Issue begins with 3.0.23 -> 3.0.22 works correctly!
When I have SMB server 3.0.23 (domain_member) joined to domain (domain is on samba 3.0.23 too), and I not use winbind and i have unix group named group and in share i have valid users = @group it does not allow me to connect to share.
When i use istead of @unix_group -> @WINDOWS.DOMAIN\windows_group it works
relevant extract from log file (user = solarz group = users - user solarz is in unix group users):
[2006/07/17 15:49:16, 3] lib/util_sid.c:string_to_sid(223)
