Hi,
I am in the process of upgrading from v3.0.20a to v3.0.23 with our
local passdb plugin. The plugin complies without any issues.
Our User DataBase contains all our users accounts but not system
accounts. With Samba v3.0.20a this wasn't a problem.
Why th change between v3.0.20a and v3.0.23 ?
Do you see any issues if I return a fake root account? Returning a
fake root account s a hack I would rather not perform.
Thanks
Paul
FYI - Yes smbd runs without a panic if I disable our custom passdb plugin.
See below for smbd v3.0.20a and smbd v3.0.23 start logs.
