[Samba] NT_STATUS_OBJECT_NAME_NOT_FOUND after installing the last git version

[Alain Foucher]

I have installed many different versions of Samba4 with success.

Now, i would install a new one with the git tool on an ubuntu 12.04.
I did the git clone with success.
The configure, make and make install ran with success.
I ran the provisioning command with success :
/usr/local/samba/bin/samba-tool domain
provision --use-rfc2307 --interactive

I test Kerberos and DNS (kinit, klist, host commands) without any problem.

In the log.samba and the log.smbd, i've got no error, Everything seems to be
allright (samba-tool dbcheck, wbinfo, ...).

But when i run the following command

smbclient -L localhost -U% (or any smbclient command)

i've got this message

session setup failed: NT_STATUS_OBJECT_NAME_NOT_FOUND

The version, i installed is the followin one :

Version 4.2.0pre1-GIT-001b958

Did i miss some issues ?

thanks

Alain

Might it just be a path issue ?
/usr/local/samba/bin/smbclient -L localhost -U%

Thank you very much for bringing this to our attention.

This is a (now) know regression that appears to have been introduced
recently with the change to use wbc_xids_to_sids. Garming and I were
able to isolate it down to one of these commits at the end of our work
day today:

I expect to further diagnose this tomorrow, but in the meantime I've
CC'ed the patch author and reviewer in case they have any insights.

In the meantime, you could assist by reverting each of these patches in
turn, and verifying that it does indeed resolve your issue.

Sorry,

Andrew Bartlett

Attached find a patchset that reverts the offending code. As
I don't have the time today to deal with this in an
appropriate manner, please review & push this until we have
a resolution for the problem this code causes.

Thanks,

Volker

I'd -1 these patches, but Andreas beat me to the review and +1ed them.

The main questions raised by this issue for me are:
* Auth code is tricky, but it does have a lot of tests. Why didn't they
catch this
* The last time I changed this code to support unixid-mappings instead
of plain uid/gid-specific mappings, I made fairly similar changes. I
still didn't catch the problem with the patches. Can the auth code be
simplified so the implications of changing it are better understood?

And last but not least a more personal question about code reviews and
reverts like this: How can we resolve things like that without leaving
the reviewer feeling like he wasted a lot of time on a review? I feel
silly enough not having caught the problem, but now I also feel like I
could have just spend the time I spent on the review drawing fluffy pink
unicorns and be more productive that way.

I for one don't feel like spending more time trying to follow up on this
issue now that the code is on the way out of master anyway. I also feel
like I'll rather practice my unicorn drawing skills than reviewing code
I can't care about enough to drop everything I'm doing and debug
potential issues before the 10-minutes-to-revert window has passed.

Cheers,
Kai

Please retry with current master. The patches that Andrew
Bartlett has kindly found to cause this are now removed
again.

Sorry for the inconvenience.
