Hi All, I have three of these command I use to map my UNIX groups to Windows: net groupmap add ntgroup="Remote Desktop Users" \ unixgroup=TermServ rid=5001 type=d Problem: I seem to have to re-enter this every so often. I am presuming after a kernel update and reboot. It may have been after stopping and restarting smb. Is "net groupmap add ntgroup" volatile? Do I have to run this out of my rc.local? Every time I stop and restart smb? What am I missing? Many thanks, -T $ cat /etc/redhat-release CentOS release 5.3 (Final) $ uname -r 2.6.18-128.1.14.el5 $ rpm -qa \*samba\* samba-common-3.0.33-3.7.el5 system-config-samba-1.2.41-3.el5 samba-3.0.33-3.7.el5 samba-client-3.0.33-3.7.el5
