLDAP to host the vpopmail database
cp slapd.conf /usr/local/etc/openldap chmod 600 /usr/local/etc/openldap/slapd.conf chown root.root /usr/local/etc/openldap/slapd.conf
Start the OpenLDP server
/usr/local/libexec/slapd
If all goes well, 'ps axf' should give something like this :
18415 ? S 0:00 /usr/local/libexec/slapd 18416 ? S 0:00 \_ /usr/local/libexec/slapd 18417 ? S 0:00 \_ /usr/local/libexec/slapd
Now create the vpopmail database in the LDAP system
ldapadd -f vpopmail.ldif -x -w vpoppasswd -D'cn=vpopmailuser,o=vpopmail'
If all goes well you will see something like :
adding new entry "o=vpopmail"
Get the ldap server to confirm that the vpopmail database exists
ldapsearch -x -b 'o=vpopmail'
Now you should be right to go!
As you start adding domains and users, the ldap directory tree will eventually look like this :
vpopmail (o)somedomain1.com (ou)someuser1 someuser2 someuser3somedomain2.com (ou)someuser1 someuser2 someuser3

need to bump up the softlimit for the pop3d script..
