Install PureFTPD from EPEL yum repo:
# yum install pure-ftpd
iRedMail generates a read-only LDAP bind dn cn=vmail,dc=xxx,dc=xxx
during
installation, so it's perfect to query user accounts with this dn.
You can find the full dn and password in /etc/postfix/ldap/catchall_maps.cf
:
# grep 'bind_' /etc/postfix/ldap/catchall_maps.cf
bind_dn = cn=vmail,dc=example,dc=com
bind_pw = InYTi8qGjamTb6Me2ESwbb6rxQUs5y
/etc/pure-ftpd/pureftpd-ldap.conf
and update parameters below:LDAPServer localhost
LDAPPort 389
LDAPBaseDN o=domains,dc=example,dc=com
LDAPBindDN cn=vmail,dc=example,dc=com
LDAPBindPW InYTi8qGjamTb6Me2ESwbb6rxQUs5y # cn=vmail password
LDAPDefaultUID 2000 # <- UID of `vmail` user.
LDAPDefaultGID 2000 # <- GID of `vmail` user.
LDAPFilter (&(objectClass=PureFTPdUser)(mail=\L)(FTPStatus=enabled))
LDAPHomeDir FTPHomeDir # <- New LDAP attribute, we will add it later.
LDAPVersion 3
FTPHomeDir
to
store per-user FTP home directory. Default schema uses homeDirectory
.# wget https://bitbucket.org/zhb/iredmail/raw/default/extra/samples/pureftpd.schema
# mv pureftpd.schema /etc/openldap/schema/
/etc/openldap/slapd.conf
, include pureftpd.schema
after iredmail.schema
:include /etc/openldap/schema/iredmail.schema
include /etc/openldap/schema/pureftpd.schema # <-- Add this line.
/etc/openldap/slapd.conf
, append required indexes for attributes
defined in pureftpd.schema
:# Indexes for Pure-FTPd LDAP attributes.
index FTPQuotaFiles,FTPQuotaMBytes eq,pres
index FTPUploadRatio,FTPDownloadRatio eq,pres
index FTPUploadBandwidth,FTPDownloadBandwidth eq,pres
index FTPStatus,FTPuid,FTPgid,FTPHomeDir eq,pres
We're going to store all FTP data under /home/ftp/
directory, so let's create
/home/ftp/
first, directory owner MUST be root
user.
# mkdir /home/ftp/
# ls -dl /home/ftp
drwxr-xr-x 3 root root 4096 Jun 7 20:18 /home/ftp/
Restart Pure-FTPd and OpenLDAP services:
# /etc/init.d/ldap restart
# /etc/init.d/pure-ftpd restart
# netstat -ntlp | grep pure-ftpd
tcp 0 0 0.0.0.0:21 0.0.0.0:* LISTEN 2062/pure-ftpd (SERVER)
tcp 0 0 :::21 :::* LISTEN 2062/pure-ftpd (SERVER)
With script shipped in iRedMail, you can quickly create NEW mail user which has pureftpd service support.
tools/create_mail_user_OpenLDAP.sh
under your iRedMail directory
(e.g. /root/iRedMail-0.9.4/tools/create_mail_user_OpenLDAP.sh
), update
paraemters below with correct values:LDAP_SUFFIX="dc=example,dc=com" # <- Change the LDAP suffix
BINDPW='passwd' # <- Password for the bind dn `cn=Manager,dc=example,dc=com`
PUREFTPD_INTEGRATION='YES' # <- Set to 'YES' to enable the pureftp inteegration
FTP_STORAGE_BASE_DIRECTORY='/home/ftp' # <- Change it to the ftp home directory
user1@example.com
. The default
password is same as user name (user1
) by default.# bash create_mail_user_OpenLDAP.sh example.com user1
adding new entry "ou=Users,domainName=example.com,o=domains,dc=example,dc=com"
ldapadd: Already exists (68)
adding new entry "ou=Groups,domainName=example.com,o=domains,dc=example,dc=com"
ldapadd: Already exists (68)
adding new entry "ou=Aliases,domainName=example.com,o=domains,dc=example,dc=com"
ldapadd: Already exists (68)
adding new entry "mail=user1@example.com,ou=Users,domainName=example.com,o=domains,dc=example,dc=com"
You can now login to both webmail and FTP service as this user.
iRedMail doesn't open port 20 and 21 by default, you must open them first.
/etc/sysconfig/iptables
and set correct values:-A INPUT -p tcp --dport 20 -j ACCEPT
-A INPUT -p tcp --dport 21 -j ACCEPT
# service iptables restart
You can use windows FTP client or Linux ftp client (e.g. command line ftp
client lftp
or GUI client FileZilla
) for
testing.
We use lftp
for testing below:
$ lftp localhost
localhost:~> debug 4
localhost:~> login user1@example.com user1 # <-- input the username and password
user1@example.com@localhost:~> ls
