setting password in ldap

Hi,

I have installed open ldap according to the order from this video:
YouTube - bowendenning's Channel

sudo apt-get install slapd
sudo apt-get install ldap-utils
sudo apt-get install phpldapadmin

The installaion was good.
However it did NOT ask from me any password.
After I enter to the phpldapadmin, I could not login since I had no password.
How can I set a password to the admin in ldap?
