Hi All I have joined SAMBA server with ADS and would like to know the correct interpretation for mentioning the groups defined in AD, local (/etc/group) if that possible into the smb.conf So far I have used DOMAIN\USER1 with spaces or commas, or "%D\USER1" working Ok But if the user list is large and we don't have already a existing AD group, Is it possible to create a local group /etc/group and map all the USER1, USER2 AD users into /etc/group? I have also seen with Security=Domain, we can correctly resolve to local (/etc/groups) , if all the users are defined into the AD, what is the best way to user samba as the Security - Domain or ADS ? Please advise and let me know if there are any pointers. Regards, Yash
