dS )r a Simple Samba-specific LDB subclass that takes care
of setting up the modules dir, credentials pointers, etc.
Please note that this is intended to be for all Samba LDB files,
not necessarily the Sam database. For Sam-specific helper
functions see samdb.py.

:param url: Optional LDB URL to open
:param lp: Optional loadparm object
:param modules_dir: Optional modules directory
:param session_info: Optional session information
:param credentials: Optional credentials, defaults to anonymous.
:param flags: Optional LDB flags
:param options: Additional options (optional)
This is different from a regular Ldb file in that the Samba-specific
modules-dir is used by default and that credentials and session_info
can be passed through (required by some modules).
