Synchronizing Password Expiration

We have IDM 3.51 synchronizing among three eDirectory trees (production,
LDAP and ID vault) and Active Directory. Password synchronization is
set up and working. Now I need to synchronize password expiration. No
matter where a user changes her/his password, I'd like the 90-day timer
to reset everywhere. Do I need to edit the driver filter on the two
eDir-to-eDir drivers to synchronize the password-related values -- e.g.,
password expiration interval, password expiration time, login grace
limit and login grace remaining?

Thanks
