samba - Jan 2015 - Samba4 Android port and Python auth modules

Hello All,

First post. Just ported Samba4 to a native Android/ARM platform -- quite a bit
more work than Samba3. Moved to Samba4 to pick up AD support.

The smb and nmb daemons fire up and appear to operate correctly, at least as
good as Samba3. However, when trying to use samba-tool to create/list users,
etc. I run into the following:

ERROR(<type 'exceptions.AttributeError'>): uncaught exception -
'module' object has no attribute 'session_info'

Which I interpret to mean that the session_info attribute is not present in
samba.dcerpc.auth, but it is. I am a Python and Samba novice, but it appears
that samba.auth is overshadowing samba.dcerpc.auth, or vice-versa. When I run
python interactively, I can import both modules, but I only see the attributes
for the first module imported - i.e. if samba.auth is imported prior to
samba.dcerpc.auth, a dir of samba.dcerpc.auth will return samba.auth attributes,
which presumably causes the AttributeError.

Any help to further debug or resolve this issue would be greatly appreciated.

Cheers,
-John

Oooh oooh oooh ! Can you post the code changes you
needed to do the port please ?

I'm excited :-).

Jeremy,

I will post the code changes soon, after reading the guidelines on how to do it
properly. :-)

If you are starting and running the smbd & nmbd daemons, then samba-tool 
wouldn't work, you are still in 'classic' mode, you need to
provision
samba as an AD DC with samba-tool (full instructions are on the wiki) 
before samba-tool will create users.
