[Samba] Allow self password change using LDAP(s) with Samba4

[Juan Asensio Sánchez]

Hi

Thanks all for your responses. The users can now change their own password
adding and removing the unicodePwd attribute, using the correct method to
generate the password value.

Now, I have a problem, because the users who have the option to force to
change the password in the next login checked, can't bind to the LDAP
server in order to change their password. Is there any way to do this,
using LDAP(s)?
