LDB is the database engine used in Samba4. For further information see .
Installing in debian/ubuntu:
apt-get install python-ldb
Tests written in Python should be under this namespace. This includes both unit and integration tests.
All RPC protocols have python bindings avaiable generated by PIDL and exposed as samba.dcerpc.protocol
There is some other modules, we need to describe them there.
