Deleted objects ??

Run on the Samba DC: ldbsearch --cross-ncs --show-binary -H $(samba -b | 
grep 'PRIVATE_DIR' | sed 's/   PRIVATE_DIR: //')/sam.ldb -P > AD.ldif

This will dump the entire AD into an ldif

You can probably do something similar against the Windows DC's by 
replacing the '$(samba -b | grep 'PRIVATE_DIR' | sed 's/ PRIVATE_DIR: 
//')/sam.ldb' with 'ldap://DC_NAME' , where 'DC_NAME' is the DC's 
hostname, and replace '-P' with '-U Administrator'. You will also need 
to change the ldif file name.

Hard to tell, deleted objects, or collisions, or tombstones ???
