[Samba] some question about BDCs

I want to set up SaMBa PDC and BDC with LDAP. I read the TOSHARG2, but don't

Ok, I understand until that, but:

So, when I have SaMBa PDC (with master LDAP) and BDC (with slave LDAP), can
BDC update machine and/or user information or not? As I understood, only the
LDAP solution is suitable for a PDC-BDC setup, because "domain member
servers and workstations periodically change the Machine Trust Account
password", so BDC has to update some data.
As I understood, BDC can change at least Machine Trust Account passwords.
Additional question: can a user change his/her login password, when he/she
connected to the BDC (in case PDC is available and in case PDC is
temporarily unavailable)? I read in TOSHARG2 too that in the BDC's smb.conf,
I don't need user/group modification scripts, so I guess, I cannot
add/modify them from the BDC.
