Guest samba share stops working when winbind is installed

[rivode]

Binary package hint: samba

I have a Samba share configured to provide read/write access without authenticating. This worked fine until I installed Wine. I removed wine, and it worked fine again. I narrowed the offending package down to winbind.

The share is configured like this:

[rwshare]
path = /data/sharerw
read only = no
writeable = yes
guest only = yes
guest ok = yes
create mask = 0664
directory mask = 0775
force group = download

I also have a read-only share, which works fine regardless of whether winbind is installed:

[share]
comment = General share
path = /data/Share
read only = yes
guest only = yes
guest ok = yes

Upon trying to connect to the read-write share with an fstab entry, I get this on the (Debian) client:

Anonymous login successful
3505: tree connect failed: ERRHRD - ERRgeneral (General failure.)
SMB connection failed

and using smbclient //localhost/rwshare -U%:

Domain=[WORKGROUP] OS=[Unix] Server=[Samba 3.0.28a]
tree connect failed: NT_STATUS_NO_SUCH_GROUP

and this was in /var/log/samba/log.127.0.0.1:

I couldn't see any other messages that might suggest a problem.

This is probably the same as Bug #277327.

I fail to reproduce this. Same versions installed, same share config, I manage to access the share with or without winbind installed.

Here is what I did:
- Install samba, pushed share config to /etc/samba/smb.conf, restarted and checked I could access the share ok
- Install Wine, tried accessing the shares just after that : ok
- Restart samba, try access the shares : ok
- Reboot, try access the share : ok

I must be missing something, could you attach a minimal (but complete) smb.conf that allows you to reproduce the issue ? Did you configure any other file ?

Thierry, while I haven't recently tried to reproduce this, I was able to get test-samba.py from the qa-regression-testing scripts to fail with winbind installed. Please see bug #244411 for more information.

[Thierry Carrez (ttx)]

Yes, I reproduced it with the test script, that's why I marked this one as a duplicate. The version in intrepid seems fixed.
