If that is the case, how come if I type my password to login, I get
logged in ?

That is correct.

Whilst you cannot read the unicodePWD attribute over ldap, you can set
it via ldap. you need to do it as a modify, first delete the existing
unicodePWD attribute and then add the new one. The password must be
base64 encoded inside double quotes. 
Finally, you must do all of this over SSL.
