uidNumber: 1000
gidNumber: 10000
userPassword: user123
gecos: John Doe
loginShell: /bin/bash
homeDirectory: /home/john
shadowExpire: -1
shadowFlag: 0

2) Add User to openLDAP.

sudo ldapadd -x -D cn=admin,dc=example,dc=com -W -f userinfo.ldif

3) Search User:

ldapsearch -xLLL -b "dc=example,dc=com"

ldapsearch -xLLL -b "dc=example,dc=com" uid=user
b) Displays comple info of User whose uid=use.




ldapsearch -xLLL -b "dc=example,dc=com" uid
c) Displays the dn of all the users in "dc=example,dc=com"

 4) If you make a mistake when entering your information you can execute the dialog again using:

sudo dpkg-reconfigure ldap-auth-config 

The results of the dialog can be seen in /etc/ldap.conf 

5) Change User Password:

sudo apt-get install ldapscripts

Next, edit the config file /etc/ldapscripts/ldapscripts.conf uncommenting and changing the following to match your environment:

SERVER=localhost
BINDDN='cn=admin,dc=example,dc=com'
BINDPWDFILE="/etc/ldapscripts/ldapscripts.passwd" SUFFIX='dc=example,dc=com'
GSUFFIX='ou=Groups'
USUFFIX='ou=People'
MSUFFIX='ou=Computers'
GIDSTART=10000
UIDSTART=10000
MIDSTART=10000

Now, create the ldapscripts.passwd file to allow authenticated access to the directory:
sudo sh -c "echo -n 'secret' > /etc/ldapscripts/ldapscripts.passwd" sudo chmod 400 /etc/ldapscripts/ldapscripts.passwd

	Replace “secret” with the actual password for your LDAP admin user.

The ldapscripts are now ready to help manage your directory. The following are some examples of how to use the scripts.

• Change a user's password:
  

  sudo ldapsetpasswd userid
  Changing password for user uid=userid,ou=People,dc=example,dc=com
