Nope, I did try installing them now, made no difference.
I have backup-scripts running on the server for months, and it worked before.

Can`t get wbinfo to report anything but errors, I am using user/domain/pass file with smbclient,
There is no sophisticated authentication AFAIK, and the issue just seems that samba sends data in bigger chunks
than the server accepts, the patch limits this. This does not seem anything related to login/auth.

Kind regards,
Norbert
