I have been reading the archives and have not seen this question quite this way. Setup RH EX 3 Samba 3 W2k3 domain The students authenticate against the passwd/shadow file or smbpasswd depending on what resource they are accessing. I use passwd sync and the set their passwords in a web browser on smbpasswd I would like to make some of the resources available from this server to Faculty/staff. Can I add authentication against the W2k3 domain without messing up the students. The students do not exist in the W2k3 domain. Thanks CS
