[Samba] Access denied on shares, why?

I've strange access problem. I'm migrating samba server from Suse to
Ubuntu, and seems like it won't work like expected. All the time
problem is that normal users without admin rights can't access shares.
They can access their own home directories, but not common shares which
are limited to some groups.

Running samba 3.5.11. Below is output from few commands, config file
and 2 snippets of logs as links (too big to include to this
email). Logs are quite long, but with log level 2 there was nothing
relevant, and loglevel 3 prints out a lots of log :-(

If I have forgot to give some relevant information, don't hesitate to
ask. All hints are welcome, I'me getting desperate with this.
