to a SAMBA PDC. Did I read this correctly? Has anything changed since then. If it can't be done, can anyone recommend another solution that has worked for them? I also would like it if SAMBA, Courier, Postfix could share the same username/password file. All of the above I mentioned (According to my reading) support the reading of /etc/passwd, so why would one want to use PAM or LDAP etc for authentication. Please forgive me for any stupid questions I may ask, as I've been using LINUX for only 4 months. I love it though.... can't get enough.... and the communities are great! Thanks! IRV
