When user tries to write to network drive (map network drive in windows)
or

After weeks of sambanuss (local sysadmin slang, means debugging) and
playing around with different configurations... I found (ugly) solution to
my problem.

I added "guest ok = yes" to global section of smb.conf and all was
well
again.

Meanwhile, in logs:
somerandompc (172.xx.xx.xx) connect to service usershare initially as user
nobody (uid=65534, gid=65534) (pid 30586)

But perms/owner/etc are correct. Also I didn't find any security
implications related to "guest user = ok" .
I can live with that.

Someday, if I'm feeling better, I'll submit a ticket to bugzilla.

Have a nice summer.
