Hi, I'm running samba (on debian woody) as PDC for Win2K,98 and XP clients. What is the difference between: add user script = /usr/sbin/useradd -d /dev/null -g machines -s /bin/false -M %u [ seen on p.399 in O'Reilly Samba Book ] and add user script = /usr/sbin/useradd -d /dev/null -g machines -s /dev/null -s /bin/false %m$ [ seen on SuSE's Office server and various websites ] in the global section. Which version do I have to use? Thanks Marcus
