This is the easy part. Restart the server:

root#  /etc/init.d/ldap restart
Stopping slapd:                                            [  OK  ]
Checking configuration files for slapd: config file testing succeeded
Starting slapd:                                            [  OK  ]

Then, using ldapsearch , test an anonymous search with the -ZZ ^[12] option:

root#  ldapsearch -x -b "dc=ldap,dc=abmas,dc=biz" \
        -H 'ldap://ldap.abmas.biz:389' -ZZ

Your results should be the same as before you restarted the server, for example:

root#  ldapsearch -x -b "dc=ldap,dc=abmas,dc=biz" \
    -H 'ldap://ldap.abmas.biz:389' -ZZ
