if you replicated the ldap data base to the slave ldap and setup
the bdc to use the slave ldap auth will work.
If you setup the users profiles and homes hosted to the bdc
machine this will work too.
Usally your pdc is in an other office over vpn
so the users in this office should have their homes on the bdc.
But there are serveral other setups thinkable, you will have the profile
and homes if the machine on which they are hosted is connectable by the 
win client machines so it could be i.e a nas server too.
If you want a redundant setup pdc bdc with homes and profiles
you have to do a permanent replication from the pdc ( if your homes are 
there ) to the bdc.
You can also yous a 3 machine and mount homes and profiles via nfs
to the bdc and the pdc....
So there are many setups you can use, choose what fits best to your needs.
