pwdEndTime usage

Hello all,

I updated our slapd daemon from 2.4 to 2.5 and want to use pwdEndTime operation attribute I read a lot of docs and can not find how I can add this attribute for all existing users.

It is an internal operation attribute that was introduced in slapd version 2.5 (OpenLDAP 2.5+ now ships the ppolicy schema hard-coded in the overlay slapo-ppolicy)

So as I see this attribute has no true/false or other flag (it is internal scheme attribute), which allows me to add it to dn: cn=passwordDefault,ou=Policies,dc=zone,dc=net or policy overlay olcOverlay={0}ppolicy,olcDatabase={1}mdb,cn=config

os is there any way I can enable it and update existing users with pwdEndTime attribute?
