Postfix Virtual Hosting With LDAP Backend And With Dovecot As IMAP/POP3 Server On Ubuntu Trusty Tahr 14.04 - Page 7

Step 8: Install and configure proftpd

First we will install proftpd and its requirements:

aptitude install proftpd proftpd-mod-ldap

Depending on your load you can decide between stand alone and inet.d.

Edit /etc/proftpd/proftpd.conf:

vi /etc/proftpd/proftpd.conf

And change from:

# Use this to jail all users in their homes
# DefaultRoot                   ~

To:

# Use this to jail all users in their homes
DefaultRoot      

And change:

# Alternative authentication frameworks
#
# Include /etc/proftpd/ldap.conf
#Include /etc/proftpd/sql.conf

To:

# Alternative authentication frameworks
#
Include /etc/proftpd/ldap.conf
#Include /etc/proftpd/sql.conf
             ~

Now edit /etc/proftpd/modules.conf:

vi /etc/proftpd/modules.conf 

And change from:

# Install proftpd-mod-ldap to use this
#LoadModule mod_ldap.c

To:

# Install proftpd-mod-ldap to use this
LoadModule mod_ldap.c

And from:

# Install proftpd-mod-ldap to use this
# LoadModule mod_quotatab_ldap.c

To:

# Install proftpd-mod-ldap to use this
LoadModule mod_quotatab_ldap.c 

No edit /etc/proftpd/ldap.conf and set the following:

<IfModule mod_ldap.c>
#
#LDAPServer ldap://ldap.example.com
#LDAPBindDN "cn=admin,dc=example,dc=com" "admin_password"
#LDAPUsers dc=users,dc=example,dc=com (uid=%u) (uidNumber=%u)
#LDAPUseTLS on
#
#
#LDAPServer ldaps://ldap.example.com
#LDAPBindDN "cn=admin,dc=example,dc=com" "admin_password"
#LDAPUsers dc=users,dc=example,dc=com (uid=%u) (uidNumber=%u)
#
LDAPServer                      ldap://127.0.0.1/??sub
LDAPBindDN                      "cn=phamm,o=hosting,dc=example,dc=tld "readonly"
LDAPUsers                       "o=hosting,dc=example,dc=tld"  "(&(uid=%v)(objectclass=posixAccount))"
LDAPDefaultGID                  33
LDAPDefaultUID                  33
LDAPForceDefaultGID             True
LDAPForceDefaultUID             True

</IfModule>

The following commands set the default user to www-data which suits me, you can change these values to suit your setup or leave them out to use the login username.

LDAPDefaultGID                  33
LDAPDefaultUID                  33
LDAPForceDefaultGID             True
LDAPForceDefaultUID             True

33 Is the uid/gid of my testing setup, it can be different on your setup.

This concludes the proftpd installation
