Hi, seeing as you are using Debian Wheezy, you could start again with a 
clean install, add backports to /etc/apt/sources.list, then install 
samba4 from backports. This will get you version 4.1.11 (but 4.1.13 is 
in sid and will presumably get to backports shortly), you can also 
install bind 9.9.5 from backports if required. Once you have all your 
required packages installed, you can then join this computer to your 
domain as another DC, everything should replicate to your new DC. 
Transfer all the FSMO roles (including the two 'hidden' DNS ones) to the 
new DC, or seize them, turn off the old DC and tidy up. OK, I know this 
is a very simplistic view of the process and that it will be a bit more 
involved, but I cannot see any other way of getting the passwords
