You will be asked a series of questions about how you'd like to configure the software.Omit OpenLDAP server configuration? NoDNS domain name?This will create the base structure of your directory path. Read the message to understand how it works.There are no set rules for how to configure this.

comes with enough utilities to manage the directory but the long
string of options needed can make them a burden to use.
The ldapscripts package
contains wrapper scripts to these utilities that some people find
easier to use.Install the package:

sudo apt-get install ldapscripts

#################################################

then add two nodes ou=Groups and ou=Users to the LDAP, before add a group to LDAP

a stupid bug:

if the passwd contain some special character like"@",","....anything like that, then you will get error when add group use 'sudo ldapaddgroup test',like:

error adding group to ldap

so,give it a simple 'secret' passwd, like 'dog','monkey',,,,

############################################################################################## step by step :

first:

1)sudo apt-get purge slapd
2)sudo apt-get install slapd ldap-utils
do like above each some stupid error occurs that you can't solve.

second:

sudo dpkg-reconfigure lapd #configure according to the link2 above, you'd better don't configure it by hand.

third:

sudo apt-get install ldapscripts #install a convenient tools

and then, configure ldapscripts's configure file /etc/ldapscripts/ldapscripts.conf, add sentences, like:

SERVER=localhost

BINDDN='cn=admin,dc=example,dc=com'

BINDPWDFILE='/etc/ldapscripts/ldapscripts.passwd'

SUFFIX='dc=example,dc=com'

GSUFFIX='ou=Groups'

USUFFIX='ou=Users'

fourth:

add passwd to ldapscripts.passwd file :

sudo sh -c "echo -n 'monkey' > /etc/ldapscripts/ldapscripts.passwd"

then: you can operate LDAP using ldapscripts commands according to link 1.

warning: ldapscript will always return 'error adding group qa to LDAP',if the group already exists
