Hi, MMC shares permission configuration is required by an AD administrator. I would like to add the admin users parameter to the Samba 3.0.24 server to provide this functionality, however I have some security concerns: Would it be possible for a connected user to fake the SID of an Administrator, and hence gain root access to the share? Does adding the admin users entry in the [globals] section differ in any way from manually adding it under each share? Cheers, Dave [global] workgroup = ADDOMAIN printcap name = /dev/null cups options = raw map to guest = Bad User include = /etc/samba/dhcp.conf logon path = \\%L\profiles\.msprofile logon home = \\%L\%U\.9xprofile logon drive = P: usershare allow guests = true idmap uid = 10000-20000 idmap gid = 10000-20000 use sendfile = true max xmit = 65535 strict locking = false strict sync = true add user script = /usr/sbin/useradd -s /bin/false %u delete user script = /usr/sbin/userdel %u server string realm = ADDOMAIN.HERE.COM security = ADS winbind separator = + winbind enum groups = true winbind enum users = true wins server = 192.168.4.77 client schannel = no admin users = ADDOMAIN+administrator [homes] comment = Home Directories valid users = %S, %D%w%S browseable = false read only = false inherit acls = true [scratch] path = /mnt/scratch comment = scratch writeable = true guest ok = true sync always = false follow symlinks = true wide links = true ...
