1. Use the ldapsearch tool to locate a specific entry.
    $ bin/ldapsearch -h server.example.com -p 389 -D "cn=admin,dc=example,dc=com" \ 
      -w password -b dc=example,dc=com "(uid=user.2004)"
  2. Use the ldapmodify command to change attributes from the command line. Specify the modification using the changetype:modify directive, and then specify which attributes are to be changes using the add and replace directive.
    In this example, we add the postOfficeBox attribute, change the mobile and telephone numbers of a specific user entry. The postOfficeBox attribute must be present in your schema to allow the addition. The three changes are separated by a dash ("-"). When you are done typing, you can press CTRL-D (Unix EOF escape sequence) twice or CTRL-Z (Windows) to process the request.
    $ bin/ldapmodify -h server.example.com -p 389 -D "cn=admin,dc=example,dc=com" -w password
    dn: uid=user.2004,ou=People,dc=example,dc=com 
    changetype: modify 
    add: postOfficeBox 
    postOfficeBox: 111
