If I understand your question correctly, initally it wasn't. Then I did "net
sam mapunixgroup webdev", but this didn't seem to have any effect.

I suppose as domain user. I am sitting at my Windows computer, logged in to
domain as DOMAIN\lz and connecting to a share at the Unix computer. The user
named "lz" also exists on the Unix computer. I was thinking that Samba would
map DOMAIN\lz the Windows user to lz the Unix user and use this user's group
membership.

I guess I am getting confused here. Are "local nested groups from winbindd"
the Unix local groups? If yes, this is what I need, but I'm failing to grasp
how to make them work.

Thanks,
Leonid
