Bug Description

Trying to share a folder on desktop called "shared", the required software is installed and all seems well.

Options selected are :

Share this folder: ticked
Share name: shared
Comment: Random Shares
Allow others to create and delete files in this folder: not ticked
Guest access: ticked

When trying to access share from windows the share is viewable using the \\ipadddress, however when clicking on it windows displays a message:

Share is not accessible. You might not have permission to use this network resource. Contact the administrator of the server to find out if you have access permissions.

No network provider accepted the given network path

My /var/og/samba/ log file contains the following:

process_usershare_file: stat of /var/lib/samba/usershares/shared failed. Permission denied
[2010/04/14 13:35:11, 0] smbd/service.c:988(make_connection_snum)

Is it a regression ?

Did this use to work properly with a previous release ?

Yes, it worked in Ubuntu 9.10.

samba.log Edit (1.7 KiB, text/plain)

I think I'm also affected of this bug.
attaching file from "tail -f /var/log/samba/log.*" from the moment when i try to mount smb://confiq-bigcomp/video (confiq-bigcomp is local machine)

Interesting is that shared folder is "Video" and not "video", also this happened on clean Ubuntu Lucid Install!

I have this bug too, and I figured out that the problem is that the whole path to the directory should be accessible (but not writable).

/home/username/Desktop/

/home should be at least o+rx
/home/username should be at least o+rx
/home/username/Desktop/ should be at least o+rx

Per Nicolo's remarks, they are spot on. Encrypting home directories is also a common choice that is incompatible with sharing the home directory. Public directory, as always, remains sharable.

Quick brainstorm on fixing this - Perhaps a script that works under sudo that:
(a) If home directory is encrypted, advise user to share stuff out of ~/Public;
(b) Run a script under sudo, perhaps controlled by a group (samba-sharers?) that runs a mount --bind ${HOMEDIR}/Public/share /var/lib/samba/usershares/${SHARENAME}
(c) net usershare /var/lib/samba/usershares/${SHARENAME}

Thoughts?

Cheers,

Michael
