Unfortunately not. Would disabling SMB2 on Windows 7 be comparable?

I just checked out the git repository and compiled it. But I don't know
how to properly use upgrade_from_s3. I tried it with
# setup/upgrade_from_s3 /var/lib/samba /etc/samba/smb.conf
but I got the following error:
Reading Samba3 databases and smb.conf
No realm specified in smb.conf file, assuming 'PRAXIS'
Traceback (most recent call last):
  File "setup/upgrade_from_s3", line 86, in <module>
  File "bin/python/samba/upgrade.py", line 415, in upgrade_provision
  File "bin/python/samba/provision.py", line 1069, in provision
    domainsid = security.dom_sid(domainsid)
TypeError: argument 1 must be string without null bytes, not str

I did not find any documentation for the script and the source code itself
also didn't give me any clues if I supplied the correct arguments.

I would really prefer using the upgrade script to provisioning a new user
database as this would probably mean I would have to change domains an all
clients when I want to switch back and forth between Samba 3 and 4.


Accept people for what they are -- completely unacceptable.
